  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • FFMPEG : Need to mix dow multiple audio stream to single stereo

    17 avril 2018, par Serge Dumoulin

    I have an input file with 2 stereo stream of audio.
    I am trying to create an output wav file with the audio mixdown :
    first stereo stream mixdown to left channel of a single stereo stream
    Second stereo stream mixdown to right channel of the same stereo stream.
    So output file have only one stereo stream.
    I have tried different things but its not clear how to manage streams and channels inside them. Found no example on how to do this.

    I’ve tried playing with -filter_complex , amix, and amerge filters, as well as the -map parameter, but I can’t seem to find the right combination of values.

    Here was my input file looks like :

    I’m trying to combine some .ts files using ffmpeg. They’re encrypted, but I have the key in the dir with the other files. I used the info from this page to try to combine these files. This is the full code :

playlist.m3u8: Invalid data found when processing input

    It seems someone else on the question I linked to above had the same error that I’m having but nobody responded to it. Any idea what’s wrong ? Thanks

    EDIT : After looking over some more info, the key is also encrypted. This is the key : AI+UjSUn1lhJ/JHbEf5NyVjRBgqScYEKgx18h85zi5E=

    User kape123 managed to get a plain 16 byte key, but there haven’t been updates on the question linked above since September of 2017. The error with the m3u8 file still persists on my end. Thoughts ?
