* Add codecs to librbcodec.Sean Bartell2012-04-25

* More completely flush WMA decoder state on seek to prevent artifact.Michael Giacomelli2012-04-03
| | | | | | | | Each MDCT depends on the previous frame for reconstruction. Previosly these were not zeroed out when seeking, resulting in a few milliseconds of the previous frame playing with the current one. Fix that. Additionally, since the codec treats seeks to the start of a track as a "reset", flush the entire codec state in this event to ensure that everything is reset.

* Don't filter out -O for sims.Thomas Martitz2012-01-22
| | | | | | | | | It's not useful as it means we test code at a different -O level than we run it at. Fixes build errors caused by gcc 4.3. Fix some warnings the change would introduce as well. Change-Id: Id9ff31dc08694b0bfc5272f5e690c41f7918ed22
* Commit work started in FS#12153 to put timing/position information in PCMMichael Sevakis2011-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | 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
