2011-08-28Remove obsolete 'ci->set_elapsed()' from mpc.Andree Buschmann

2011-08-28Commit work started in FS#12153 to put timing/position information in PCMMichael Sevakis
buffer chunks. * Samples and position indication is closely associated with audio data instead of compensating by a latency constant. Alleviates problems with using the elapsed as a track indicator where it could be off by several steps. * Timing is accurate throughout track even if resampling for pitch shift, whereas before it updated during transition latency at the normal 1:1 rate. * Simpler PCM buffer with a constant chunk size, no linked lists. In converting crossfade, a minor change was made to not change the WPS until the fade-in of the incoming track, whereas before it would change upon the start of the fade-out of the outgoing track possibly having the WPS change with far too much lead time. Codec changes are to set elapsed times *before* writing next PCM frame because time and position data last set are saved in the next committed PCM chunk. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30366 a1c6a512-1295-4272-9138-f99709370657

2011-04-27Commit FS#12069 - Playback rework - first stages. Gives as thorough as ↵Michael Sevakis
possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once. 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
2011-02-20Enforce that codecs wait for their metadata in a proper-ish and consistent ↵Michael Sevakis
manner. Sort of a halfway patch; best would be to give them an internal copy of the current track information which lasts unaltered by playback until a track switch or unload. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29348 a1c6a512-1295-4272-9138-f99709370657

2010-03-14Fix FS#11103. Resuming musepack files was handled wrong since ages. This ↵Andree Buschmann
change converts the decoders exact sample position to an estimated byte position within the file. The resume position in samples is calculated the reverse way, git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25164 a1c6a512-1295-4272-9138-f99709370657
2010-03-07Major change to musepack decoder: Import v1.3.0 (r458 from svn.musepack.net) ↵Andree Buschmann
to rockbox. Several adaptions in the musepack decoder were made to get the library work and perform fast under rockbox on several targets. With this change mpc sv8 is supported, including seek, replay gain and metadata support. The decoding speed is a 1-4% lower than the last implementation. Reason for this is main restructuring in the bitstream demuxer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25056 a1c6a512-1295-4272-9138-f99709370657

This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements. It may also belong in buffering not playback, haven't decided for sure git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15475 a1c6a512-1295-4272-9138-f99709370657

2007-02-10SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback ↵Michael Sevakis

2007-02-07Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657
2006-11-26FS#6357, patch 1: let iramcopy and bss share the same space in codecs andTomasz Malesinski
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11606 a1c6a512-1295-4272-9138-f99709370657
