Does Roku support HLS version 4 ? or will it ?
Specifically would like to have #EXT-X-BYTERANGE

[RokuMarkn]

As far as I can tell, EXT-X-BYTERANGE is currently supported (although I haven't tested it). Can you describe what problem you're having with it? I think we're currently supporting version 8 of the HLS spec.

I just tried a test and it wasn't working BUT it most likely is me.
What I tried is a hard coded sample from Apple's dev site, but instead of length@offset, I just gave it length which is supposed to be accumulative.
#EXTM3U
#EXT-X-TARGETDURATION:11
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-VERSION:4

#EXTINF:10.0,
#EXT-X-BYTERANGE:188000
media.ts

#EXTINF:10.0,
#EXT-X-BYTERANGE:188000
media.ts

#EXTINF:10.0,
#EXT-X-BYTERANGE:188000
media.ts

Need more research.

[greubel]

Ok, gave it another shot.
Changed the first two requests to:
#EXT-X-BYTERANGE:188000@0
media.ts

#EXTINF:10.0,
#EXT-X-BYTERANGE:188000@188000
media.ts

Here is what is logged:

Any reply ?

[RokuWimM]

Roku level 3.1 does not support EXT-X-BYTERANGE tags but firmware version r5.04 does. However since firmware version r5.04 does not support all HLS version 4 features it will reject any playlist that has "#EXT-X-VERSION:4". Can you change the version number to 3 and keep the EXT-X-BYTERANGE in the playlist.

Roku level 5 never tried to access the media file, Roku level 3 did.
There wasn't any requests for byte range in the server side logs.

So I guess this is a lost cause. Need to try something else.

We just discovered something interesting related to this so I thought I'd share.

Our old Roku XD (2050) will play an HLS declaring version 4, but our Roku HD (2500) would not. If we manually adjusted the version number down to 3 in the m3u8 playlist, it would instantly work on the Roku HD.

Our best guess is that because the XD is so old, it doesn't know what to do with the version tag. However, the HD, for some reason, only supports up to 3, and that's why it would not play version 4 m3u8 playlists.
