  • 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 ;

  • Untiy VideoPlayer error - The byte stream type of the given URL is unsupported

    24 avril 2018, par Nika Kasradze

    I’m on Unity 2018.1.0b13 trying to play a video from a local server.
    I’ve transcoded the video myself with ffmpeg. This is the encoding of the streams (by running ffmpeg -i v1.mp4) :

    Stream #0:0(eng) : Video : h264 (Constrained Baseline) (avc1 / 0x31637661), yu v420p, 960x540, 1244 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default)

    Stream #0:1(eng) : Audio : aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 317 kb/s (default)

    In the folder of my v1.mp4 file I’m running http-server so that the file is available at http://127.0.0.1:8080/v1.mp4

    In unity I’m trying to play the video via this URL but I keep getting this same error, no matter what codec I try for encoding :

    WindowsVideoMedia error 0xc00d36c4 while reading http://127.0.0.1:8080/v1.mp4

    Context : MFCreateSourceReaderFromURL

    Error details : The byte stream type of the given URL is unsupported.

    Track types :

    The same video plays ok on Android so I’m guessing it’s just Media Foundation that’s messing me up, not Unity. Any suggestions on how can I make this work in Unity ?

    Thanks !

  • Suppress black margins on the sides of an animation

    26 avril 2018, par Clinton Winant

    I need to make an animation out of a collection of jpeg images. The image size, as given by display, is 1200x900. I can control the size of the jpg images with convert, but not sure what a good size would be. I use the following ffmpeg call :

    ffmpeg -f image2 -i img%04d.jpg -r 24  sound.avi

    In spite of a long string of warnings like

    Past duration 0.879997 too large

    sound.avi is produced, however the animation includes black right and left margins (see attached screen shot of the first frame)

    totem - frame 1

    that I need to suppress. I am under the impression that the 4x3 format of the jpg images is standard ? I view the animation with

    mplayer sound.avi

    The OS is Debian buster

    Further experiments suggest that the black margins disappear if the jpg files have an aspect ratio 16:9. Is that the only AR possible ?

    The output of

    ffmpeg -f image2 -i img%04d.jpg -vf cropdetect -vframes 5 -f null
