• Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  6 juillet 2016, par olega

  Found a lot of helpful answers. But could not find for my problem.
  I am trying to convert .mp4 to .webm. I tried with parameters, without them (like below), but always got same result :

• FFMpeg convert VOB to H264 and multi language

  26 octobre 2016, par gduh

  I try to convert VOB files to H264. I know it seems to be crazy to do that but the goal is to use it with the Apple TV.

  To just converting a VOB file to mp4 with the right audio stream is not really a problem.

  The problem is when the VOB file contains multi-sequences in different languages. For example, in the mp4’s file I will have 3 seconds of video including for example a book on the screen in english, then, the same 3 seconds with the book in french and so on...
  But with the VOB file I will have only the 3 seconds in the right language.

  When I check the VOB file, I only see one stream #0.0 for the video.

  So my question is, how can I avoid to include the differents videos sequences with these different languages ?

  Thx for your help.
