HEVC Rext Profile not direct playing.


Recommended Posts

Posted

It can direct play using external players like vlc and mpv. But using emby latest version it forces a transcode.

Hi there, did you explore the stats feature in the video player to learn why it was transcoding?

Hi, its using yuv422p. Its an anime show, so hdr is not important. Why can vlc and mpv play it but not emby.

mpv external player can play it flawlessly. Add back libmpv. Maybe that will solve it.

I do not think the player support the Rext Extensions. Maybe @Luke or @ebr can confirm?

Mpv works. And they were using libmpv before so i don't see why it wouldn't work.

By default that profile is not supported by Android.  

Supported media formats  |  Android Developers

Unless there are other documentation

Now from a external player standpoint it should work.  Not a Android user but isn't the beta app using mpv?

Posted

Do you have that apk i can try? Couldn't find the beta anywhere since it's closed source. 

If libmpv uses the same player as mpv, i don't see why it wouldn't work since mpv is open source. But there's no toggle to change players from exo to libmpv.

I would look in the Testing Area in the Android section.

Still can't find it. Hope you guys add a toggle to use libmpv.

Android uses ExoPlayer.

It was using libmpv previously. Jellyfin can't even use libmpv due to no man power. Why not just use libmpv.

It's not a question of libmpv or not. What we're doing now is superior to using libmpv. Thank you for your patience.

mpv external player can play direct play though. And since libmpv is related to mpv, why do you say exoplayer is superior?

It's not that it's superior by itself, it's what we've done with it. See all the testing threads on the testing area over the last few months for defaults.

The Emby team has done a lot of ExoPlayer customizations.

Still doesn't explain mpv external player works much better than exoplayer.

 

Why not just use libmpv and optimize it to play just like the mpv external app?

Posted

We thank you for your patience.

It doesn't.  As Luke already said:

Keep in mind Rext isn't very common at all outside of Anime. I don't know why but it seems the people putting out Anime go out of their way to always use the "latest/greatest" everything regardless of compatibility.

I'd better keep an eye open! It's not one I've come across yet, though your point is proven by the fact that a lot of my anime is main10 profile, which already causes transcoding on some clients.

REXT is likely used in anime to gain detail. This video is 4:2:2. All of the REXT videos I have are 4:2:2 (but none of them are anime). Just about all other videos are 4:2:0. Anime has more definitive edges than live action, so that would be my guess.

Posted

Comparing 4:2:2 to 4:2:0 doesn't add more detail. It rather adds more fine-grained color values which makes zero sense for cartoons or anime....

Though, I don't have any plausible idea why they might be doing like that.
