2006-05-05Hopefully fix some old audio playing during manual track skip w/o crossfade. ↵Brandon Low
Worst case was 1/5 second of audio from pcmbuflen bytes later than the playign position of the old track would play. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9876 a1c6a512-1295-4272-9138-f99709370657

2006-04-13Ensure that the buffer doesn't get out of sync on rebuffer track changes. ↵Brandon Low
Remove the concept of pcmuf_boost_mode as it doesn't seem necessary, and adds an unnecessary way for the CPU to stay boosted. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9646 a1c6a512-1295-4272-9138-f99709370657

2006-04-05More work on swcodec. No significant pcmbuf functions are called from the ↵Brandon Low
audio thread now. Do not be surprised if seek or skip behavior gets weird after this, but it Works for Me (TM), and is a significant step in the right direction. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9510 a1c6a512-1295-4272-9138-f99709370657

enough space for the next whole audio chunk now, so it's faster too git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8678 a1c6a512-1295-4272-9138-f99709370657

2006-02-07Rework PCM bufferBrandon Low
* Linked list instead of static array buffer pointers * Variable sized chunks * Improved mix handling * Reduction in duplicated code * Reduced IRAM usage w/o sacrificing performance * Converted to almost entirely unsigned math * Add pause function to reduce pcm_* exposure to playback. This WILL break playback on the iPod until linuxstb makes a followup commit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8612 a1c6a512-1295-4272-9138-f99709370657
