  • 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 ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • Android mp4 remove rotation and rotate the video stream

    4 mars 2015, par Mathijs Segers

    I’m having some issues trying to remove the rotation value of Android video’s.
    For some reason convertion tools in the cloud cannot seem to handle android’s rotation value correctly. f/e I have a portrait video recorded in 1080x1920 (so the file’s headers tell me it’s actually 1920x1080 with rotation : 90).

    So now I’m trying to convert these video’s to an actual 1080x1920 format when they have this rotation value but i’m kind of stuck, probably using the wrong search terms on SO and Google.

    In the hope of making things clear I’ve actually added some ffmpeg libs to android following these steps, of course with some changes to parameters. I’m building this on a Mac and this all works fine now.
    http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/

    Now the following, I have no real clue how these libs work and how to use them or which I actually need or if I even need them at all.

    Is there anyone who can point me in the right direction of solving my issue ? Basicly the video’s are on my android filesystem and I can access them fully, before uploading I want to check the values and remove and rotate the video’s if needed.

  • ffmpeg : get aspect ratio of input video

    1er janvier 2013, par user732274

    I wrote a shell script which accepts any video file (I mean any kind of dimensions, any sort of rotation, etc.) and it uses ffmpeg to pad that video to 720x576 (resizing it) in order to make it perfectly suitable for a video-dvd without requiring the user to calculate anything. Now : I know I can access the size of the input video by using "iw" and "ih" keywords (in the -vf syntax), but I don't know what's the keyword to access its aspect ratio (of course I don't need to read it in the ffmpeg output : I need to access it in the command line).
