Playback lagging

[zfrenchy 12]

Me again, I am getting frustrated with Emby ...

 

Yesterday my internet was down, I choose to watch a movie on Emby, but the experience was horrible !

 

Lagg like crazy, only low resolution movie pass, nothing HD or UHD.

 

The processor in my UNRAID server goes 100% !!!!

 

Please help me find what is wrong ...

I downgrade the playback to 480p1mbps, processor run at 98%, still choppy

[zfrenchy 12]

Please note, I never add this problem before I update my UNRAID server, and re-install Emby after a tons of problems (see my other posts).

 

Same hardware, same LAN, same players (LG tv, or my main PC)

Since you're burning in subtitles, try turning those off prior to playback and see how that compares.

[zfrenchy 12]

disabling it in the transcoding ?

[Luke 42079]

On the video detail screen prior to clicking play.

Not according to your example log that you provided. Can you please show a screenshot? Thanks.

[zfrenchy 12]

no subs option in the page of the movie

 

[Luke 42079]

OK i was looking at the first log example, which was 88 minutes.

[zfrenchy 12]

88 is a low res movie, no problem with it.

amything else, HD, UHD do not pass

[zfrenchy 12]

The ffmpeg log was cut off so don't know the overall converted bitrate but bitrate doubling happens converting 79Mb HEVC to almost max 140Mb.

-c:v:0 libx264 -g:v:0 180 -maxrate:v:0 139808000 -bufsize:v:0 279616000

So if you set the client to a lower playback quality do you get the same result?

[Luke 42079]

Did you see this?

 

[zfrenchy 12]

@Luke  My hardware acceleration is enabled in Chrome, The LG tv don't have the option.

@Happy2Play  Watch my YouTube video, you will see lower the resolution or bitrate do not change much of the playback

 

What can I help you guys, what do you need ?

[zfrenchy 12]

I was able to playback a 4k Movies 120Mbps

here the media info

 

Then here is a movie I cannot playback

[zfrenchy 12]

I found why my movie are RIP in HEVC (H265), because these movies are HDR, other non-HDR are RIP with H264.

 

NOW THE MILLION DOLLAR QUESTION :

I ordered an new graphic card for the UNRAID server GTX1660Ti

https://www.newegg.com/asus-geforce-gtx-1660-ti-tuf-gtx1660ti-o6g-ev/p/N82E16814126538?Item=9SIAWKTHU71967

 

With this card, can I enable the hardware transcoding for Emby and fix the problem ?

I don't want to re-encoding all HDR movies, which I don't know how many ...

[zfrenchy 12]

doing some test and find that ...

 

Playing the 4K movie 1917 (H264) in 4K120Mbps run the processor at 10% ... GREAT !

But playing the same movie at lower than 4K80Mbps run the processor at 90/100% ... WEIRD !!!

Hi.  Because your server is converting it to the lower bitrate on the fly.
