    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    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 ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to get the video's duration or number of frames in ffmpeg filter

    1 July 2020, by Reasno

    I'm writing a filter in ffmpeg and I have to get the duration or number of frames in filter_frame function. But the parameters of "filter_frame" function only consist of AVFilterLink and AVFrame:

    


    static int filter_frame(AVFilterLink* link, AVFrame* in) {
    AVFilterContext* avctx = link->dst;
    ExtractContext* privCtx = (ExtractContext*)avctx->priv;
    AVFilterLink* outlink = avctx->outputs[0];
    //here I want to get the duration of total number of frames:
}


    


    I can't find attributes which is related to duration of frame numbers in either class. I have googles but all answers are about getting duration or frame numbers using ffmpeg.exe, which don't meet my requirements because I have to get them in self-written filter in FFMPEG. Thanks for your help!

  • avcodec/mjpegdec: Use correct number of codes for VLC tables

    8 October 2020, by Andreas Rheinhardt
    avcodec/mjpegdec: Use correct number of codes for VLC tables

    Commit 1249698e1b424cff8e77e6a83cfdbc9d11e01aa7 made
    
ff_mjpeg_decode_dht() call build_vlc() with a wrong (too hight)
    
number of codes. The reason it worked is that the lengths of the extraneous
    
entries is initialized to zero and ff_init_vlc_sparse() ignores codes
    
with a length of zero. But using a too high number of codes was
    
nevertheless bad, because a) the assert in build_vlc() could have been
    
triggered (namely if the real amount of codes is 256) and b) the loop in
    
build_vlc() uses initialized data (leading to Valgrind errors [1]).
    
Furthermore, the old code spend CPU cycles in said loop although the
    
result won't be used anyway.
