Output video file of ffmpeg command video and audio doesn't match
6 juillet 2022, par Barryi'm trying to trim a video file using ffmpeg using this command

ffmpeg -i input.mp4 -ss 00:05:20 -t 00:10:00 -c:v copy -c:a copy output.mp4
. The problem is when i open the output video, the audio starts normally but the video appears only 5 seconds after. I tried removing the-c copy
option and output is accurate but the process is very slow. So my question is how to make output video/audio match when using-c copy
option, or how to make the process faster when not using-c copy
option. It's my first time using this so i don't know much about video/audio encoding, i am just trying to extract a video clip from a php script.
