libavformat/rtpenc_mpegts: check avformat_new_stream() return value The function avformat_new_stream() returns a NULL pointer on failure. However, in function rtp_mpegts_write_header(), its return value is not validated before it is dereferenced. Check the return value against NULL to avoid potential NULL dereference.
