• ffmpeg how to concat and join two video clips


    This normally works but if not use my mencoder solution if the output video does not play past the joined time. the contents of list.txt need to look like this: file somefile.mp4 file somefile2.mp4 then run ffmpeg ffmpeg -f concat -i list.txt -c copy CME-2-router-dial-peer-final.mp4 The result is almost instant joining since there is no video processing since we are........
  • mencoder instead of ffmpeg to join or concatenate video files with different audio streams


    The problem for me is that Ihad two videos with different types of audio streams. ffmpeg would join them but they would not play past the point of the join. So Iused mencoder like below and it joined the audio and made them both mp3 streams and it worked! -oac mp3lame specifies the audio to be convered into an mp3 stream using the lame codec. after the oac the two files are the ones to be joined. the -o is the name of the outp........
  • ffmpeg how to watermark and concatenate in one command


    If you were in my boat you were frustrated that you had to double encode, eg. one separate encode for watermark and a separate from concat and it's not easy to figure out this with ffmpeg on your own. However it is a nice way to save time! ffmpeg -i file1.mp4 -i file2.mp4 -i file3.mp4 -i watermark.png -filter_complex "[0:v]setpts=PTS-STARTPTS[v0]; [1:v]setpts=PTS-STARTPTS[v1]; [2:v]setpts=PTS-STARTPTS[v2]; [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[v][aout]; [v][3:........
  • ffmpeg trouble concatenating similar but different files


    When things go wrong your video is basically unplayable or the first video plays fine and then freezes when moving on to the next. Generally if both videos weren't produced with the exact 100% same settings you will have issues. You can try the basic concat but it often won't work right. Solution for me: My example uses 3 videos in total so "n=3" and a=1 to include audio. ffmpeg -threads 12 -i file1.mp4 -........
