    rtpenc: Allow packetizing H263 according to the old RFC 2190 · c4584f3c
    Martin Storsjö authored
    According to newer RFCs, this packetization scheme should only
    be used for interfacing with legacy systems.
    Implementing this packetization mode properly requires parsing
    the full H263 bitstream to find macroblock boundaries (and knowing
    their macroblock and gob numbers and motion vector predictors).
    This implementation tries to look for GOB headers (which
    can be inserted by using -ps <small number>), but if the GOBs
    aren't small enough to fit into the MTU, the packetizer blindly
    splits packets at any offset and claims it to be a GOB boundary
    (by using Mode A from the RFC). While not correct, this seems
    to work with some receivers.
