  • 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 (...)

  • How to create an H264 video for specific Libav decoding

    16 octobre 2013, par James491

    I'm creating a program that decodes and displays videos using Libav. I have complete control over the videos the program uses because I make them beforehand. I am able to seek and decode the videos as needed but only after adjusting to a few quirks of x264 encoded videos. For instance, I have to add 8-10 extra frames at the end of my videos to be able to decode and seek to the original last frame. Is it possible to further customize the encoding of an H264 video using ffmpeg or another application, or perhaps some parameters I can initialize in AVFormatContext or AVCodecContext, in order to solve something like decoding the last frames ? Also, are there any specifics I can add to the video file or implement in decoding to decrease seek time, since all seek commands and positions are predetermined ? My current seeking function is just composed of an avformat_seek_file(...) followed by avcodec_flush_buffers(...). I am already seeking to key frames. I am willing to read and learn if all you have is a recommended page or article to investigate.

  • Pack H264 frames into MPEG2-TS

    13 décembre 2016, par Diz

    I have a live stream distributing raw H264 frames. The frames are encoded with x264. I am able to play the stream with ffplay, so it is working fine. Now I’d like to retransmit (or at least save locally in a MPEG2-TS file) this stream in a MPEG2-TS format using C/C++ code.

    What is the best way to achieve that ? I tried to investigate FFMPEG library and it looks like a complete hell for me. I also tried the code from this answer. I am able to write AVI file with that code, but if I replace "avi" with "mpeg" in the source code, the resulting video file cannot be played with a video player (VLC, mplayer) saying "MPEG : FATAL : EOF while searching for sequence header.".

    Question : What library or a sample code can you suggest me for this task ? Thanks in advance.

    Using LUbuntu 16.04.
