  • 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.

  • ffmpeg encode image sequence

    1er juillet 2013, par user706167

    ffmpeg.exe -f image2 -i image_%05d.png -vcodec mpeg4 -b 800k video.mpg

    It doesn't work :

  • Use promise.pipe for jQuery version before v1.8.

    15 mai 2020, par blueimp
    Use promise.pipe for jQuery version before v1.8.

    jQuery versions before 1.8 require promise.pipe if the return value is used, as promise.then in older versions has a different behavior, see :

  • ffmpeg merge multiple (N) mono audio channels of a MXF video to multiple (M) stereo channels of MP4 video

    14 février 2020, par Laura

    I have an MXF file with 16 audio mono streams and I need to recode it in a mp4 file with 2<=n<=16 channels merging input streams, e.g. input channels 1 and 2 on output channel 1 and 9 and 10 on output channel 2. This job will be done with ffmpeg. I read the documentation and found the amerge and amix filters that would be nice, but they output one channel only. Is there any solution for this problem ?

    Thanks,
    Laura
