Okey, this is more of an RFC. It's not tested against the situation that
was the reason for the first patch. (I can't seem to remember what sample
file i used to track it down).
The issue was nothing major, it was just wasting time in
av_find_stream_info which was explicitly noticable if you played a live
stream wich has limited throughput.
The thought here is that, if we are not probing and have CODEC_ID_NONE. We
won't get any more codec information than we already have.
