  • FFMpeg mxf streamcopy strips vbi_vanc_smpte_436m stream

    29 décembre 2016, par Vince

    Hi i was using ffmpeg to copy all video/audio/data streams across to another mxf file and noticed that ancillary data streams weren’t being copied and in fact caused an error.

    ffmpeg -i "D:\Media\61003203.mxf" -map 0 -c copy "D:\Media\POC_61003203.mxf"

    I wasn’t looking for the stream to be decoded/encoded but just a stream copy.
    Any ideas ?

  • Revision 9a1ce7be7d : Experimental rd bias based on source vs recon variance. This experiment biases

    Experimental rd bias based on source vs recon variance.

    This experiment biases the rd decision based on the impact
    a mode decision has on the relative spatial complexity of the
    reconstruction vs the source.

    The aim is to better retain a semblance of texture even if it
    is slightly misaligned / wrong, rather than use a simple rd
    measure that tends to favor use of a flat predictor if a perfect
    match can’t be found.

    This improves the appearance of texture and visual quality
    on specific test clips but is hidden under a flag and currently
    off by default pending visual quality testing on a wider Yt set.
