lavc/utils: add VP6F hack for setting correct video size in stream
For some obscure reasons avcodec_set_dimensions() resets the
width/height
so that the resulting value set in the stream is equal to the
corresponding coded_width/height, which is not the same as the correct
width/height in case of the H.264 and VP6F codecs.
This adds a codec-specific hack for VP6F which disables the call to
avcodec_set_dimensions() in avcodec_open2(), like it is done with
H264. A
proper fix needs to be found yet.
Fix trac ticket #1386.
Based on a patch by Michael Niedermayer.
