  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • cpp code to use ffmpeg static library, compress and convert from one format to another [on hold]

    3 juillet 2017, par Herdesh Verma

    I am new to ffmpeg library and don’t know much about ffmpeg library. I need to write a cpp code that could use static ffmpeg library and do compression along with conversion of format. Till now i managed to get below program working which can convert .mov file to .mpeg format and compress 125MB file to 18MB.

  • FFMPEG Unable to Decode Quicktime QDMC Stream (No decoder for stream)

    23 août 2017, par mbmast

    We are using FFMPEG to convert iPhone video to MP4. This requires an AAC decoder which is not included in any binary distributions of FFMPEG (due to licensing issues). The solution is to download the FFMPEG source and compile it yourself. I’ve done this, apparently incorrectly, as I cannot decode the audio stream. I am getting this error :

    I suspect that I failed to compile and include the correct codec library when I built FFMPEG. The problem is I don’t know which library I should have built/included. I haven’t found anything that says to decode QDMC audio in FFMPEG you need the XXXXX library.

    Here’s the complete list of decoders that my build supports :
