• FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"

  26 janvier 2020, par Ham789

  I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.

  First I create the .Y4M video :

  ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4M

  Then I try to input it to ffmpeg :

  ffmpeg -i temp_raw_video.Y4M 

  However I get the following error in the terminal : temp_raw_video.Y4M: Operation not permitted

  I have checked the permissions for the ’temp_raw_video.Y4M’ file and I have both read and write permissions.

  I have tried the above with .MOV videos from an iPhone and it works fine.

  The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.

  What is going on here ? Please see the GH012088.MP4 file info below :

  I tried different FFmpeg versions but no luck
  
I'm out of ideas, how can i continue debugging ?
