Only copy it manually in the muxers where it makes sense (rtspenc, sapenc). Don't touch the original AVStream in movenchint, where the original AVStream should be kept untouched. This fixes the normal tracks in RTP hinted files afterabb810db- the hint tracks were ok while the normal media tracks were broken, noticed by Michael Niedermayer. This revertsabb810dbbut achieves the same effect for the other muxers. Signed-off-by: Martin Storsjö <martin@martin.st>
