  • Creating farms of unique websites

    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" (...)

    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...

  • Strange "pause" in video after concatenation of two mp4 videos

    3 octobre 2016, par user606521

    I am concatenating two mp4 videos. The problem is that first video (intro.mp4) lasts 5 seconds, second video (output.mp4) lasts 2 seconds and video created by concatenating them lasts 9 seconds (and should last 5+2 = 7 seconds). In final.mp4 video the last frame from first video (intro.mp4) i shown for additional 2 seconds before second video (output.mp4) is played. It looks like a lag when watching video. What I am doing wrong ?

    list.txt :

    file 'data/intro.mp4'
    
file 'output.mp4'

    command :

    ./bin/ffmpeg -f concat -i list.txt -c copy final.mp4

    output :

  • Faster way of getting number of key frames than "show_frames" in ffprobe ?

    19 novembre 2016, par Will Tower

    I’m making a little in-house utility using ffmpg and ffprobe. Works fine and does what is needed : give a count of the number of key frames in a video file plus some other details.

    Alas, with the large video files this will be used on it can take many seconds for show_frames to return – and I then have to parse the JSON dump of frame data and keep a running count of the total key frames.

    Is there a faster way ? Perhaps it is listed in the "stream" or "format" data dumps and I am not recognizing what it is being called ? I’ve been through the ffmpg and ffprobe docs and didn’t find anything else.

    The problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks
