Hi all, I am developing an application that receives a stream of audio samples from a remote server via custom UDP protocol. The stream consists of small sequences of samples, each sequence may have different number of channels (interleaved) and rate. As I understand, the sample_spec of the stream can only be set during the stream's creation (pa_simple_new, pa_stream_new, etc) and there is no way to switch it afterwards. My question is: what would be the most efficient approach to these samples' playback in PulseAudio? I see three options: 1. Keep a single PulseAudio stream, manually resample the sample sequences and mix channels when needed (in order to feed PulseAudio with samples of the same sample_spec) 2. Keep a single PulseAudio stream, close and reopen it with new sample_spec when specs change 3. Keep a number of streams, one for every kind of samples I have to work with Option 1 seems like a lot of manual work, and pretty much resource-consuming, too. Option 2 seems to be terribly inefficient. Option 3 looks like probably the best one, but I am concerned about resource consumption. Is there something I may be missing? Thank you in advance! -- Best regards, Roman
