Hi,
I'm sharing a little progress with refactoring the audioOutput code:
I'm preparing the code for an API with an opaque audio_output struct,
to minimize ABI dependencies to the MPD core. I have already created
a patch which moves each output plugin into its own thread, but this
one needs a little more work and testing.
I have imported 9 patches from Eric's branch, most of which deal with
optimizing ALSA output. For those with high ALSA CPU usage: try to
boot Linux with hpet=force, and set "hpet" as clock source.
Max
Eric Wong (9):
alsa: optimistically try resuming from suspend
alsa: capitalize "ALSA" consistently in messages
alsa: get rid of the needless canPause flag
alsa: avoid unnecessary heap usage if we don't set a device name
alsa: move bitformat reading code out of the way
alsa: only run snd_config_update_free_global once atexit
alsa: snd_pcm_sw_params_set_xfer_align is deprecated
alsa: use blocking instead of non-blocking write
storedPlaylist: correctly expand path when writing
Max Kellermann (7):
timer: constant pointers
output: removed keepAudioOutputAlive() declaration
output: renamed method names
output: moved code from audioOutput.c to output_control.c
output: renamed the functions in output_control.c
audio: replaced copyAudioFormat() with simple assignment
audio: moved cmpAudioFormat() to audio_format.h
