f1b0f67553 Build an appropriate channel map for PulseAudio 2013-02-08 18:59:48 -08:00

209d09ae13 Avoid locking PulseAudio's mainloop when starting and stopping capture 
The mainloop is already locked by the caller, and double-locking interferes
with the subsequent wait.

0865db564f Move the device lock into the backend function table 
For backend-specific implementations: this should hold the audio mixer loop for
playback devices, and provide recursive mutex behavior.

ac4fc4026c Add a device method to retrieve the active latency 
This is effectively the time until the next update will be heard by the user,
or the closest approximation thereof, in nanoseconds.

f42f655ea9 Don't unlock the pulseaudio mainloop when mixing 
Lock contention could cause a lengthy delay between mixing and writing the
audio. There shouldn't be any risk of dead-locking as the device lock should
never be held when the mainloop gets locked.

90ca6675c2 Allow PulseAudio to spawn a server by default 
Since only one backend is used at a time now, the issues with device ownership
aren't really prevelant anymore. An application that tries to open all
enumerated devices won't run into the problem of spawning a server and end up
preventing other backend devices from working.

0db9730a50 Add an option to allow PulseAudio to move streams 
This could be made the default, if there's a safe way to update the AL device
specifier.

3131104595 Filter out a couple pulseaudio stream properties by setting them to 0-length data 
It seems Qt/Phonon will globally set media.role and phonon.streamid properties,
causing them to apply even to our streams if they happen to be loaded in the
same process. This is particularly a problem because media.role gets set to
"event", preventing the streams from showing in pavucontrol.

fe6e532c87 Use a separate backend callback to start playback of the device 
This allows us to properly update the ALCdevice and its resources with the new
parameters before starting playback, instead of expecting the mixer to block
and wait after it has begun.

This also lets us avoid holding the device lock while resetting and starting
the device, which helps prevent lock inversion on some backends (ie, one thread
locking A then B, and another thread locking B then A), ultimately allowing
certain backends to asynchronously update the ALCdevice without risk of lockup.
Capture still has issues here, however.

346f1ac293 Don't allow the PulseAudio stream to move 
Since the device specifier isn't updated to reflect the change, it's best to
not allow it to move. This should be fixed eventually.
