Rockbox

If your Ipod accessory doesn’t work with rockbox, you can report it here.

Please put your device name, Ipod model, and tested rockbox version in your post. If some but not all features work, be sure to mention that in your post.

Edit by rasher:
You should also add your results to this page page: http://www.rockbox.org/twiki/bin/view/Main/IpodAccessories

For any developers who might work on IAP support, please add patches to this task, so potential testers are notified.

Attached is a patch that starts support for the sort tags specified in ID3 v2.4. It adds three new tags to the tagcache system, sortartist, sortalbum, and sorttitle which are drawn from the TSOA/TSOP/TSOT tags.

This is only the beginning and is very, very lightly tested (i.e. it compiles and doesn’t seem to break anything).

This is an almost complete rewrite of the current dict plugin.

It is based on the stardict dictionary file format and acts as a viewer for .idx files.

Most important features are:
- fuzzy search by showing all articles that start with a certain word
- quite fast search (binary search, same as the current dict plugin)
- scrolling for long descriptions
- handles even huge dictionaries (e.g. Wikipedia)

When first opening a dictionary, an offset table is created to provide random access to the index file.

Stardict dictionaries can be used almost directly but all files have to be uncompressed.

I created another patch, which adds a “Dicionaries” entry to the root menu (FS# 6630). It shows all dictionaries placed in “/dicts”.

Some more information may be found in a thread about an older version on MisticRiver http://www.misticriver.net/showthread.php?p=546738

Hi, this is a codec pack containing all codecs based on blargg's
Game_Music_Emu library.

I have ported all code to C to work in ROCKbox, and i have replaced the
MAME versions of some emulators with others compatible with the GPL license.
It was a lot of work but i did it because i really love chiptune music and having the
possibility to listen to a lot of classic video game system's music in a small player
is really great ;).

Original Game_Music_Emu library here: http://slack.net/~ant/libs/audio.html

Tested on: Sansa Fuze v2
Created from revision: 30084

The following formats are contained in the pack:

- AY (ZX Spectrum, Amstrad CPC)
- GBS (Nintendo Game Boy)
- HES (NEC TurboGrafx-16, PC Engine)
- KSS (MSX Home Computer, other z80 systems)
- NSF, NSFE (Nintendo NES, Famicom)
- SGC (Sega Master System, Game Gear, Coleco Vision)
- VGM, VGZ (Sega Master System, Mark III, Sega Genesis, Mega Driver, BBC Micro)

Additional features:

- 44100 Khz, stereo playback.
- Support all sound chips in NSF/NSFE formats.
- Support MSX-AUDIO and MSX-MUSIC in KSS format .
- Support ADPCM samples in HES format.
- Support for extended m3u playlists created specially for

some chiptune formats.

Known issuses:

- Some (or all) codecs might not work in some targets, specially

if they have an small iram size, or if the codec is too cpu intensive, 
like VGM and KSS.

- Subsong change is not working properly, specially when it happens

automatically.

- Most vgz tracks will be truncated due to the small amount of free

memory available to uncompress them.

- Some SCC+ soundtracks might not work correctly.

** There might be several bugs and issues to be found yet, so please feel free to

  report them here or to my mail address.

Special thanks to:

- Shay Green (blargg) the original author of the great Game_Music_Emu

library.

- Chris Moeller (kode54) who made some nice improvements to the library.
- Mitsutaka Okazaki, author of the YM2413 emulator.
- The OpenMSX team for the YM8950 emulator.
- Stéphane Dallongeville for the YM2612 emulator.
- Joshua Chang, Haiku Konaru and everyone else who has helped me to

test the codecs.

I've hunted this down here is what I found out.

from
http://developer.android.com/reference/android/view/KeyEvent.Callback.html

public abstract boolean onKeyDown (int keyCode, KeyEvent event)
Since: API Level 1

Called when a key down event has occurred. If you return true, you can first call KeyEvent.startTracking() to have the framework track the event through its onKeyUp(int, KeyEvent) and also call your onKeyLongPress(int, KeyEvent) if it occurs.

We need to return true and call KeyEvent.startTracking() from /android/src/org/rockbox/RockboxFramebuffer.java then set the interrupt flag from /firmware/target/hosted/button-android.c and find out what is passed back after a key release and handle that. I may not be a great programmer but this looks like the ticket to removing the BUTTON_REL work around from /firmware/target/hosted/android/app/button-application.c

This is a plugin designed to view the contents of either:
synchronised lyrics file (.snc/.lrc)
synchronised lyrics tag information (id3v2.3 SYLT - MP3 only)
unsynchronised lyrics file (.txt)
picture file containing lyrics (.bmp)

Button mappings currently coded for the following players:
iriver H1x0
iriver H3x0
iPod
iAudio X5
Toshiba Gigabeat

This task is to develop a stand alone command line interface for use with SAPI. This will be designed to run under Windows or WINE.

This will replace the platform dependent VB script currently in place adding new features and try to improve performance.

I have attached an initial release, run with -h option for usage info.

This is not completed had very litttle error handling and due to performance issues under wine I am considering a new server/client model for a future release.

This is a post that another user put in the forums that pretty much describes the problems I'm having exactly:

" I have a v1 sansa fuze and been using rockbox since 3.8.1 first came out.I just upgraded to 3.9,did not mess with a-n-y setting at all,pc is windows vista (latest sp).Whenever i drag and drop folders with mp3s in them(be it 58 mb or 300 mb or 600 mb) it starts to copy but halfway through,the process just freezes,clicking cancel freezes the windows explorer for 10 seconds then cancels it.Even worse,when i go check out my sansa fuze at my computer,it's recognized but when i click on it,shows as empty!? so i disconnect safely,theeeen….device needs a hard reset.So i say ok this has happened once or twice before but guess what? it happened again…5 TIMES each on 3 different usb ports.Uninstalled rockbox,went back to official firmware and it's all normal…

So i changed the screen to be always on during plugged in and this is the error i get

data abort at 30054264
FSR 0x8
( domain 0, fault 8 )
address 0xA00000BF "

I am running Windows 7 64-bit and experiencing the same issues. If the player doesn't lock outright, it gives the same error white screen described above. This seems to happen more frequently when copying folders that contain folders themselves, but I've had the problem occur on copying just one folder with no subfolders.

This patch is for the Sansa Fuze but easily modified for other players with scroll wheels.
apps/keymaps/keymap-[your player].c needs to be modified

This patch changes the keyboard input method for scroll wheel players to this:

Scrolling the wheel forward selects the column of the desired character moving right.
Reversing the wheel moves the keyboard cursor down (not left) to select the character.
Reversing again inserts the letter and resets the row and column to the top left.
Repeat…(right, down, right, down…)

The benefit is not leaving the scroll wheel or stopping to click anything.

The center select button is now always mapped to delete.
Left and right always move the edit position.
To make overshoot more forgiving reverse scrolling past the bottom of the keyboard moves the cursor to the top of the previous column.

The posted patch includes keymap changes for the Sansa Fuze. These are the changes required for a different target:
- { ACTION_KBD_UP, BUTTON_SCROLL_BACK, BUTTON_NONE },
- { ACTION_KBD_UP, BUTTON_SCROLL_BACK|BUTTON_REPEAT, BUTTON_NONE },
- { ACTION_KBD_DOWN, BUTTON_SCROLL_FWD, BUTTON_NONE },
- { ACTION_KBD_DOWN, BUTTON_SCROLL_FWD|BUTTON_REPEAT, BUTTON_NONE },
+ { ACTION_KBD_SCROLL_BACK, BUTTON_SCROLL_BACK, BUTTON_NONE },
+ { ACTION_KBD_SCROLL_BACK, BUTTON_SCROLL_BACK|BUTTON_REPEAT, BUTTON_NONE },
+ { ACTION_KBD_SCROLL_FWD, BUTTON_SCROLL_FWD, BUTTON_NONE },
+ { ACTION_KBD_SCROLL_FWD, BUTTON_SCROLL_FWD|BUTTON_REPEAT, BUTTON_NONE },

This patch will remove Morse code but preserves the unicode capability (not tested)

This patch modifies hardware registers for pclk & fclk in one instruction.

I’m currently testing it on Clipv2 to see if it gets rid of crashes

Whenever the HOLD switch is turned off, the hold icon in rockbox disappears, but hold actually doesn’t let go. I can’t use any keys until scroling is used. Scrolling left or right is the only thing that actually switches off hold. It can be pretty annoying as I use HOLD a lot.

The Case Game

Here is a variant of Deal or No Deal for Rockbox.

26 cases contain random amounts of virtual money. After choosing 1 case for yourself, you open the other cases until the banker makes you an offer to buy your case. If you choose to accept the offer the game ends and you receive that offer as your final score. By declining the offer, you continue to open the remaining cases until the next offer. If you decline all offers you get the amount that was in your case as your final score. If play continues until your down to 1 case plus the case you chose, you are given the option to swap cases.

Gameplay controls:

() While opening cases: pressing UP shows the remaining case amounts.

                      pressing DOWN shows the high scores.

() While deciding on an offer: pressing UP shows the previous offers.

                             pressing DOWN shows the high scores.

This game allows name entries into a high score board.

This game currently only works on color lcd screens (Sansa e200 176×220) or greater.

Apply the patch and place the .bmp files in the “apps/plugins/bitmaps/native/” directory.

Please post results for other platforms as well as comments. I tested the game out on the Gigabeat simulator and it seemed to work well.

“First Keypress Enables Backlight Only” doesn’t work on the 5G iPod. For example, if that’s enabled, the backlight is off and I press next track while at the WPS, Rockbox will go to the next track.

It seems like clickwheel event(s) generated when I touch the wheel turn on the backlight. When the button is pressed, the backlight is already considered to be on and the button press performs its usual action. If I carefully hold my finger still on the clickwheel, let the backlight fade, and then carefully press a button without moving my finger on the clickwheel, I am able to turn on the backlight without causing anything else to happen.

I don’t know what to do about this. Requiring a physical button press might be annoying. Removing this option on affected targets might be okay, because it’s easy to turn on the backlight by touching the clickwheel (and that doesn’t seem to cause anything else to happen). Another possibility is to require more or specific wheel events.

I set player type to iPod 5G because that’s all I have, but I expect this problem also exists on other clickwheel iPods. This problem exists on r20079 and r20033.

This patch adds an additional menu option to the list of WPS hotkey choices, “Announce Information”. This voices basic information about the player, currently playing file and current tracklist.

This feature reads a simple definition with a single line of no more than 20 characters from the file “announce.cfg” in the .rockbox directory.

This definition consists of a string of single character tokens, each of which announces a particular canned piece of information.

The tokens are:

A - current time
B - elapsed time and total length of the current track
C - current track number and total tracks in playlist
D - battery level as a percentage
E - battery remaining in hours and minutes
F - sleep timer remaining in minutes

If more than one token is specified, more than one piece of information is announced, so:

AB

would announce the time followed by elapsed time and track length

Multiple announcements may be bound to the hotkey by separating one or more groups of tokens with a “:”

A:DF

In this example, the first time the hotkey is pressed, the time is announced. If it is pressed again within 10 seconds, the battery level and sleep timer are announced and so on.

A space between tokens adds a short pause to the announcement.

If no announce.cfg file is present, the time is announced by default.

This patch converts LCD_{WIDTH,HEIGHT} into variables, allowing Rockbox to change screen size at runtime.

I’ve tried to make the changes as less intrusive as possible, but still, there will be some binsize increases.

Most of the #if’s were converted to C if()’s which should be functionally equivalent (and if the compiler is smart enough, no increase in binsize should occur).

In order to use this, just define DYNAMIC_LCD_SIZE in your target config and compile without plugins (if the preprocessor spits errors, try clearing ENABLEDPLUGINS in your Makefile).

What still needs to be done:
* figure a way out how to compile several rockbox logos into the binary and choose the correct one at runtime
* do something about the hacks in apps/bitmaps/SOURCES and apps/settings_list.c
* get the Android port working

Over the past month? the radio menu has been disappearing. When I reinstall the menu comes back and the radio works and the debug screen shows the radio.

When it re-initializes the DB, the radio disappears and the debug screen said that there's is no hardware.

If I manually deleted the DB files, the radio comes back…

A few other people on anythingbutipod forum have mentioned the same issue.

Still an issue August 1, 2007: r14133-070801

A first port of espeak running on rockbox.
Warning: Only tested on Sansa player!

I have skipped some advanced features of espeak, for example:
- mbrola
- on the fly Translator language switching (try: ‘spring’ with german selected)

Because this plugin is very basic, there is no file input selection.
It always reads from the ‘test.txt’ in the root.
You have to unzip the espeak-data to the root of your player.

This is a 3D maze done in vector graphics. I ported David Leonard’s program, which was done with the curses library. Initially, I wrapped the curses functions he used in order to draw the maze with putsxy().
This code is not used at the moment, as the vector graphics are easily scaled and more pleasing. The only issue I see is with the user map, which may be harder to draw on a smaller screen. I developed this on the iPod Video.

This is my first attempt at an open source project, and is a refresher in C for me. I apologize for style. I have tried to make the code as clear as possible.

After reading the irc log shortly after the flashlight plugin was committed i noticed that some want the ability back to finetune the colour of the display. This time i’ve added a fixed point version of the hsv_to_lcd version (thanks to amiconn) and added some more predefined colours. You can “skip” forwards or backwards to the nearest predefined colour (however, it’s probably not the nicest way of doing it i guess).

I’ve also implemented another request to switch the backlight on and off (even for non colour targets) and it now uses the remote backlight too.

Controls:
Targets with a 4 button cross:
Up/Down: fine tune
Left/Right: jump to next predefined colours (including white)
Select: switch backlight on and off

Targets with scroll wheel:
Scroll left/right: fine tune
Left/right or fwd/rew: jump to next predefined colours (including white)
Select: switch backlight on and off

I’ve tried to guess the most intuitive button layout on all targets and even use the remote buttons. However i only own a small number of targets so if you think it can be done better let me know.

Tested on iPod Video, Mini (sim), H300 (sim) and m:robe 100.

This patch modifies the CPU and peripheral bus clocks to hopefully gain some battery life. With this patch the CPU frequency can be either 31 or 186Mhz and the pclk is boosted from 31 to 62 Mhz while the CPU is boosted. The power draw of the CPU is proportional to the clock frequency and setting the frequency at or below what is required for playback keeps the power usage to a minimum because boosting to a frequency below 200Mhz is inexpensive. (Keeping the boosted CPU frequency below 200Mhz eliminates the need to wait for a voltage rise.)

I would appreciate feedback on battery life if anyone has the patience to run a battery bench.

As we know, rockbox will use the information provided by "good" mp3 encoders (e.g. LAME) to ignore the extra padding that occurs at the beginning and end of each mp3 file, so that true gapless playback can occur. Unfortunately we do not always have the luxury of encoding our mp3 files in this way but we might still want true gapless playback. This patch compensates for the use of "dumb" mp3 encoders that do not record the necessary information for this feature.

In cases where it does not detect the proper header information to trim off the extra padding, it will optionally skip up to a full frame of silence (or near silence) at the beginning and end of each track (if the trimming is already specified, this patch does not do any additional trimming).

This can potentially eliminate up to a frame of "real" silence at the beginning or end of a track, but in terms of audibility, that would be completely unnoticeable (and it would only happen on these badly-encoded tracks), while the extra silence is an audible annoyance.

I have added an option to the Playback Settings menu so that the user can disable it if desired.

This adds asplash and asplashf (and vasplashf for internal use) which normal splashes but can be aborted with button presses.

Additionally, they return the action received (for CONTEXT_STD) so that the caller may handle aborts differently depending on the button.

Also I converted a few annoying splashes to use it (when loading themes, wps, fonts etc and the resume failed splash)

Overview:

This adds the hotkey [short home], and allows you to stop/start play more or less anywhere [long home] which I find quite useful. Hopefully, it’s a little more consistent too, though it still needs a bit of polish.

Problems:

I’d quite like [short power] to stop play in the menus by calling ACTION_TREE_STOP, but unfortunately that only works for local files, not for the radio, which feels inconsistent. I’ve put in a feature request; http://forums.rockbox.org/index.php?topic=25657.0

The recording screen isn’t very consistent with the rest of the keymap - you can press [left] or [home] to get back to the menu, and [short power] and [right] both open the recording menu. This seems to be a peculiarity of the way the recording screen is designed, though I’ll try to improve it.

There is a ‘glitch’ in that when you press [long home] deep in the menus, it’ll sometimes jump through another menu before dropping back to the WPS / Radio screen.

Some users prefer to have a free button with which to turn the backlight back on - they are seemingly used to using [short down], which is bound to playlist here. However, if they don’t set the WPS hotkey, they’ll still have a ‘functionless’ button, so no functionality is lost.

I haven’t touched the HID part at all, because I have no clue what it does…

Details of major changes:
WPS:
[Long up] Pitch screen
[Short down] Playlist screen
[Long down] Quick screen
[Short home] Hotkey
[Long home] Stop

Pitch screen:
[Short select] Cycle mode
[Long select] Reset

Recording screen: (troublesome)
[Short select] Start / pause
[Short left] / [Short home] New file / exit
[Short right] / [Short power] Recording menu
[Volume] Adjust settings

Radio screen:
[Short select] Scan / search
[Long select] Presets
[Short down] Radio menu

Built against r2799. All comments and suggestions welcome, and thanks for reading.

This patch adds a new playback option, Pause Between Tracks. It pauses the playback automatically after each track, and the user must press Play to play the next.

This is useful for e.g dance classes, sound effects etc.

There is a noticeable lag in the simulator, where it starts the playback of the next song before pausing, but who cares? It seems to work fine on the target anyway.

Try it!

This has been (slightly) discussed before, but this is a new take on the matter, not a repeat of  FS#10683 .

With this patch applied, the following functionality is recognised with the hold switch in place:

On any list/menu screen or the while playing screen;
pressing MINUS decreases volume by one,
pressing PLUS increases volume by one,
pressing MENU switches between Play and Pause,
holding MINUS skips back a track,
holding PLUS skips forward a track,
holding MENU advances to the next folder.

I feel that anybody using a Cowon D2 will find this functionality essential, not only because it is present in the original firmware, but because it is necessary for in-pocket operation.
With a small DAP like this, with tactile buttons as well as a touch screen, it makes sense to maximize convenience.

I have added as much functionality as I could without requiring pressing multiple buttons at once. I have made several similar patches and built them for members on the iAudiophile forums, and this configuration has consistently been the most popular.

I welcome any comments/suggestions.

Amend the sleep timeout behaviour to pause when the timeout matures.

This allows the idle timeout to power off the player if it remains untouched, or the sleep / pause timeout to recycle if the user unpauses before idle timeout kicks in.

This is a beginning of support for line out and dock connection detection for the e200v2 (and possibly fuze).

The first patch enables line out in as3514.c. Line out is always enabled at this point, so battery life may suffer. Line out volume is set to 0dB and does not change unless the volume is set below -40dB at which point the DAC volume begins to decrease. This patch does not support as3525v2 at this time.

The second patch detects a connection to a dock on e200v2 (and possibly Fuze) and prevents switching to USB mode and rebooting to the OF. For this to work properly, you need to have Rockbox already booted. There is no need to press any button on connection. If a normal USB cable is attached, the OF will be booted.

TODO:
1. Only enable line out when connected to a dock and disable line out when the dock is disconnected.
2. Provide support for additional as3525 and as3525v2 devices. Information on IO port changes when connecting a dock is needed for this.

this is a simple plugin called 'moonrock' which shows the phase of the
moon. It is not the most earthshatteringly original thing but nevertheless the effect is pretty nice. Hopefully someone else likes this!

For targets with CONFIG_RTC, it either shows a text description
or, for HAVE_LCD_BITMAP and at least greyscale targets, a (pre-calculated) picture of the moon. But only if the data file (moonrock.dat) is present and found in the apps/ directory. (it should be attached to this post, I hope it shows up here, as the file is 3MB). (time of the player is assumed to be GMT)

you can switch between picture and text with select button, and choose a new date with play (which does not change the internal clock).

The patche changes some small things in the api and in the bitmap reading routines to be able to do things easily.

This patch adds SubRip subtitle support to MPEG Player.
http://wiki.multimedia.cx/index.php?title=SubRip

Files need to have the same name as the video file with a “.srt” extension.

I know that the OSD rendering is not implement in a way that linuxstb and jhMikeS would like but I still wanted to post the patch here in case anyone felt like adapting it. (Current OSD only renders on top of the video area, it can be adapted to add other OSD channels … like display a seek bar, volume control, playback state, etc.)

Enjoy,

Edit: I’ve also added a timebar display (when changing the volume)

This patch allows the line out on the Sansa Fuze V2 to be enable/disabled by means of the existing Lineout poweroff setting (previously used on some iPods).

By assigning this setting to the quickscreen I can switch between headphones and lineout after plugging into the dock. Still no luck in finding out how to autodetect the dock.

I'm not 100% sure that re-using the "Lineout Poweroff" setting is the right thing to do here as it's not powering on/off the line-out - just switching between headphones and line out

Hi,

this patch, that takes some of the FS10494, improves dock detection and initialization.

It should correct the erratic behaviour on some hardware, and it also adds support for some remote buttons: menu, select, up_arrow and down_arrow.

The buttons arrow are not usable by now, even if they are defined. I tried severals things but i couldn't get it to work.

Any idea of which context I should use to use the button arrow to scroll through the main menu?

FingersOfRock is a DDR variant where by arrows pass over the screen, and the player must press the corresponding buttons in time.

I don’t know how to use the cpu boost, so if someone has some time, please boost when the game begins and un-boost when it finishes.

It is called FingersOfRock from: FretsOfFire and rockbox.

For more details on the source of inspiration:
http://en.wikipedia.org/wiki/Dance_Dance_Revolution

Starting from the daily build from mid August (can’t exactly say when, because I don’t play MIDIs so often), the MIDI playback on my iPod 5G 30GB sounds distorted, especially the Piano sample.

It sounds as if the higher frequencies are chopped of and instead replaced by “alias frequencies”. Maybe something has been messed up in the mixing routine concerning decimation filter / interpolation.

I am using the original patchset provided here at rockbox.org.

Maybe somebody could check this - thank you!

Keep up the great work!

This patch should apply to all ipods, but needs testing - on both a mixture of ipods and mixture of operating systems. I’ve tested it successfully on my Color with both Linux and Mac OS X.

Current SVN behaviour is to write some magic to the end of IRAM and reboot the ipod when a USB connection is detected. This causes the Apple bootloader to start the disk mode application which is stored in flash ROM.

This patch cuts out the reboot stage and uses rolo to start the disk mode application directly from flash - meaning the ipod enters disk mode almost immediately. This is done in a new rolo_load_rom() function which copies the image from ROM to RAM and then executes it.

Here is a preliminary patch for TV out on a 5th generation iPod. Play a BMP file and TV out will activate. NTSC is the default. If the file has 576 lines, the output will be in PAL. The image stays until another is loaded or TV output is disabled via the debug menu..

The following formats ought to work:
720×480, 24 bpp for NTSC
720×576, 24 bpp for PAL
Many programs including Windows Paint and ImageMagick convert can write such files. Other resolutions and bit depths may work. For example WPS background screens display properly but other WPS bitmaps don’t.

Known issues:
- More work needs to be done to integrate this with Rockbox. No, you cannot view the Rockbox interface, JPEGs or mpegplayer output yet.
- When the LCD is updated, there is a temporary disturbance on TV output
- http://en.wikipedia.org/wiki/Macrovision#Analog_copy_prevention is enabled. Yes, the hardware can disable it, but I haven’t figured out how to do that yet.
- The original firmware probably outputs images differently. It can load programs into the BCM which perform decoding there, and that is probably faster.

EXTM3U is a format based on the standard m3u format. It adds a comment line before filename in .m3u or .m3u8 file in the format of
#EXTINF:xxx,yyy
where xxx is track length in seconds, yyy is the title.

For more info, see: http://hanna.pyxidis.org/tech/m3u.html

Supporting EXTM3U format has several potential benefits:
1. Instead of displaying filenames, track title and length can easily be viewed when viewing playlist (currently I think there is a patch that does it by opening each file).
2. Length of playlist can be readily calculated by summing, which can have some interesting applications such as finding how much time is left in current playlist. (Currently this is not possible yet with this patch, but I’m still thinking of possible solutions).

Of course, you have to have playlists in EXTM3U format to get the benefits. There are widely available tools to generate EXTM3U or add information to existing normal m3u playlists. In the future I might add functionality to Rockbox to save EXTM3U playlists (only if database is enabled and ready) or a plugin.

The current patch is able to parse EXTM3U information and use it in playlist viewer. To see it work, you have to set your track display option in the playlist menu to display EXTM3U information; otherwise, filename will be displayed. Two display options are added: title only and title plus track length.

This patch should have very minimal impact on normal playlist usage. A parse function and a few booleans values to existing structures are added, but the parsed title and filename share the same buffer (since they won’t be displayed at the same time). Specifically, beside a quick initial reading of header to determine if a playlist is EXTM3U and a few boolean checks, current playlist parsing/viewing routines are not changed if playlist is not EXTM3U or EXTM3U information is not needed for display.

Enough of me babbling :D Here is the patch. I did some limited testing, so it probably is not foul-proof yet.

In my sansa Fuze v2 build 28208 when I insert some album to the playlist and after that I insert another album to the playlist I got this error massege:

Data abort

FSR 0x8

Problem found in versions r29044-110113 to r29143-110126. I could not test 3.7.1, because it did not recognize my 16 GB Transcend flash card (fixed in above versions).

At the beginning of tracks and during rebuffering of longer tracks there is a short humming sound (like a bumblebee) mixed with a fast sequence of random high frequency tones. The sound differs as a function of data format and content. It is very homogeneous with WAV tracks (only humming) and different with lossy and lossless codecs. The same file encoded with FLAC and AAC leads to different short distortions. It is only audible for tracks with initial silence or very dynamic content, for example classical music with quiet passages or audio books. With sensitive headphones, this can be quite annoying.

The original firmware does not show this behavior!

It only happens while reading from the SD card, not from the internal storage.

Initially I thought this might be a CPU throttling issue. But now I think it might also be related to the controller driver.

There is a thread on Hydrogenaudio with independent confirmations of the issue:

If I can provide any additional information to help, please let me know.

This patch adds fairly decent support for the sliderbar on the front of the iRiver H10 series players. This functionality is prominently displayed on the H10 wiki as something that is significant and missing.

With this patch the user can slide his finger over the slider to produce a scrolling effect. Or, they may also tap or hold down the upper or lower 30% of the slider for the older up/down behaviour with auto-repeat provided by the common code. This basically mimics the OF’s functionality.

The physical slider is very sensitive, so the values that come back from it are fairly spastic. I’ve attempted to tone down any wild behaviour, and I’ve added #defines in the patch that can be used to tune the behaviour. But frankly, even the user’s thumb size will affect what “good” values are. I believe what I have is good for the time being, but more tweaking may be necessary as time goes on.

I would like to change voice strings to make them sound better with a specific SAPI voice.

I don’t intend to change string in *.lang directly.
It should be done in voice.pl dinamically while building voice, shouldn’t it?

This is a preliminary patch to add the key maps needed to compile plugins for the android port. It is mostly complete.

You will need to change plugins=”yes” line 2790 of file /tools/configure but this breaks the sdl port.

Most plugins seem to work well some don’t, I have not tested all plugins yet but will start as soon I post this.

To
a section to tools/configure that defines plugins=”yes” for the android port and “no” for the sdl port

patch probably breaks some targets because of logo.c defaulting to a generic keymap which I changed “commented out” and added #error No keymaps defined! so the compiler will not just over look it. Let me know what breaks and I will try to fix it.

If LCD_SLEEP is put on the backlight queue immediatly after BACKLIGHT_ON, the LCD will go to sleep immediately after the backlight turns on. On the 5G iPod, the next backlight_on() call will wake it, but on some other targets it might not wake again.

For example, consider the following sequence of events:
1) backlight_on() is called, putting BACKLIGHT_ON on the queue
2) The LCD sleep timeout from the previous backlight shutoff puts LCD_SLEEP on the queue
3) BACKLIGHT_ON is received and the backlight is turned on. The call of backlight_lcd_sleep_countdown(false) does nothing about the LCD_SLEEP on the queue.
5) The LCD_SLEEP is received, putting the LCD to sleep again.

This patch causes LCD_SLEEP to be ignored by backlight_thread() when the backlight is on. It also removes a workaround from 5G iPod LCD sleep code.

This issue is theoretical and very improbable. I am not able to trigger this bug in r20774.

This patch resorts the v-array within mpc’s synthesis filter. Through this data is placed more locally for the performance critical function mpc_decoder_windowing_D() and allows ldm-usage in the asm’ed parts.

This first patch does work for simulation but not for ARM or CF builds. An update with more optimized ARM asm will follow, CF asm needs to be corrected by someone with knowledge on CF assembly.

The output is binary identical.

[EDIT: Attached patch for experimenting with AS3543 settings.]

When playing back audio on a Sansa ClipV2 player, there is a regular background noise that’s audible with sensitive headphones and that’s quite annoying during quite music passages. The background noise is a hissing sound that repeats about 4 times per second. The noise can be heard when there is no disk activity and even at very low volume or when playback is muted. It stops as soon as audio is paused.

The noise is not present in the original firmware (OF).

This is a long-known issue, but hasn’t been formally tracked before. It is related to FS#11907, but different in that the background noise is present when there’s no disk (SD) activity. However, I did have the impression that disk activity intensifies the noise.

This item serves to collect the various approaches people have tried to eliminate the noise, and ideas for future exploration.

I ran a series of experiments on the assumption that the audio hardware is misconfigured is some way. I worked through various settings of the AS3543 component based on its datasheet. Here is what I have tried; but nothing helped to eliminate the noise:

* Higher-quality audio settings as proposed in  FS#11304  (AUDIOSET2_HPH_QUALITY_HIGH,
Disabled DAC gain control
Bypassed mixer and disabled mixer gain control (HPH_OUT_R_HP_OUT_DAC, AUDIOSET2_AGC_off,
Mute SDI data
Enable and control DAC attenuation
Disable common mode buffer (phantom ground)
Disabled various unused mixer components (AUDIOSET3_MICMIX_off, AUDIOSET3_ADCMIX_off,
Used external clock source for DAC
Enable headphone detection
Resetting all reserved audio registers to 0

[EDIT: I have attached a patch that allows experimenting with these settings by uncommenting the relevant source lines at compile time or extending the provided debug function to toggle the setting at run time.]

Possible next steps (suggested by various people on IRC):

* As the noise is not present on the other AMSv2 targets (Clip+, FuzeV2), a dump of the AS3543 settings (as3514_regs[] array) on these targets would be helpful. I have attached a patch that adds a debug-menu function for doing this (needs a logf build).

* Someone with a JTAG could read the AS3543 configuration set by the OF.

* The issue could be unrelated to the AS3543; it could be a power-management or frequency-scaling issue.

Also attached: A dump of as3514_regs[] (logf.txt; all values in
I’ve removed the patch to dump these settings; see a later comment in this task for a more up-to-date patch to do this.]

Other ideas?

The attached patch implements sinc based resampling in rockbox.
I have only tested it stand-alone so far (i.e. the code outside of rockbox – I am waiting for a replacement for my broken android phone to test it there).
There is (of course) quite some room for improvement.
Things which could be improved:
- buffer handling
- calculate the correct sinc spanning the whole table for downsampling. Then the downsampling and upsampling code would be the same (no need for sinc_increment, saving some additions). Also the result would be more accurate resampling.
- Save some memory by always calculating the correct sinc and putting it into resample_data. Would need to use fp_sincos() for that.
- Save some more memory by taking advantage of sinc's symmetry, only storing half of it in the table.

I know that I'm breaking the coding-style by using more than 80 chars in some lines. I will fix that when I have time. I wanted to get this code finally out to get some feedback after it sitting for two weeks (basically unchanged) on my HD.

This patch adds a new codec that playbacks ZX Spectrum .tap files. Created against trunk (revision 31187)

When using the H300 non-lcd remote to turn on the player (iriver H340) I get the following error message “hold switch on, power off…” (the hold switch is not on).
