Good day,
My task is to stream video natively in application.

I receive following m3u8 file from API :

#EXTM3U 
#EXT-X-VERSION:4
#EXT-X-TARGETDURATION:15
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=600000
video-2.mp4-600k.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1000000
video-2.mp4-1M.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=2000000
video-2.mp4-2M.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=4000000

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=6000000
video-2.mp4-6M.m3u8
#EXT-X-ENDLIST

I tried to add URI in demo application and i receive following errors :

But if I remove following lines from m3u8 file, video streams :

#EXT-X-VERSION:4
#EXT-X-TARGETDURATION:15
#EXT-X-MEDIA-SEQUENCE:0

This is working version on file :

#EXTM3U 
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=600000
video-2.mp4-600k.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1000000
video-2.mp4-1M.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=2000000
video-2.mp4-2M.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=4000000
video-2.mp4-4M.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=6000000
video-2.mp4-6M.m3u8
#EXT-X-ENDLIST

The question is, can I ignore somehow this meta? And why does it produce such errors?

As per the HLS specification, EXT-X-TARGETDURATION and EXT-X-MEDIA-SEQUENCE are tags that should exist only in media playlists, not in the master playlist.

ExoPlayer automatically detects the type of the playlist being parsed based on the tags that it sees. Since the playlist contains tags that should only exist in a media playlist, we assume that's what it is. Playback then fails because it is in fact a master playlist that contains spurious tags.

The solution is to fix the source media to adhere to the specification.
