paraslash/alsa_write.c, branch v0.3 paraslash - network audio streaming tools https://git.tue.mpg.de/cgit/paraslash/atom?h=v0.3 2009-11-07T13:06:55Z alsa: Avoid using 0 as a NULL pointer. 2009-11-07T13:06:55Z Andre Noll maan@systemlinux.org 2009-11-07T13:06:55Z urn:sha1:d7f96d2c7c718e3f7d4834fb25b6939a355a0e19 Found by sparse. Alsa timing improvements. 2009-08-29T20:17:55Z Andre Noll maan@systemlinux.org 2009-08-29T20:17:55Z urn:sha1:44b21efca6080fcc88830facd98e50e4c5e66505 This moves the computation of the select timeout from alsa_write_post_select() to alsa_write_pre_select(). The code now computes when the next buffer underrun would occur and uses that value to set the timeout for the next select call. This decreases the number of writes to the alsa handle and therefore also the CPU usage of para_write/para_audiod. Fix memory leaks in [alsa,file,oss]write.c. 2009-07-19T12:16:42Z Andre Noll maan@systemlinux.org 2009-07-19T12:16:42Z urn:sha1:678a55163f159783c688370b9b974a8a5e1fcd06 Small and harmless but anyway. alsa_write: Avoid EAGAIN. 2009-05-31T10:34:39Z Andre Noll maan@systemlinux.org 2009-05-31T10:34:39Z urn:sha1:e7b866a338a22ad07c8e60d405616a8065be89b1 Before writing to the sound device, use snd_pcm_avail_update() to check how many frames alsa will accept and write only that many frames.

Without that change, playback could be delayed by several seconds on some alsa configurations (problem pointed out by Johannes Wörner, thanks). - does not return early on input errors which could cause the last part of the audio stream being skipped. - avoids calling snd_pcm_writei() with a frame count of zero which could happen with the old code in case there's more than zero but less than a full frame of audio data available. - cleans up the documentation of struct private_alsa_write_data Merge branch 'master' into next 2009-05-02T09:50:17Z Andre Noll maan@systemlinux.org 2009-05-02T09:50:17Z urn:sha1:345e7b4adce741621a412c3845712e8540b572ad Use only a single buffer pointer for filters/receivers. 2009-05-02T09:46:46Z Andre Noll maan@systemlinux.org 2009-05-02T09:46:46Z urn:sha1:0855a5fcdbebabacebee968939cf00bf3161cfaf This allows filters to change the output buffer size on the fly.
