• Why does ffmpeg output frames starting with 0001 instead of 0000 ? [closed]

  3 février 2020, par AMTQ

  I’m using ffmpeg to extract frames from a video. It all works well but something seems strange : The numbering of the output always starts with 0001 instead of 0000. Below a minimum working example, the output from the console and a picture of the generated frames. I’m using windows shell on Win10.

  ffmpeg -i P1390752.MP4 -vframes 4 frame%%04d.png

  Console output :

  C:\Users\xxxx>ffmpeg -i P1390752.MP4 -vframes 4 frame%04d.png

  What I tried so far :
  1) I restricted the output to 4 frames because otherwise it would take ages. But the problem remains the same when I remove the number of frames and extract the whole video. The problem persists when using a starting point with -ss and a duration.
  2) When I use jpg as output I get some warnings about depreceated pixel format, but the numbering issue remains.

  I can not get rid of the first two warnings concerning the keyframe, maybe this is related ?

• ffmpeg stream segmenting loses some frames after initialization

  You can clearly see that first video is output/2020-02-17-13:39:14.mp4, then something happens and the next video is output/2020-02-17-13:39:18.mp4. After this I lose 3 seconds and my whole videos are delayed by 3 seconds.

  Is my command incorrect or is there something else could cause it ?

• Overlaying a transparent webm on an MP4 freezes at the start sometimes

  23 janvier 2021, par joshlat94

  I'm currently using the command
 ffmpeg -i mainvideo.mp4 -vcodec libvpx -i myoverlay.webm -filter_complex "overlay = 5:5" done.mp4
To overlay a transparent webm on top of my main mp4. But for some reason the output video is frozen for the first 1 second but the audio is completely fine.

  


  I've tried this command with other videos and it works sometimes but most of the time the first few frames seem frozen

  


  Edit.
I have two main mp4 files, broken_source.mp4 and working_source.mp4. Putting the overlay on broken_source results in the output having the first 1 second of video frozen (audio completely fine) but putting the same overlay on working_source.mp4 is perfect and has no issues

  


  Logs for putting the overlay on working_source :
