• Two nearly identical ffmpeg commands, one works, the other freezes up

  12 septembre 2019, par dylanjha

  In both of these examples, I’m passing two inputs to ffmpeg applying a filter to the first input, and outputting it all to a .mp4.

  Example 1

  ffmpeg -y -threads 4 -ss 23.536 -t 44.854 -i .tmp/processing/vid-one.webm -ss 13.516 -t 54.874 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-23536-68390.mp4

  Example 2

  ffmpeg -y -threads 4 -ss 68.39 -t 3.646 -i .tmp/processing/vid-one.webm -ss 58.37 -t 13.666 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-68390-72036.mp4

  In the logging output I can get an idea of where it gets hung up.

  Output Example 1

  the output gets to this frame= line and it updates the output like this

• How to include audio in an overlay ffmpeg command ?

  27 avril 2021, par gilad s

  Using ffmpeg I add a video overlay successfully over an origin video (origin has audio, overlay doesn't). However the audio of the origin video doesn't appear in the result video.

  


    ffmpeg  -i source.mp4 -i overlay.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, scale=1280x720[top]; 
  [1:v]setpts=PTS-STARTPTS, scale=1280x720, format=yuva420p, 
  colorchannelmixer=aa=0.2[bottom]; [top][bottom]overlay=shortest=1" 
  -shortest -acodec copy -vcodec libx264 result1.mp4


  


  Even if I execute the following separate command on the result of the previous command - still no audio appears in the new result video.

  


    ffmpeg -i result1.mp4 -i audio.mp3 -c:v copy -c:a aac result2.mp4

  Dialogue: 0,00:00:00.0,00:00:03.0,Default1,,0,0,0,,This box shows the amount of text that fits into one caption. As you change the style of the captions, you can preview how

  And my ffmpeg code is

  ffmpeg -i ./tmp/source.mp4 -t 5 -filter_complex "ass=filename=./tmp/subtitles.ass" ./t mp/output.mp4 -y

  But I didn’t get out expected output.

  The Console is

  Here I’m trying to load font from /home/nodeuser8/tmp/CharmonmanRegular.ttf but ffmpeg load font from /usr/share/fonts/dejavu/DejaVuSans.ttf.

  So how to load fontfile for ass subtitles ?
