  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • ffmpeg smooth video upscaling

    21 janvier 2013, par bbbonthemoon

    I've got some old videos in 320x240 that I want to upscale to 640x480

    DISCLAIMER : I know upscaling always ruins quality.

    My problem is that, "regular" upscaling options in ffmpeg(-s or scale filter) always give much worse results comparing to manual resizing in any media player when watching video(Resize 2:1 option in Ubuntu's Movie Player for example). So, it's clear that there are better algorithms, which are used by the player to upscale the video. I just dont know how ta make ffmpeg use them, I'm newbie video converter :-) I need your help with converting options for ffmpeg for smooth as possible upscale.
    Thanks in advance !

    I also tried ffplay and here is the output
    enter image description here

    The only software i came across that can open this video is from Matrox and it doesn’t allow exporting to other formats
    enter image description here
    I appreciate if some one can direct me to codecs that can handle this videos. I would like convert to other video formats for further processing.

    Edit :
    I have attached sample video here

    I also tried the latest ffmpeg

  • Ffmpeg : Output a video made of several video chunks of the input video

    20 mai 2013, par mad

    I was wondering if it was possible to output a video made of several extracts of the input video.
    For example outputting a video made of the first 10s of each minute of the input.

    I know you can do it programmatically, calling several time ffmpeg with -ss and -t to make the chunks and then merge them, but is it possible to do it in one command using video filters ?

    Thanks !
