  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Does MediaCodec truncate incoming packets for decoding ?

    15 octobre 2013, par mathieujofis

    I'm using MediaCodec to decode h264 packets that were encoded with ffmpeg. When I decode with ffmpeg, the frames display fine. However, when I decode with the MediaCodec hardware decoder I sometimes get black bars that show up in the middle of the frame. This only happens if the encoding bitrate is set high enough (say upwards of 4000000) so that any given AVPacket size becomes above 95000 or so. It seems like MediaCodec (or the underlying decoder) is truncating the frames. Unfortunately, I need the quality so the bitrate can't be turned down. I've verified that the frames aren't being truncated elsewhere, and I've tried setting MediaFormat.KEY_MAX_INPUT_SIZE to something higher.

    Has anyone ran into this issue or know of a way I can work around it ?

    I've attached an image of random pixels that I rendered in OpenGL and then decoded on my Galaxy S4.

  • Faster Thumbnail/Image Extraction from Video using FFMPEG ?

    27 août 2012, par mirroredAbstraction

    I am using this command to extract a series of images from a video to express them as a visual time-frame of the video.

    ffmpeg -i inputfile.mp4  -r  1  -t  12  image-%d.jpeg

    Most of my videos are in mp4 format. I am able to extract the images successfully but the time taken for extraction is too long.

    Is there any way I could reduce the time for image extraction ?

    EDIT : It is taking me 60 secs to get 8 thumbnails from a 15 sec long video encoded in MP4 format, I am doing this operation on my Galaxy Nexus(Android Phone) is there any way to improve the speed of operation, ideally I want it be less than  10secs.
