Subject: [PATCH] avformat/dashenc: only write video streams into HLS master
playlist
Tool mediastreamvalidator reports error "Variant media_[N].m3u8 is
missing audio group" for audio streams in HLS master playlist. As audio
streams are already listed in audio group, skip them as variant media
streams in master playlist.
