  • Video encoding with AV1 - FFmpeg

    5 juin 2020, par ringola27

    I was trying to encode a raw video with AV1.

    



    I used : ffmpeg -i netflixboxing720p.y4m -c:v libaom-av1 -b:v 500k -strict experimental netflix720p500AV1.mp4

    



    I took 2 hours and when I open the created video I get nothing. I would play the Video.
Do I need an other command line ?

  • FFmpeg auto rotate video when copying video stream without re-encoding

    25 février 2019, par Mahfujur Rahman

    I have been trying to convert an mp4 (portrait) file to mkv. As the mkv container support any video and audio stream, I am copying the audio and video stream to the output container. The command I’m using

    ffmpeg -y -i test.mp4 -vcodec copy -acodec copy test.mkv

    File info for test.mp4 is following

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4':
    
  Metadata:
    
    major_brand     : mp42

      creation_time   : 2019-02-23T11:18:50.000000Z
    
      handler_name    : SoundHandle

    Now, the problem is that the output video I get from ffmpeg is a 90 degree counter clockwise rotated video. The reason I believe is the following info being removed from output file,

    Side data:
    displaymatrix: rotation of -90.00 degrees

    File info for rotated output file test.mkv

    Input #0, matroska,webm, from 'test.mkv':

      DURATION        : 00:00:25.813000000

    But when I convert this rotated output test.mkv to mp4 again, I get the portrait file. The displaymatrix side data appears again in the file info.

    Converting the same mp4 file to m4v by copying the steam works fine.

    So, this whole thing is very much confusing to me.

    Now my question is, how can I convert the mp4 file to mkv without re-encoding and avoid getting rotated output ?

    In this post they solved it for c++. I am working on android and using ffmpeg android wrapper to use the ffmpeg library. Is there any ffmpeg flag to handle this situation ?
