FFMPEG overlay video over image using movie filter resulting video with no sound
22 février 2021, par Herahadi AnI want to overlay srinked video on the top of single image.
I use movie filter to do that. like this


ffmpeg.exe -loop 1 -i Coronavirus00000000.jpg -vf "movie=C\\:/\Users/\Toshiba/\Pictures/\test vcp/\shopi pro.mp4,scale=1180:-1[inner];[in][inner]overlay=70:70:shortest=1[out]" -y out.mp4



It's work. but the problem, the audio from video is removed. The final video out.mp4 has no sound, even though the original video has.


I have read answer on this threat FFMPEG overlaying video with image removes audio


That recommend to Change into
...[padded]overlay=0:0" -y ...
Oradd -map 0:a


But I don't understand how to implement that answer into movie filter

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.
