Rockbox

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

The setting works similar to the autoresume dirs: Directories are seperated
by colon, e.g. "/Music:/Podcasts". Default is "/sdcard" on android, "/" on
all other targets.

A maximum of 8 dirs can be selected, the setting cannot be longer than 80 chars.

Note: There's one problem. If you specifiy "/Music:/" (or any folder and one if its parents afterwards), then /Music is scanned twice. It's tricky to fix, and I'm not sure if it's worth it. This does not happen for "/:/Music" as it can be detected more easily in this order (and this is already implemented).

This patch adds a %ch tag that returns the number of channels in the current file.

Unfortunately, the large majority of codecs don't fill in this field in struct mp3entry. In the codecs covered by the rockbox testfiles collection, only atrac, cook and tta actually work.

I don't think it makes much sense to commit this with so few supported codecs, so help is appreciated on the codec side of things

Rockbox WebOS app.

Built on r31467, 32/64-bit Ubuntu 11.10, running on a 32GB Touchpad

Directions (only tested on the above):

* Install WebOS PDK: https://developer.palm.com/content/resources/develop/sdk_pdk_download.html

* Install platform-native libsdl-dev if you haven't already. Only needed to pass configuration check as the PDK doesn't properly install staging sdl-config for some reason.

* Apply patch (patch -p0 < filename.patch)

* cd webos

* ../tools/configure, select WebOS target (206)

* make && make install && sh ./buildpkg.sh

Notes:

* This is one big hack – I fudged just about everything in /firmware (how the target system works is still not altogether clear to me) and piggybacked a lot of this off of the SDL target. Mostly in the interest of getting it to run without adding ifdefs all over the place. Obviously we'll want to be more methodical and thorough about exactly which changes need to go where moving forward.

* The Touchpad's SDL video implementation appears to adjust orientation and scale output to fit within 1024x768 as best as possible. This means that a 800x480 build will appear in landscape mode, letterboxed, while a 320x480 will appear in portrait mode, pillarboxed. The device itself automatically orients to landscape – meaning, if you're in a portrait resolution and then you exit, everything will initially be sideways – but that doesn't affect input. Scaling routines are noticeably slow.

* I tried building this as a hybrid Enyo/PDK (window mgr friendly) app but had some problems with the native part failing to execute at SDL_Init. So for now no backgrounding or notification bar.

* Make scripts use the ARM compilers installed with the PDK. I'm wondering though if this is superfluous given that the Rockbox toolchain also supports ARM7. I did try exposing some of the ARM-specific assembly but the compilation failed with the PDK compiler.

External/USB adapters are not correctly detected on my Classic 80Gb, this patch detects it so car mode functionality now works, also the iPod is powered-up when USB cable is inserted.

The function power_input_status() returns USB charger when both external and USB chargers are present. It is possible to detect the external adapter when USB cable is plugged but it is necesary to poll the PMU (not IRQ safe), and i think this information is not currently used at all.

The location for recordings can be set, but the only way to see the current value for the setting is to look into the config file. The patch adds a note stating that to the manual.

Also, there is a known bug ( FS#12517 ,  FS#12500 ) preventing saving the recorded files in the root directory (maybe this applies only to some targets, not all). The patch adds a warning about that.

The iPod Classic Cirrus CS42L55 DAC+amp chip is specified to output audio up to +12dB versus the reference level (0.775V RMS) and the current Rockbox driver implements this accordingly (note that the OF limits the amplification to a lower level).

However, any amplification above +3dB applied to a 0dB signal results in serious clipping errors, the sound being distorted (oscilloscope measurements attached). This is not a surprise, given that +12dB translates in over 8V peak-to-peak output, way above what the iPod is capable of with its 3.7V battery.

Distortions aside, +12dB can be overkill for most of the earphones (depending on the sensitivity) and not a very pleasant experience. If you put the iPod in your pocket and forget to lock it you may experience this frequently.

In practice not all tracks have peaks reaching the 0dB level (actually nowadays this is quite common given the "loudness war"). To provide some room for additional amplification when needed, I found the +6dB limit to be a good compromise.

I know keymap changes can be a difficult topic, this one however is just a small change - which, I hope, improves usability of Clip players quite a bit.

I just swapped the behavior of two functions when browsing lists: short press on the power button returns to WPS, and pressing menu + center stops playback while in lists. Return to WPS is arguably the much more often used functionality of the two, and this change makes it easier to do that.

Android:
The Notification bar which use "Remoteviews" may be not suitable for some ICS Roms (see Attachment).
So I change the Remoteviews to "Notification.setLatestEventInfo" to display the track information.

The patch may have some offsets.

I am working on adding album art support for FLAC and Ogg files. FLAC looks straightfoward, but there is a design problem with Ogg.

https://wiki.xiph.org/VorbisComment#Cover_art

The struct containing the image and associated data is base64 encoded. I can't just set id3→albumart.pos to a location in the file like all other supported album art formats (and FLAC). Obivously I could allocate memory for the decoded base64 data, but it would have to be deallocated later to prevent a leak.

On IRC, nick_p suggested: "how about adding a new id3 struct element id3→albumart.base64_encoded=true and decoding it when needed on the fly?" This sounds like a good idea, with one issue: it's not the album art alone that is base64 encoded, but the data struct described here:

http://flac.sourceforge.net/format.html#metadata_block_picture

I can test to see if I can parse the beginning of the base64 block, then set the pos pointer to the middle of of the block (with the id3 struct addition) and see if it will still decode.

Hi there,

  this is a WIP plugin that I wrote last year.  It plays amiga music using the UADE library.
  You can find more about it here: http://zakalwe.fi/uade/

  I'm a bit new to git so please forgive me for not uploading a proper patch.

  To test the plugin, simply copy the bitmap and rockuade folders to the plugins folder in
  rockbox sources.  And you have to extract the data.zip file in the .rockbox folder.

  I'm not going to work on this anymore, so I decided to upload it here, and hope someone
  can make a proper patch and maybe some dev would be interested in testing it, make 
  the necessary changes and upload an stable release.

  Please read the README file for some additional info about the plugin.

  Tested on:    samsungypr0, fuze+, fuzev2

Hi there,

  this is another WIP plugin that I wrote last year.  It plays videogame streamed music
  using the vgmstream library. Original homepage here:
  sourceforge.net/projects/vgmstream/

  I'm a bit new to git so please forgive me for not uploading a proper patch.

  To test the plugin, simply copy the rockstream folder to the plugins folder in
  rockbox sources.  And you have to extract the data.zip file in the .rockbox folder.

  The formats.db found in data.zip is basically a list with all vgmstream supported
  extensions (at least "all" by the time I wrote the plugin).  You can add  or remove 
  new or unwanted extensions there.  The plugin will only handle the extensions found
  in the formats.db.

  Currently the plugin works as a viewer plugin, and there is only one extension associated
  with the plugin in viewers.config for testing purposes, but you can always use the 
  'open with' option from rockbox.  Once you open a file the plugin will parse all supported
  files found in the same folder.

  The vgmstream project is updated quite often, if someone wants to
  update the core library, I believe that would be very easy, since I only changed a couple
  of things to it.

  I'm not going to work on this anymore, so I decided to upload it here, and hope someone
  can make a proper patch and maybe some dev would be interested in testing it, make 
  the necessary changes and upload an stable release.

  As a last comment, I have only tested the plugin in the simulator, samsungypr0, fuze+
  and ipod nano. It only worked in the simulator and samsungypr0, so hope someone can 
  fix that.

  Please read the README file for some additional info about the plugin.

  Working on:  simulator and samsungypr0

I'm decided to make myself useful today and hammered out most of the rest the code needed to move http://www.rockbox.org/tracker/6048 along.
I'm starting a new entry since the old one is closed.
I'm hosting all the work I do at http://foolsh.no-ip.org/projects/atari2600/wiki/Wiki

2600box Plugin

* Added the .make file
* Added keymaps for most color targets
* Added to viewer.config loads *.bin files
* Fixed screen resizing for smaller screen targets
* Compiles against HEAD/master

I'm still testing sim builds at the moment.

There is some bad news, it crashes in the sims after a minute or two, and the buttons on my fuze+ don't work for some unknown reason but they do in the sim.

Everything else is looking pretty good. I'd like to hear back from people who have real hardware and can test the keymaps.

This patch changes the frequency range when selecting "Region: Other" for the FM radio:

With this patch, the "full range" from 76 MHz to 108 MHz, in 0.05 MHz steps, is available when selecting the "Other" region.

I noticed that the playlist seems to become one item shorter when I shuffle it, using the latest Git master branch (commit 70d57080) on a Sansa Clip+.

Steps to reproduce:
1. Clear the playlist by pressing Stop (power button)
2. Add a small number of tracks to the playlist
3. Shuffle the playlist (playlist view, menu, Shuffle)
4. Observe that playlist is one item shorter than before

I tracked the reason for this down, and attach a patch. This isn't a "proper" fix, and is a bit hacky, but it does illustrate what causes the problem.

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 would like to run my iPod with its keypad locked all the time, thus I wrote a little patch to an option to disable the settings reset during startup regardless of the hold button's position.

You will find the patch attached to this message. I'm not entirely convinced by the name of the new option (or my wording in general) so if you have a better idea, feel free to rename things.

In the "Scroll bar width" screen, the value used to show the width selected is the previous one, not the current one. The first value change has no effect.
Anyway it seems that the right value is stored: if you select a value and exit by the screen, when you re-enter in it, the width is correct.

Priority low.

Referred to r22406.

The OF ide_power_enable routine sets some GPIO _ENABLE bits to zero when enabling power and sets them to 1 when disabling power. This makes a difference of about 1 in 4066_ISTAT ( FS#9728 ) on my 30 gig iPod, which probably means saving about 0.75 mA. But if 1 is enable, why does enabling pins save power?
