• ffmpeg "Error reinitializing filters !" on some webm videos

  9 février 2023, par The Blind Hawk

  I have a dozen of webm videos I need to resize with the following :

  


  ffmpeg -i input.webm -vf “scale=w=360:h=270:force_original_aspect_ratio=2,fps=10,crop=360:270” output.webm


  


  I tried the command and it worked fine for some webm videos, but most of the returned the following error :

  


  [AVFilterGraph @ 0x7fcb3db076c0] No such filter: '“scale'
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
[libopus @ 0x7fcb3c10a000] 1 frames left in the queue on closing
Conversion failed!


  


  I checked that ffmpeg still worked fine with previously successful files.
  
How can I get ffmpeg to work with the remaining wemb videos ?

  


• FFmpeg stdin "output file is empty, nothing was encoded"

  2 février 2023, par brock

  Just trying to stdin and stdout a simple CAF to MP3 conversion. Output looks exactly the same except using stdin does not encode anything. Windows 10. I'm going bananas here. Please advise.

  


  Using - (stdin)...

  EDIT : Command syntax is ok. Works as expected with a WAV file. I upgraded FFmpeg now I get errors using stdin. So it is the file that is to blame. However, I do find it odd that using -i is fine, but stdin is not.

• How do I resolve ffmpeg concat command error "unknown keyword..." ?

  6 décembre 2023, par Scorb

  I am trying to concatenate two video files using ffmpeg, and I am receiving an error.

  


  To eliminate compatibility issues between the two videos, I have been concatenating the same video with itself, and the same error persists.

  


  ffmpeg \
  -f concat \
  -safe 0 \
  -i intro_prepped.avi intro_prepped.avi \
  -c copy \
  concat.avi  


  


  And the error output I receive is....

  


  


  [concat @ 0x220d420] Line 1 : unknown keyword 'RIFFf� ?'
intro_prepped.avi : Invalid data found when processing input

  


  


  I have tried various combinations of concat flags and have not been able to get it to work. Has anyone seen this error before ?
