Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29785 a1c6a512-1295-4272-9138-f99709370657

Get track change notification in on the actual last buffer insert of the track because now audio simply waits for a track change notify from PCM on the last track and it must be sent reliably.

* SWCODEC Recording Codecs: Fix problems with hanging recording screen ↵Michael Sevakis2007-03-04
| | | | | | (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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12579 a1c6a512-1295-4272-9138-f99709370657

* Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis2006-11-06
| | | | | | 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11452 a1c6a512-1295-4272-9138-f99709370657
