  • 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" (...)

  • av_seek_frame() Can't seek to the place I want

    5 juillet 2022, par alexander chen

    I want to intercept a frame of my video file, so I used the av_seek_frame function, the timestamp value I tried using timestamp*AV_TIME_BASE and timestamp/(av_q2d(videostream->time_base)*av_TIME_BASE), but no matter what I use Which one, the obtained frame is always not what I want, and it is observed that the frame time that I want is very different (so the accuracy problem of AVSEEK_FLAG_BACKWARD is excluded here).
My code is as follows :

    



    double tmp0 = timeStamp/(av_q2d(inputVideoStream->time_base)*AV_TIME_BASE);
//    double tmp0 = timeStamp * AV_TIME_BASE;
code = av_seek_frame(inputAVFormatContext, videoStreamIndex, tmp0, AVSEEK_FLAG_BACKWARD);

    vaapi_h265 : Fix slice header writing
    

    This was not observed earlier because the only syntax element which
    it normally misses with the current setup is slice_qp_delta, but that
    is always going to be zero (in IDR frames QP isn’t varied on the
    slice) which will always exp-golomb code as a single 1 bit. The
    immediately following part is the byte alignment, which is always a 1
    bit followed by 0s which are ignored, so as long as the bitstream is
    never aligned at that point we will never notice because the only
    difference is that an ignored bit is a 1 instead of a 0.

    checkasm : lls : Use relative tolerances rather than absolute ones
    

    Depending on the magnitude of the output values, the potential
    errors can be larger.

    This fixes errors in the lls tests on x86_32 for some seeds,
    observed with GCC 11 (on Ubuntu 22.04, with the distro compiler,
    with -m32).
