4k movies with direct play problem

[hspantera 8]

I hame 3 lg smartv in my house and in direct play 4k movies some of them it stutters or don’t shhow subtitles. The problem is that if it stops at minute 1:43 if I try 20 times same movie it alway stops at the same point. This happens with all movies that have this problems. Stuttering stops . Local 10gb infrastructure cable. Strange is that on Samsung tv android tv iPad iPhone all works fine with none of this problems. Only in lg tvs. I have 3 in my house and same movies stop at same time exactly. So the problem seems to be something with app. 1080p works fine. Thanks.

Can you please post media info and log files for this example?

But my suspicion is that you are trying to play DTS or TrueHD audio tracks which is causing transcoding and your server probably can't keep up, or you are trying to show PGSSUB subtitles which requires burn in.

No. Ac3 áudio and direct play. No subtitles. But only do this on lg tvs . I have Samsung with same files and works fine. Android tv too. It’s random 4k hdr or Dolby vision movies. It works in other platforms. Every platform. Only on lg don’t work well. And it’s strange because it’s on same specific times on 3 tvs that I tested that happens that. If one movie stops at 10minutes. I tested in the other two and it stops at same time. So every error that are happening it’s the same in all lg tvs. Strange that same movie works well on every other devices.

I have 10giga infrastructure.. everything flies. Direct play always. Only lg tvs it’s happening that. The files are ok. It works on every other client. Only on lg that this happens.

Just because you have a 10G LAN, does not mean your LGs will ever see close to that.  The bottleneck with just about any TV is the ethernet port (100mbps but in actuality, about 90 is the most you will get).  And with the USB to ethernet adapters out there, they are wonky at best (one test, you may get 300mbps and go WOW!  Only to test again and maybe get 50mpbs).  And Wifi is a bigger issue than hard-wired connections due to interference and other issues with a wifi network.  Some 4k movies will work ok but others will fail due to their bandwidth requirements.  There really isn't anything that can be done.  TVs just can't deal with streaming a good 4k movie when it's hitting 85+ mbps.  That said, the LG app works just fine given the above limitations on my G4 OLED.

Mediainfo and logs please.  Are the TV's on WiFi or cable ethernet?

[hspantera 8]

Everything with cable. And why don’t work on all movies in lg and same movies works in Samsung tv? If the problem was the server or the infrastructure it should had the same problems on Samsung tv and appletv. Hás  I said everything works great in all devices. I just posted because I have 2 lg qned and 1 lg oled and only the lg tvs has this problem. And I even can stream remote for my other house to a Samsung tv 4k hdr direct play with no problems. Has I said I have internet download and upload 10gb. All my switch’s are 10gb. It’s curios that only on lg tv this happens. And more strange is that the glitch’s and the stops happens exactly the same on all 3 lg tvs. So it’s some kind of Emby client for lg that don’t like direct play 4k.

You've got a bitrate limit set somewhere, so the server should be transcoding the video, but you've disabled video transcoding so it's just copying all the streams to a new container and trying to DirectStream (and ignoring the bitrate limit) which is all a bit pointless and probably causing issues.

First, please try and find where the bitrate limit is being set and remove it if possible.

Then, I would try enabling transcoding for video playback in the user profile so that the server can work the way it should be. With it turned off, you will introduce other issues and it will make it hard for us to troubleshoot.

Is the server remote, or is it on the same local network as the TV?

Keep in mind that you are trying to play a >60Mb/s file, and the TV's network port only supports 100Mb/s.  There is overhead in the network transmission process, so you a probably getting close to the limits.  A good WiFi signal will actually support higher rates than ethernet.

Finally, you are trying to play files that exceed the TV's specifications.  That doesn't mean that it won't work, but you need to be aware of the limitations.

Is the client hard coded with 7Mbps fallback for remote connections on AUTO?

I was using localxpose tunnel and that’s seam to be the problem. With direct local ip or dyndns for remote it works fine. Strange is why only this was happening on lg tv. And in other apps was working. Thanks for the atencion. Can mark this one has solved.
