Validate codec of stream to be muxed except for data muxer.
What issue does your patch fix?
Had an user on SE sometime back extract a video stream to a .h264 (in
order to retime PTS). The retiming didn't work since the stream was
actually mpeg4 but the muxer hasn't complained. Might have been fine but
ffmpeg's format probe settled on h264 so user couldn't proceed until we
examined the source. So just added some basic checks. Initially strict
but loosened due to Michael's feedback.
Users can still use data or rawvideo muxer to extract any random stream.
(I do see that rawvideo does not enforce a single stream. Why?)

Gyan
