Hi all,
I am running into some troubles with my linux plugin for the vdr. I want to play audio in sync of video. My current solution is to buffer about 500ms of video on the output device (pts based FIFO). I can play audio with alsa, but sometimes I am not in sync with the video. So I want to set start threshold to 0 to disable automatic playback start. Instead I want to buffer audio and start playback manual, if pts of video is near current scr clock of output device. What are my options to manually start playback?
thanks, -- Christian Gmeiner, MSc
