    avcodec: export motion vectors in frame side data on demand · b0352b19
    Clément Bœsch authored
    The reasoning behind this addition is that various third party
    applications are interested in getting some motion information out of a
    video "for free" when it is available.
    It was considered to export other information as well (such as the intra
    information about the block, or the quantization) but the structure
    might have ended up into a half full-generic, half full of codec
    specific cruft. If more information is necessary, it should either be
    added in the "flags" field of the AVMotionVector structure, or in
    another side-data.
    This commit also includes an example exporting them in a CSV stream.
