History
Michael Sevakis 7ad2cad173 Commit work started in FS#12153 to put timing/position information in PCM 
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.

drivers Commit FS#12111 by Stephan Grossklass. Disables output mixer auto gain control on AMSv2. Should fix occasional distortion reported when running the player at very high output levels (e.g. at or above 0dB). 2011-07-24 21:56:24 +00:00

arabjoin.h
ata_idle_notify.c Correct wrong usage of event callbacks all over the place. It's not supposed to return anything, and should take a data parameter. 2009-10-20 21:54:44 +00:00
backlight-sw-fading.c
backlight.c All kernel objects in code shared amongs targets (core, plugins, codecs) 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). 2011-02-14 11:27:45 +00:00
