  • ffmpeg concat two videos with different sizes encounter "do not match" error

    1er juillet 2019, par baojieqh

    I’m trying to concat 4 mp4 files. I’m using the command below but not able to concat

    ffmpeg -i L00.mp4 -i L01.mp4 \
    
  -filter_complex "[0:v] [0:a] [1:v] [1:a] concat=n=2:v=1:a=1 [v] [a]" \
    
  -map "[v]" -map "[a]" output.mp4

    Getting this error :

    Input link in1:v0 parameters (size 1150x722, SAR 1:1) do not match the corresponding output link in0:v0 parameters (1158x690, SAR 1:1)

    This command from this post

    ffmpeg -i L00.mp4 -i L01.mp4 -filter_complex \
    
"[0:v]scale=1158:722:force_original_aspect_ratio=decrease,pad=1158:722:(ow-iw)/2:(oh-ih)/2[v0]; \
    
 [1:v]scale=1158:722:force_original_aspect_ratio=decrease,pad=1158:722:(ow-iw)/2:(oh-ih)/2[v1]; \
    
 [v0][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" \
    
-map "[v]" -map "[a]" -c:v libx264 -c:a aac -movflags +faststart output.mp4

    getting this error :

    Filter pad has an unconnected output

    the dimensions of L00.mp4 is 1158 × 690, L01.mp4 is 1150 × 722.

    how to fix this ?

  • Output video file of ffmpeg command video and audio doesn't match

    6 juillet 2022, par Barry

    i'm trying to trim a video file using ffmpeg using this command&#xA;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.
