ce89a2745c Woops. Upon examining the diffs again I find I shouldn't have deleted that one yield() from the a52 codec.

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.

bbef13eddf SWCODEC: Stop clicks between tracks when resampler is active by only switching the DSP frequency and not resetting the resampler at track boundaries. Will make sure DSP is correctly flushed at dicontinuities but don't hear any problems currently.

354770088e Re-enable the currently unused and broken dithering and noise shaping code already in Rockbox, and make it a user option instead of a codec-controlled option. The majority of people probably will not even hear any difference with this enabled, but feedback is welcome. Save your settings!

ebadcc633a Put new_track on the codec_api, and use it instead of the reload_codec variable in most places. Should help with problems people have had with GUI vs. playback sync.

b8749fdf21 New codec loader, using the same mechanism as the new plugin loader. API version numbering restarted for the new system. Uses the target ID from configure, so don't change that too often. * Fixed sim_plugin_load_ram() to truncate the tempfile. * Reduced plugin buffer size to 512KB for iriver and iPod.

07c4254135 Don't include the .bss and .ibss sections in the binary image for codecs and plugins. Saves quite some disk space (and buffer space in case of codec changes during playback).

9c0f1a9e39 More stable playback with reduced stuttering when skipping tracks.
Removed CODEC_SET_FILEBUF_LIMIT setting; now playback.c determines how
to buffer the files.

c91e0bbfc9 Cleaned up the messy codec header and library system by merging codec.h, lib/codeclib.[ch] and lib/xxx2wav.[ch] into just codeclib.[ch]. Deleted much of the unused code in the xxx2wav portion. All codecs should now only include codeclib.h, and whatever codec specific headers are needed.

that).
