• ffmpeg change the fps value of the MKV container

  29 juin 2017, par Marios Staikopoulos

  I’ve been using the SVP video plugin, and we have come across an issue where an incorrect container fps value is causing audio desync.

  It seems a set of videos that are actually encoded at 23.976 fps are showing as 23.81.

  How can I remux the file using ffmpeg to make it show 23.976, since the file doesn’t actually need re-encoding ?

  I have tried the -r and -framerate options to no avail.

  What the file shows with ffprobe, 23.81 fps, when it is actually 23.976 fps
