  • 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 cache whole video stream and save

    19 juillet 2016, par Luiz

    I have a security DVR that can stream a video recording using the RTSP protocol. I can record the playback using ffmpeg and save it to a file, but for a 20 min video, I have to watch the video to save or wait the whole playback time.
    I’m using :

    ffmpeg -i "rtsp://mystream" -r 15 -acodec copy -vcodec copy myvideo.mp4

    to do this

    Is there any way to buffer the whole stream and just save it to a file using ffmpeg, without the need to watch or wait the whole 20 minutes playback ? I don’t need to reencode anything since the stream video format is good enough for me.

    Thanks in advance

  • FFMPEG command not working on MP4 files as expected

    21 février 2020, par DavidB

    I am trying to set the output time offset for mp4 file.

    ffmpeg -ss 13.554000 -i input.mp4 -c copy -t 10 -output_ts_offset 13.554000 output.mp4

    This code works for WEBM file as expected but not for MP4.
    In webm it delays start time of video to the specified timestamp and duration is 23.554 but in mp4 it just cuts the video, start time is set to 0 and duration is 10
    Cannot find what is problem.

    ffmpeg -ss 12.960000 -i v.mp4 -c copy -t 10  -output_ts_offset 12.960000 output.mp4
