  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?

  • 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':

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

    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

    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 ?

  • Ffmpeg frame extraction with Nvidia GPU acceleration throws "Output file #0 does not contain any stream"

    16 mai 2020, par nickthefreak

    I am trying to use nvidia gpu accelerated decoder api with ffmpeg, to extract all frames from a video file (.MTS) to a folder, but it looks like it's failing for some reason ; I could not find an answer or similar issues.

    I am pretty sure -hwaccel cuvid -c:v mpeg2_cuvid is correct as the file type seems to be MPEG-2 in the file properties, but similar issues happen with the other cuvid decoders as well :

    &#xA;&#xA;

    enter image description here

    &#xA;&#xA;

    I have also tried to run without -c:v flag but then a cuda error is raised and it runs on the cpu :
