Comment (by ronag):

 Can't say I fully understand how the dnxhd_parser works. But it looks to
 me that if you are unlucky you could hit a data byte that matches the
 prefix.
 https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/dnxhd_parser.c#L62

 Also once {pic_found == true} don't we already know the offset to the next
 header? Why look for ff_dnxhd_check_header_prefix?
