2011-12-17Commit to certain names for cache coherency APIs and discard the aliases.Michael Sevakis
Wouldn't surprise me a bit to get some non-green. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31339 a1c6a512-1295-4272-9138-f99709370657
2011-09-01Remove obsolete init cruft from audio system because of diminished ↵Michael Sevakis
dependencies. All talk/voice dependency in playback.c should be imminently removable. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30401 a1c6a512-1295-4272-9138-f99709370657
2011-08-30Submit parts of FS#12189 regarding codec API. Replaces access to global ↵Andree Buschmann
settings with a dedicated function to determine if the current track shall be looped. Used by several synthesizer codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30391 a1c6a512-1295-4272-9138-f99709370657
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
2011-07-21is_codec_thread() is not needed anymore since PCM buffer calls other than ↵Michael Sevakis
volume level are no longer made by the voice thread. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30189 a1c6a512-1295-4272-9138-f99709370657

2011-05-08Move implementation of codec_get_buffer() to codec.c, make related variables ↵Andree Buschmann
static. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29839 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
2011-03-16Purge buffer and codec APIs existing exclusively in support of mpa.codec and ↵Michael Sevakis
fix that to not require them: buf_get_offset and ci.advance_buffer_loc. Sort APIs; everything must become incompatible. :( git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29595 a1c6a512-1295-4272-9138-f99709370657
2011-03-06Remove malloc_buf references from playback.c since it's no longer used for ↵Michael Sevakis
anything and align the codec slack space buffer that is now use as the malloc buffer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29533 a1c6a512-1295-4272-9138-f99709370657
2011-03-05Change the thread api a bit.Thomas Martitz
* Remove THREAD_ID_CURRENT macro in favor of a thread_self() function, this allows thread functions to be simpler. * thread_self_entry() shortcut for kernel.c. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29521 a1c6a512-1295-4272-9138-f99709370657
2011-02-23Give playback engine better control over the codec. Codec simply follows ↵Michael Sevakis
commands and doesn't concern itself with audio state. 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. This is still at an intermediate stage but works. Codecs and plugins become incompatible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29387 a1c6a512-1295-4272-9138-f99709370657
2011-02-14All kernel objects in code shared amongs targets (core, plugins, codecs) ↵Michael Sevakis
should be declared SHAREDBSS_ATTR as any core could potentially touch them even though they seem only to involve threads on one core. The exception is target code for particular CPUs where proper allocation is fixed. playlist.c was a little odd too-- use one mutex for the current playlist and a separate one for created playlists (still pondering the necessity of more than one). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29305 a1c6a512-1295-4272-9138-f99709370657
2011-02-03Submit FS#11918: Add 2 more codec types to be able to differentiate between ↵Andree Buschmann
AAC / AAC-HE and MPC SV7 / SV8. Additionally handle ATARI soundfiles in get_codec_base_type() as intended. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29199 a1c6a512-1295-4272-9138-f99709370657
