How much of a headache would it have been to stretch or shrink the audio in, say, Audacity, so that it would play at the same rate as the video? Was it a constant rate?
- klodolph 6y agoYou’d probably want to do it in FFmpeg, because in order to get the audio in to Audacity and back out again you’d have to use FFmpeg anyway. I also get a massive headache just from using Audacity.
- bronco21016 6y agoI originally tried this for a capture I did that was out of sync and it ended up making matters worse. The issue for me was my video and audio were using separate clock sources on the capture end. This meant the streams started recording at different times AND drifted apart over time. Using a V4L2 capture device I finally managed to get something workable in ffmpeg by using the -ts flag with option 'asb' for both audio and video sources.
