While validating a Dolby Vision Profile 5 playlist in CMAF format (with segments in MP4), the Media Stream Validator reported the following error in the MUXT-FIX-ISSUES list:
However, the playlist correctly specifies Dolby Vision Profile 5 in both the EXT-X-STREAM-INF and EXT-X-I-STREAM-INF tags.
Playlist: #EXTM3U #EXT-X-VERSION:8 #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio-ec3",LANGUAGE="und",NAME="Undetermined",AUTOSELECT=YES,CHANNELS="6",URI="var14711339/aud1257/playlist.m3u8?device_profile=hls&seg_size=6&cmaf=1" #EXT-X-STREAM-INF:BANDWIDTH=14680000,AVERAGE-BANDWIDTH=14676380,VIDEO-RANGE=PQ,CODECS="ec-3,dvh1.05.06",RESOLUTION=3840x2160,AUDIO="audio-ec3" var14711339/vid/playlist.m3u8?device_profile=hls&seg_size=6&cmaf=1 #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=1419881,URI="trk14711339/playlist.m3u8?device_profile=hls&cmaf=1",VIDEO-RANGE=PQ,CODECS="dvh1.05.06",RESOLUTION=3840x2160
Could you please review this and clarify:
Why is the Media Stream Validator reporting this error, even though the playlist correctly includes Dolby Vision Profile 5 parameters in CMAF format?
Why is this error not reported when using a playlist with TS segments instead of CMAF (MP4)?
