Hi! I am implementing a headless media player. I have played a bit with the pulseaudio client asynchronous API and I am able to play my files with no problem, which is great. However, I have some questions about pulse audio usage: - is it OK to open a stream as soon as the application starts, even if no sound will be eventually played? Or should I open a stream only when a song is requested to be played and close it once it has finished?
Can you enforce the same audio format throughout the application lifetime? It seems saner to keep the PA mainloop and the PA context for the whole application, but create a new stream only when you start playback. You can do either way though.
- is it OK to use a single stream for several songs or is it better to use separate streams, one for each song?
You can of course do that. If you implement cross-fading, it's even hard to avoid. Remember to update the stream meta-data though.
I thought it may be easier to use a single stream to implement gapless playback, but I may be wrong.
Yes. -- Rémi Denis-Courmont _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
