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?

When i validated the hls playlist with media stream validator, received the below error
You MUST include the AVERAGE-BANDWIDTH
As referred to in the Apple specification, the AVERAGE-BANDWIDTH attribute has been introduced in the HLS protocol version 7 onwards only, but we have received this error (in media stream validator) for playlists that have the HLS protocol versions 3, 5, and 6 (mostly for all the playlist versions) also. This looks contradictory between apple spec and media stream validator result.
Could you kindly review and clarify?
