I've spent an hour trying to record audio and sync'ing with the video. I'm gonna paste my findings here and possibly get back to this issue when I have the time.
Just put -f pulse -ac 2 -i default to ffmpeg command and it'll record the audio. However, ffmpeg is very picky about ordering of the args. You must put these options after output path.
Hi, I've been troubleshooting a bit and apparently ffplay is unable to work with multiple streams.
If you want to give multiple inputs to ffmpeg, the -i input_url should be the argument in the 'group' for that input. So -f pulse -i default should either be the first argument "group", or be placed after the -i -.
What is is specifically that you want to achieve and what is not working yet?

is very picky about ordering of the args. You must put these options after output path.Also, I've tried to use the arg
-use_wallclock_as_timestamps 1
, but it wasn't good enough. This thread has a few other methods to try: https://superuser.com/questions/1042988/ffmpeg-audio-out-of-sync-when-transcoding-demuxing-from-dv/1054478I've also tried to replace
ffmpeg
withgst-launch
, but I only managed to capture the first frame and that's another story anyway.The text was updated successfully, but these errors were encountered:
