Rockbox

This patch adds to the simulator the ability to simulate usb on a Linux host.
To do this, you'll need to download, build and install a device driver. You can download it here:
http://sourceforge.net/projects/usb-vhci/files/ Just download the "linux kernel module". See install instruction in it but it's make && make install. Of course you'll need root rights. There also a wiki about it (http://sourceforge.net/apps/mediawiki/usb-vhci/index.php?title=Main_Page)

Now to have usb simulation works correctly you'll of course need to load the driver
modprobe vhci-hcd
And you'll probably need to edit the access rights of the device control device:
violent example: chmod 0666 /dev/vhci-ctrl
other example: chown root:<myself> /dev/vhci-ctrl
Or you can add a udev rule if you can make this work.

You can then run the simulator normally (note the the detection is at runtime so you don't need to have it work before launching the simulator).
Press 'u' to simulate usb insertion and 'u' once more the simulate usb removal.

Some miscellaneous remarks:
-the patch enables usb hid but for some reasons it doesn't work in main menu. However, the remote_control plugins works
-the patch enables usbserial which of no interest here but a way to test bulk transfers
-the patch DOESN'T enable usbstorage because storage simulation is a stub currently.

If it doesn't work, you can still uncomment this line in usb-drc.c:
/*#define USB_VHCI_DRIVER_DEBUG*/
And this line in usb-core.c:
/*#define LOGF_ENABLE*/
But beware ! Your console will end up full of obscure messages.

I'm particulary interested in compile feedback under Windows and OSX.
And of course I'm interested in working feedback ranging from device detection to working state (HID and usbserial) for example.

This flyspray task will hold the development of a potential usb audio driver for rockbox.
It will also serve for the development of the isochronous transfer support support in usb code.

This patchs modifies the simulator so that it can emulate the storage layer. More preciserly, it enables all the storage code and simply redirect all storage_{read,write, …} to a file. This way, all fs functions used are the one of rockbox, which allows to debug the FAT code for example.

To run this, apply the patch and modify the makefile to add this: -DROCKBOX_SIMULATE_STORAGE_LAYER
to the line:
export GCCOPTS=….

When running the simulator, it expects to read from file simdisk.raw. You can change this by using the –root option:
./rockboxui –root <file>

The code doesn’t work for me, FAT code seems to choke on something for now, I’m not sure why.

A mixed RTL with LTR text appears in a missed order not conforming to bidi logical to visual algorithm of unicdoe.

Implementation is ready in bidi_l2v() , but the “orientation” parameter is hardcoded and passed as “1” always

A suggested solution is either pass “orientation” as 0 for any RTL text, or tie the orientation parameter with the “alignment” option of the text viewer.

- write a word like “مسمار” in a text file, or just use the word as the file name

- the last character “ر” will appear as the first one like this: “رمسما”

- this bug appeared only since r26019

- when reverting to r26018 the bug won’t show up

- for some combination of letters like “دليل” the issue happens for the last 2 characters

- for some other words the problem doesn’t happen at all

- the only common case is that this happens only with last word in a line appearing on the viewport

This patch which is a small change in bidi.c contributes with the diacritics patch (http://www.rockbox.org/tracker/task/10720) to fix the diacritized Arabic text joining problem

The (software-)equalizer is adding high noises to the playback.

I made a recording, the first part with eq enabled the second one with disabled equalizer.

I could also make a test on my older H110, on which I never used the sw-eq though.

This patch adds more touchpad functionality to the game. It is possible to play by selecting the pieces directly instead of using the simulated buttons.
The changes are:
1. Added touchpad_get_mode to the plugin API.
2. Added menu entry for touchpad devices the switch between button mode and direct mode.
3. The user’s default touchpad mode is save during start-up of the plugin and restored after quitting.
4. The direct input mode is set only during the game (not in menu or view).
5. Extended play loop to handle BUTTON_TOUCHPAD event.
6. A piece is selected by clicking twice on it, moving is also done by clicking the target field twice.

The patch has been tested on the COWON D2 and also seems to compile fine for devices w/o touchpad. The patch has been created with

svn diff -x -w apps > touch_chess.diff

in the root directory. It would be nice if someone could test this (also on non-touchpad devices) and give me some feedback (bugs and improvements).

This is the game Squarebloxx. It works on Color-LCDs only because colors are an essential part of the game. I tested it in the Simulator for all the color Boxes. I also tested it on my H340.
In the game you have to mark parts of an array of tiles. If the tiles in the corners of the mark are the same color, the marked area is done. If all tiles are done the level is finished.
Please give me feedback and report bugs.

Thanks Krush

With r30907 (and also back to at least r30809 which I tested as well) I experience unneeded mass storage accesses on my iPod nano2G. I do not see this effect on my iPod Video.

Use case:
- Create a playlist from either DB or file browser
- Let buffering finish
- Skip forward track by track
(I use mpc/mp3/aac with embedded album art.)

Effect seen: For some skips I see short flash accesses (much shorter than full rebuffering).

This only happens if dircache is off. With activated dircache this effect is gone.

As such mass storage accesses are severely impacting the battery runtime on HDD targets I hope we get this figured out before v3.10.

This patch is a proof-of-concept for an adaptive runtime estimation.

Reason to implement such behaviour is that different user settings and user behaviour have large impact to the power consumption and – as a result – to the runtime. E.g. disabling LCD will save lots of power, but some users do not want to disable the LCD to keep readability in daylight.
This patch therefor adapts the estimation of runcurrent() based upon real measurements of the current consumption. The algorithm starts with a default (CURRENT_NORMAL which is defined in the config-file of each player) and uses a weighting scheme with a large time constant to adapt the estimation of the current consumption. The time constant is 1024, which should equal ~20 minutes as the runcurrent()-function is called once per second. With a smaller time constant the runtime estimation is “pumping” too much when the HDD is active.

This first version is just a hard coded experimental solution. Nevertheless something like an actual_current()-function can be implemented for each player in its own powermgmt-file. Players with capability to read the current will return this measured real current, all others still return the fixed default CURRENT_NORMAL.

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.

If Rockbox is connected via USB with no sd card inserted and it is inserted, it offers the OS to mount the new drive.
If the sd card is removed and reinsterted again, it fails to offer and recognize it.

I could locate the problem in firmware/usbstack/usb_storage.c in the line

if(inserted && check_disk_present(IF_MD(volume))) {

after reinserting the card, check_disk_present fails to return true, so this check fails and the card isn't recognized anymore.

Hello World :)
Attached is a VBR WMA music file, which fails to play correctly on my “RockPod” iPod Nano.
The same file decodes perfectly using the latest ffmpeg build.
Therefore I can only assume there is something about this file which triggers a bug in the Rockbox-specific WMA decoder.
Also attached is a microphone recording of the sound which comes out of my iPod when Rockbox attempts to play the faulty WMA.

I have over 3000 WMA tracks, all encoded using an identical method, all of which will not play correctly in rock box, so if you would like any more examples, or information, please ask.

Thanks for all your help :)
(If there is any way I can help debug/update the code for the wma decoder, please let me know where to start, I understand the C source code pretty well)

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.

rockbox 3.5: ipod doesn’t recognize the connection of usb. i understand that rockbox doesn’t support usb on a 3G ipod, but it would be nice to boot into disk-mode like it does for firewire.

charging isn’t monitored on ipod 3G. it just goes up to 100% very quickly and stays there.

if i format the clip+'s microsd card to contain a DOS partition table, then the vfat formatted partition is not recognized.

if i format the sd card with a vfat fs starting at the first block, then the fs is recognized by rockbox.

** if i then reformat the sd card with a partition table like above, then the second fs i created is still recognized by rockbox, even though the first 512 bytes or so have been clobbered. the result is that rb and my laptop see different fs structures, and clobber each other's metadata, causing corrupt file systems.

the work-around is to dd if=/dev/zero the beginning of the sd card and format without partitions.

i kindly request that rb support dos, or some other, partition table, and maybe that rb doesn't mount fs'es which appear to be clobbered by a partition table. one problem with this change is that some people may be using a clobbered fs without knowing. with such a patch, they could end up seeing a corrupt fs instead.

i don't consider this very high priority. thanks for the awesome firmware!

Add support for two new scroll styles, STYLE_NODRAW and STYLE_CUSTOM, with STYLE_CUSTOM causing the draw to be done via a hook (set with lcd_set_style_hook). lcd_puts_stroll_style_offset also returns a struct scrollinfo pointer. This may be used in conjunction with STYLE_NODRAW to redraw the scrolling text in a plugin which draws other graphics to the same part of the screen, by drawing the text using the offset in the struct scrollinfo after the background graphics have been drawn. My latest patch from  FS#4817  is required, as it consolidates styled text drawing in one function, making it easier to replace the normal draw with a call to the hook, and reducing the binsize impact of this feature as well.

Support for core text scrolling in PictureFlow plugin to follow .

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 patch will add a setting, called "Scroll Bar Border", which will determine whether menus / lists will have scrollbars with borders or not.

The default value for this setting is "yes", so that it matches previous behavior.

   I've update my ipod nano 2G to r23629. I found the clickweel would remember the last point my finger leave. And next when I touch the clickwheel, it will make a farward/backward move according to the last point I left, even click the button. Now it is not convenient to type a word with the keyboard inside or setting.
   And my Mac doesn't launch my ipod when I connect my ipod with USB until I change to disk mode. Seems that the USB driver doesn't work.

URGENT/HIGH PRIORITY: Rockbox Firmware 3.7 installed with iRiver H300 1.29J.

Charging when in Rockbox mode (player switched on):

When Rockbox is running and the charger is plugged in, Rockbox can be seen charging the battery in the top left hand corner. When it is fully charged, it shows a full battery.

Charging when iRiver is powered off (player switched off):

When the charger is plugged in, the iRiver begins charging in Original Firmware mode. This is okay as the player charges correctly until Complete.

Booting into OF mode, shows a full battery charge so I can be sure it is fully charged.

However, boot back into Rockbox mode and Rockbox seems to be misreporting the battery charge as depleted - I say misreporting because at this point I know it is actually full/complete. (Booting back into OF mode would also confirm again at this point that there is indeed a full battery charge).

But run Rockbox 3.7 and after a few minutes, a false message - "Low Battery - Shutting Down" appears, after which Rockbox powers off.

I know this is inccorect, because if the battery was so low in OF, the iRiver OF would not even allow you to attempt to power back on (instead it would display a "Low Battery" picture on the display), but I can boot back into OF mode easily with no problems even after this message from Rockbox, again the OF shows a full battery and I can run it for hours with no problem so I know somewhere here there must be a miscommunication/misreading from the battery charge to the Rockbox 3.7 firmware.

Have tested this a number of times to ensure it is a fault and yes it presents itself everytime.

I have experienced a fade in reception with my sansa e260. If I tune to a station, the longer I listen, the more static becomes present until the station is all static. I have found however that if I navigate to another station and go back. The station is clear again. This does not happen on the original firmware and does not seem to be location specific.

So the firmware seems to be seeing a degrading signal, but the signal is not actually degrading. Or perhaps the frequency to which the FM tuner is tuned, begins to deviate until it reaches a point of all static, even though the tuner still displays the original frequency.

Thanks.

Stereo width of >0% can cause stutter in the form of an audible click.

Bypassed by setting stereo width of 0% or monophonic channel configuration.

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)

Expected sorting by artist name, then by album and then by track number, but now all songs by all artists sorting by track names in alphabetical order.

- What behaviour you are seeing

Rockbox 17612-080523 on an iRiver H340 skips entire tracks, and also skips within tracks, when the battery level falls below 30%

- What behaviour you expected

No skipping.

- How to reproduce the bug

Allow the battery level to fall below 30% and start playing a directory of files. Some files will be skipped, some files will have parts skipped in the middle.

- The SVN revision you are using and if possible the particular SVN revision in which you think the bug was introduced.

17612-080523, no idea when the bug started.

If you need any further info on this bug, please ask and I’ll give more details. I have no other hardware to test whether this behaviour occurs on other Rockbox platforms.

screen, navigation is basically impossible.

The config caused the iPod to appear frozen (frozen screen) after bootup. The iPod would boot, show the normal boot screen and then created a boot screen mixed with theme settings. Picture: http://imgur.com/E4srA the iPod refuse and refused to mount.

Fix:
1: Boot into recovery diskmode
2: Remove conflicting config.cfg
3: Reboot into normal mode

Playing APE 24/44.1 with harsh noise in different parts of the track. If you decode APE file to WAV using the codec console, then there are no problems. So the matter is in the player’s APE decoder.

At 24/48 everything is fine.

This patch adds a frequency response graph below the equalizer's controls, making it an EQ that is actually "graphical".

I'm still not sure about the accuracy of the represented curve, in particular the Q factor on the peaking filters seems to have an effect opposite to the expected, though the equations are taken from the same "audio EQ cookbook" the equalizer is based on, any help is appreciated!

The user interface is still incomplete, I want to add proper tags on the axes and bars. I also thought about re-enabling the theme on this screen (why is it disabled?) and change the behavior of the "right" button, making it consistent with other menus.

Rockboy data aborts on menu key press, when the srceen is rotated left and image is stretched across the whole srceen. Also no matter what key is mapped to the menu entry it will still fail.

It never fails when aspect ratio is maintained with scale or when not scaled at all, and never aborts when rotated right or not at all.

Only four files even mention rotate in the apps/plugins/rockboy/ directory “lcd.c menu.c rockmacros.h and sys_rockbox.c”

Sometimes the failure does not happen and reaching the menu is possible, but the rockboy option file may get written and not allow the user back into the menu later to change the rotate option back. When this happens the option file must be edited or erased to make rockboy work again normally.

Game Brickmania bug:
The ball just disappears (often on Level 2, but maybe on others). Ball will just usually go to the top corner and not “bounce” back, but the game acts as if a ball is still alive (doesn’t register a lost ball) though there is no further movement on screen. I just have to quit the game.

The ball doesn’t bounce back. No further ball is issued. It just disappears and I can’t interact w/ the game anymore due to no active ball.

FIRST APPEARED: This began a few weeks ago (sorry I can’t be more specific), but has persisted in several “daily build” updates I’ve done and is in the current build I just installed.

REPRODUCIBLE: I reproduce the bug each time I just play through Brickmania. It generally happens in level 2 of the game though it may happen in subsequent levels– I don’t get through to them to see.

I’ve installed with rbuitil and manually, same thing happens. I have 2 different V1 e200s and it happens on both of them.

Thanks for all your work on the great Rockbox.

I’ve been reliably informed that Rockbox should stop scrolling when it gets to the bottom or top of a menu, only to wrap around when you initiate a new scrolling gesture. On a 2nd Generation iPod, however, it just keeps scrolling.

See http://bertram.bourdrez.org/buggyrockbox.avi (the video is recorded with an old Rockbox, but 3.2-090323 does the same thing)

Also, the bug tracking system is overcomplicated. I have to register an account?!
“Why the hell should *I* set up an account? It’s not like any bugs will be assigned to me or anything. Just store my e-mail address and move on. It’s completely fucking bogus that I should have to go digging through my mail for confirmation passwords.” (http://zork.net/~sneakums/fortunes/gar/215)

Then I have to click a link with a magic number in it *as well as* having to enter a confirmation code from the same email (!?) and then when I’ve finished, I’m not even logged in! I have to log in with the same password I just set! Can’t it just set a cookie?

Current developer build (2012-06-10), on Sansa Clip Zip
While audio is playing, connecting USB and disconnecting it again causes a splash with message “Error accessing playlist control file”. Sometimes followed by a hard crash (like undefined instruction).

Initial analysis shows that the problem occurs in playlist.c:get_filename. An lseek in the playlist control file fails. This lseek fails because the file descriptor (fd) was closed during USB connection. On receiving a SYS_USB_CONNECTED event in apps/misc.c, function system_flush() calls playlist_shutdown().
So the playlist subsystem seems to have been de-initialised during USB connect, but not completely, causing problems when the playlist subsystem resumes during USB disconnect.

This is reproducible on the simulator.

Version: 3.13

Variable ‘tmp’ on line 565 is possibly not initialised (found by cppcheck).

The Idle Poweroff only reboots my 1G iPod. I assume it should power it off or put it into a power saving mode. This forces it to use up the battery faster then normal unless I set the Hold button to boot into the iPod firmware to do a proper suspend when Rockbox reboots.

General:
The trainer works with (three) cardboxes. Known cards will be moved from left to right to the next box, unknown to the first. You have finished the test if all cards are in the last box. The actual filling status of the boxes is graphically shown.

How the user handles the trainer during the test:
- a word is displayed
- the user thinks about the translation
- after pressing a button the solution is displayed
- the user decides by pressing the forward or backward button if he was right or wrong
- according the selection the card is shifted to the next box or to the first

Options:
- select vocabulary file
- reset (statistic) of vacabulary file
- change direction of inquiry
- display comment on/off
- colour settings

Vocabulary files:

The vocabulary is stored in files in the following format:
word1;word2;comment (optional)

Example:
lernen;to learn;verb

File format:
Maximum length of words:50
Maximum number of lines:500
File format: UTF-8

The manual says in page 31 chapter 4.3.3. that you can get to the Playlist Viewer Settings from the Playlist Viewer Menu (which should probably be named Playlist Viewer Context Menu), but there is no such entry on the actual player. Just via the settings menu from the main menu.
