MKV files do not play Dolby Vision, but MP4 files do

[podonnell 47]

Hello there,

New user, coming over (possibly) from Jellyfin. I've had a ton of player issues with JF so I'm evaluating Emby.

One thing I am seeing right now is all my MKV files will not play Dolby Vision, they fall back to HDR. I know I would sometimes see a Remux from Jellyfin, but I don't know if that was all the time with MKV files.

Anyway, hoping this is enough information to help figure out how I can get my Dolby Vision working -- I have ~20 DV titles, only one of them is in MP4 format.

Thanks!

Need specific examples along with server and ffmpeg logs.  But usually comes back to the DV profile as 7 is usually the issue.

This was the most recent test I ran. This one is Profile 7 but it plays in Dolby Vision just fine with Jellyfin. I also have a bunch of Profile 8 titles that do the same. I tested all 20 titles and the sole one to play was .mp4 with the following media info.

Same issue.  You can attach then here.

Sorry, no idea why pastebin is doing that. I use it all the time.

Attaching them here. The server log is for another title that is Profile 8

Hmm, for that title I can see both Audio and Video show 'Direct Play' in the stats for nerds.

I see it is two different clients looking at the same content as the limit applied to Chrome while the other is LG Smart TV.

Hmm.. The LG Smart TV should be where I was watching from. The Chrome client I was attempting to pull logs, maybe it snuck in there as I was poking around.

[podonnell 47]

Does anyone know if I have control over the ffmpeg command that is executed when I play a title? I've found an ffmpeg version and command that I'd be able to use that would remux for me on the fly. Or is this not possible with Emby?
