Description Tim-Philipp Müller 2012-07-24 13:01:22 UTC 
Applies to both 0.10 and 0.11, though it seems to complain much more in 0.11.

Not sure if it's a demuxer/decoder/parser issue or a problem with the stream or ..

    avdec: require alignment=au for h264
    
    Because we don't use a parser anymore we need to make sure that we feed the
    decoder with full frames. For h264, require that we are aligned on access
    units.
