libavformat: Use avcodec_copy_context for chained muxers
This avoids having the chained AVStream->codec point to the same AVCodecContext owned by the outer AVStream. The downside is that changes to the AVCodecContext made after calling av_write_header cannot be detected automatically within the chained muxer. This avoids having to manually unlink the chained AVStream->codec by setting it to null before freeing the chained muxer via generic freeing functions. Signed-off-by: Ronald S.
