When i validated the VOD playlist with media stream validator, am getting the "Different target durations detected" error for trk vs sub, var vs sub playlists,
Error: Different target durations detected --> Detail: Target duration: 3599 vs Target duration: 6 --> Source: subs/eus_2/playlist.m3u8 --> Compare: trk969287/playlist.m3u8
--> Detail: Target duration: 6 vs Target duration: 3599 --> Source: var969287/playlist.m3u8 --> Compare: subs/eus_2/playlist.m3u8
but the apple specification (https://developer.apple.com/documentation/http-live-streaming/hls-authoring-specification-for-apple-devices specification) stated that "5.7. For VOD content, target durations of subtitle playlists MAY be longer than the other media."
Can you please clarify the query that why we are getting different target duration error for subtitle vs other media playlists even though the apple spec mentioned that the subtitle playlist may be longer than other media for VOD assets?
