Streaming audio and video - Raspberry Pi Forums
i trying capture video camera board , combine audio usb sound card. problem audio lags on 2 seconds , video on 2 seconds behind that!
using ffmpeg below. there still major sync issues if write data file instead of streaming it.
can't attach log ".txt" , ".log" extensions not allowed. here is:

test audio , video separately see latencies then.
don't receiving software - many pc based systems deliberately have large input buffers cope network variability.
suspect a/v sync issues due raspivid being spun , producing frames before audio side starts @ all. have provided fixed frame rate of 25fps both apps, there backlog of few frames stuck in output fifo never consumed. don't ask me how around using raspivid , piping output around. might better off using v4l2 driver , getting ffmpeg talking that.
