    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.

  • How to detect a common scene in a set of videos with ffmpeg

    6 août 2019, par Hans J

    I have a set of videos that are assumed to contain a common (or very similar) scene. I want to be able to detect (with FFmpeg) what that common scene is, how long the scene is, and where the scene is in each individual video.

    The scene would be assumed to be longer than 10 seconds (This is an arbitrary choice, it can be changed).

    The final output of the command would include the various time-codes of the instance of the scene in each video. Assuming a timebase 1/1, with a common scene that is 60 seconds long, an output would along the lines of :

    Video1.mp4 0 60
    
Video2.mp4 120 180
    
Video3.mp4 50 110
    
Video4.mp4 null

    where video4 does not contain any common scene.

    For example, I could have three episodes of a TV show. They all contain the same commercial. Without knowing what that commercial is, I want to be able to find where that commercial shows up in each of the episodes.

    Note : For the purpose of a good solution, the common scenes do not have to exactly match. Because there could be artifacts or embedded subtitles in one episode and not the other.

  • avcodec/ffv1dec_template : Optimize common case in run mode

    avcodec/ffv1dec_template : Optimize common case in run mode

    Fixes : Timeout (14sec -> 9sec)
    
Fixes : 13398/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_FFV1_fuzzer-5664106709778432
    

    decode_line() becomes 1% faster for fate/vsynth2-ffv1.avi
    
for another fate sample there is a 0.5% speedup
    
the effect should be bigger for files with "flat" colored areas
    
the new faster branch is used in 97-100% of the cases in fate samples
    
compared to the older more complex (which i tested)
    

    vsynth3-ffv1-v3-bgr0.avi had the lowest percentual useage of about 97%
