This avoids blocking for a long time in
avformat_find_stream_info while waiting for a codec to be set
for data streams in MS-RTSP streams, where the codec won't
ever be set.
This is an adaptation of one part of commit 4c050429780b0d
in FFmpeg.
Alternatively, we could just ignore data streams in MS-RTSP
and not pass them through to the caller.
