Note that this is _not_ documented, the only places that mentions
restrictions on linesize is the avcodec_decode_video doxy and that only
talks about line size. The avcodec_encode_video function does not
mention any restrictions.
And to whoever copy-and-pasted the avcodec_decode_audio2 doxy: It would
be a good idea to actually read that stuff, the part talking about
"linesize" does not make any sense there.
