c72824786a Initial, work-in-progress, version of a WMA codec using Michael Giacomelli's fixed-point and malloc-less WMA decoder (based on the ffmpeg WMA decoder from early 2006, and also building on the work started by Paul Jones). The codec itself and the ASF parsing code were written by me, inspired by the ASF parser in libasf. Current performance is around 400% realtime on gigabeat, 100% realtime on PP and 20% realtime on Coldfire.

9a011f3a80 Clean up the codec API - remove all unused (and in many cases inappropriate) functions, move functions used only by encoders into the HAVE_RECORDING part of the API and document the reasons for the more unexpected functions being present.

26d242ae65 General housekeeping: Make plugin buffer functions take size_t * instead of int * to match the parameter type of the buffer functions called in the core. Get rid of unsafe int * <==> size_t * casting. Use ssize_t where int was used and size_t where unsigned int was used in the buffer calls to not alter signedness in the plugins. No API version change since it should only be an issue for 64-bit sim builds.

82f9056988 Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly.

598629c3bf SWCODEC Recording Codecs: Fix problems with hanging recording screen (chiefly on x5) when no voice file present and source is not FMRadio. Caused by extra audio stops causing encoder to unload prematurely. Fix is to have separate stop flags for each codec type to prevent collisions. Also now safe to plug into USB when recording and encoder will stay loaded and not be stopped by the call to audio_stop_playback. Additional discovery: playback will not be able to restart after a USB plug during recording. Probably an old bug. I recommend in the future that recording have higher priority on system resources than playback and playback be denied access explicitly if recording requires them. Codec API becomes incompatible so do full updates.

d4e904bf35 SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update.

97f369a587 SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile.

aba6ca0881 Fix resampling clicking as much as possible at the moment. 1) Upsampling clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output.

80da8b141c FS#6357, patch 1: let iramcopy and bss share the same space in codecs and 
plugins. Currently, in case of plugins using IRAM bss is cleared twice,
once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only
during codec initialization. Also, removed double variables in codecs
storing a pointer to codec_api.

0f5cb94aa4 Big Patch adds primarily: Samplerate and format selection to recording for SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs.

a85044bf9e New scheduler, with priorities for swcodec platforms. Frequent task 
switching should be more efficient and tasks are stored in linked
lists to eliminate unnecessary task switching to improve performance.
Audio should no longer skip on swcodec targets caused by too CPU
hungry UI thread or background threads.

* Linked list instead of static array buffer pointers
* Variable sized chunks
* Improved mix handling
* Reduction in duplicated code
* Reduced IRAM usage w/o sacrificing performance
* Converted to almost entirely unsigned math
* Add pause function to reduce pcm_* exposure to playback.

Peakmeter stops hogging the CPU when the disk is spinning; this is enough to avoid the performance problem when saving data. * Optimisations, code cleanup and code policeing. * (iriver) Reduced CPU load of peakmeter by not calculating excessive overlaps. ** Bumped config block version, so save your settings before upgrading.
