I am just a tiny bit confused about how the loop should work in my audio decoding example I'm trying to make:
I am using ffmpeg to read audio and PortAudio to play. At the moment, the audio sounds completely wrong. And, since PortAudio runs its callback in a different thread, without a call to Pa_Sleep() the application exits immediately. I have pasted code here: http://paste.pocoo.org/show/347705/ This is heavily based on code at http://dranger.com/ffmpeg/tutorial03.html Basically I see it as such: Start PortAudio as normal (Pa_OpenStream, Pa_StartStream) Callback is done in different thread as per standard PortAudio behaviour Fill AVPacket list in my data packet queue structure over and over until audio file is complete While loop should quit on its own when there is no more to decode Pa_StopStream and terminate PortAudio and the application I'm wondering if the call to Pa_Sleep or similar will be necessary to keep the application alive in this case? If so, what values would be safe to use? Some MP3s I have tried have given very odd and untrustworthy duration values.
