• FFMPEG result video freezes in the middle of playback

  10 mai 2013, par Revoluzifer

  I'm trying stitch four source videos together into one grid. For testing purposes I'm working with a single source flv using this command :

  ffmpeg -i woohoo.flv -i woohoo.flv -i woohoo.flv -i woohoo.flv \
  
  -filter_complex "[0:0]pad=iw:ih[a];[1:0]scale=w=iw/2:h=ih/2[b];
  
  [2:0]scale=w=iw/2:h=ih/2[c];[3:0]scale=w=iw/2:h=ih/2[d];
  
  [0:0]scale=w=iw/2:h=ih/2[e];[a][b]overlay=w[x];[x][c]overlay=0:h[y];
  
  [y][d]overlay=w:h[z];[z][e]overlay=0:0" -qscale 1 stitched.avi

  The stitching itself is working great, but somehow the resulting video does not show as expected.
  After running for a few frames, it gets stuck at a single frame for most of the video, skipping the frames which should be there.

  While encoding ffmpeg throws a freaking lot of messages like :

  [Parsed_overlay_8 @ 000000000459e080] Buffer queue overflow, dropping.

  Any hints on how to solve my problem ?
  My source flv is h.264 encoded, coming from Red5 media server.

  Edit : Output is :

  root@s15757871:/opt/red5/webapps/woohoo/streams# ffmpeg -i out_3.mp4 -i 3.mp4 -filter_complex "[0:0]pad=iw:ih[a];[1:0]scale=w=iw/2:h=ih/2[b];[a][b]overlay=w:h" -vcodec libx264 -r 30 -acodec copy out_final.mp4

• ffmpeg get machine readable output

  15 mai 2017, par J.S

  I am trying to find a way to get FFmpeg to return a machine readable output. basically, I just want to know if video conversion was successfull.

  I am calling FFmpeg from go code.

  output, err := exec.Command("ffmpeg", "-i", source, "-vcodec", "h264", "-acodec", "aac", "-strict", "-2", destination).CombinedOutput()

  The above code executes this command :

  ffmpeg -i /tmp/pitchVideo-1494844705-102.mp4 -vcodec h264 -acodec aac -strict -2 /tmp/1494844705.mp4

  I get the following output :

• FFMPEG - Concatenate 2 MP4 Files, one has video and audio and the other has only audio

  5 août 2016, par Avi

  I am trying to merge 2 mp4 files using FFMPEG. One of these files has both video and audio (track1.mp4), while the other one has only audio (track2.mp4). The names of these files are listed in a text file called 'filesToMerge.txt' in the following manner :

  file 'track1.mp4'
  
  file 'track2.mp4'

  I then execute the following ffmpeg command to merge them.

  ffmpeg -f concat -i filesToMerge.txt -c copy output.mp4

  However, the concatenated file that is generated consists of only the first file that is listed in filesToMerge.txt. That is, if track1.mp4 (which has both video and audio) is the first file in the list, then only that file makes up output.mp4 (the concatenated file produced) and vice versa.

  I would like for both files to be in output.mp4. I am using Ubuntu 14.04 (if that helps). How can I solve this problem ?

  When I run this command
  ffmpeg -i track1.mp4 -i track2.mp4 output.mp4
  I get the following
