Movie transcode issues 4k HDR - LG C9

[esskaa 0]

Hello, 

 

I am very new to EMBY and 4k videos. I have a problem playing a movie file, with unnecessary transcoding to be exact.

The reason for transcoding seems to be: "Media bitrate exceeds limit" - normally I use Auto, but I tried 4k 120Mbps aswell with the same result.

Original Media Info shows: 20.2 Mbps

I cant find anything in the log files.

 

From my point of view, there has to be a problem with the LG app.

 

- The movie works without transcoding or any other issues with Plex on the same TV.

- The movie plays without transcoding on my iOS devices

- I do have movies with higher bitrates that play without transcoding on the TV

 

Please help me, am I missing something or is my assumption correct?

 

So long,

EssKaa

Hi, it looks like this one tried to direct play, the LG video player reported an error with the file and so we automatically switched to transcoding in order to ensure it would be playable.

So the Plex App is using a different player than emby?

The file seems to be ok using any other app.

Any hints what the source of the problem is?

Even remuxing the whole thing did not help.

If you copy the file to a USB stick and play with the Native LG Video Player - does it then play ok ?

Yes this would be a useful test. Thanks.

Good point! Sadly the internal player just says: File can‘t be recognized.

So no, it won‘t play. Funny thing though, the TV generates thumbnails from the file itself and they are perfectly fine.

The Plex App has to do some kind of modification or simply use its own player.

.. yes, so I guess Plex doesn't use the built in LG App but Emby does which results in this behaviour, confirmed as the USB won't play either.

 

tbh - I've had no issues with the LG/Emby App playing my 4K content at all - have you compared all the detailed 'Profile' settings using something like MediaInfo on the file in question vs others that work ok ?

 

The reason I ask, is for h264, if the 'level' is set too high, then the player rejects it even though the video could have been set to a much lower level.    I'm not sure why Emby reports the h265 'level' as 150 or 153 (in my case, for my 4K files) but these are the levels :-

The higher levels are for 4K/8K 60Hz plus and need huge bandwidth which might be what the problem is .. ?

I'm pretty sure it's not possible to have a custom player with the LG SDK. I think they are probably just doing a remux/container swap and you are not noticing it.
