for testing the effect I took a synch avi(xvid,mp3) file and remuxed it using:
1.
-> Audio starts 10sec before video (this is like I expected)
2.
-> Audio starts 10sec before video (this is like I expected)
3.
-> Audio and video start at the same time (I expected that the video would start before the audio)
4.
-> Audio and video start at the same time (I expected that the video would start before the audio)
=> How to handle negative audio delays with ffmpeg?
Also all of these calls give me:
[avi @ 000001f1b4b8e280] Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
=> How to do it properly to avoid this warning and be save for the future?
Thanks.
