LG C4 Emby App issues?

[alex77777 18]

Is anyone having playback issues with the LG C4? Every other device works fine but for some reason the LG C4 is in a constant buffer even though it is doing direct play. Emby Server and the Emby App are on the latest versions.

If you're seeing constant buffering during direct play, then this is most likely a network/throughput issue.  Make sure that you not trying to play crazy bitrates (ie: > 50Mbps) and if on wifi, make sure that it hasn't fallen back to a 2.4 GHz connection

Ok that is a good point, I will test if wiring the TV will be any different. Thanks for the suggestion. Most of the media I was testing was around 24mbps

I have the same issue since a few weeks on my C8.

Nothing changed in my network, i have evertyhing wired.

Emby clients on other devices still work fine.

I believe i have had an update few weeks back, then the issues started.

What emby server and app version are you on?

Can you also confirm the playback type (DirectPlay, transcode) in Stats for Nerds when you have this issue?

Just happened again, while it less than previous days (only once an hour now). 

Took a picture of it. 

Seems to be Direct Play.

Thanks. The issue is that when it is Direct play and no form of transcoding is involved, then in reality, the app is just giving the TV the url of the original file and then the file is being played directly. There is really nothing that the app can do to influence that playback performance either negatively or positively. It comes down to server, disk, network performance to ensure that the file is being served as fast as required for playback. 

It doesn’t look like you are playing high bitrate files, so throughput shouldn’t really be an issue. But if you are running other processes such as PiHole, ad blockers, reverse proxies, etc the this might also be impacting performance. If you haven’t already, try rebooting all your routers and switch gear, then try and reduce all the load in your network and on your server, even temporarily to see if you can get to stable performance.

Restarting the router fixed the issue it seems. Thanks for the help

Thanks, this is good information.

I guess my tv buffers the stream, then my NAS goes into idle mode. Then when the buffer gets empty, it starts the disks up too slow. Could this be?
Does the LG tv app have logs where i could identify why it buffers?

The TV buffer isn't that big, minutes at the very most. Your NAS shouldn't be going into idle that quickly. As per alex77777's comment, have you tried restarting all your network devices and maybe rebooting your NAS to see if that helps?

hmm there goes that theory..
Yeah I've rebooted everything few times last few weeks.
Still keeps buffering (at least) once every hour for about 60 seconds.

Sounds a bit odd.  To confirm your original theory, as a test can you prevent you NAS from sleeping? 

Does the NAS or any other connected device have a scheduled job that runs hourly? When it occurs, can you check the processes on the NAS to see what's running?

Its a very old Readynas 1500, i should have replaced it long time ago.
But hey, it still "works".

I have changed the "Enable disk spin-down after" from 5 to 30 minutes of inactivity.
Hopefully that helps.

Maybe I need to have SSH open with top running while watching my next movie.
