4k dropping frames

Recommended Posts

Mbedford

Hi all,

 

I have a fairly beefy system spec wise for a media center I think, with a i7 CPU and onboard Intel UHD graphics 630 chip which is marketed on the Intel site as supporting 4k playback.

 

But for H265 4k content im dropping frames (see attached screenshot), im trying to work out why.

 

H264 4k content is playing smoothly and not dropping frames (see attached screenshot), but they are very large files. Looking at the CPU usage its WELL below 100%. Looking at the disk usage in task manager seems pretty low, another reason I dont think its the disk performance is H254 files are much larger, so would be more dependence on a high performing disk.

 

FYI 4k videos on YouTube is smooth. VLC player drops frames also for H265 4k content.

 

Any idea why iys dropping frames when the system seems to be up to the spec required?

Are you playing this using Emby Theatre on the same machine that is running the server?

 

Not saying this is an issue. Just fact finding.

 

Are you physically noticing the dropped frames with your eyes?

 

Have you tried to force a transcode by lowering the bitrate?

 

Have you tried playing the media on a different client?

 

Need to get @ or someone with MPV knowledge to comment on the reasons for dropped frames showing in SFN.

Thanks for your reply.

Are you physically noticing the dropped frames with your eyes? < Yes, very slightly, as its not dropping LOTS of frames, as you can see form my 2 screenshots, but its noticeable alright.

 

Have you tried to force a transcode by lowering the bitrate? < Don't know how to do that sorry. But shouldn't it just play with my current hardware/software setup?

 

Have you tried playing the media on a different client? < Yes on VLC player and it drops frames also, in fact I think Emby theatre drops a few less frames, maybe its decoder is a bit more optimised.

So when you used VLC that was just direct from file? You were not using it as an external player in emby?

 

Have you tried playing on a phone or other networked device?

 

I will see if I have or can download those specific rips to see if i see anything different.

slow rising dropped frames is in first a good sign that the gpu is not totally overchallenged

 

"4k videos on YouTube" is not a good comparison cause there are different videocodecs and fps possible

 

there are different causes possible, the first i would try, is setting a "better" display refreshrate, 23p media on 30hz especially without display sync, could cause this

if not possible, i would try activating display sync and interpolation

 

totally overlooked that h264 files don't drop frames, so this ^ shouldn't be the cause

Are you running a custom MPV.conf file?

Change your display resolution to 3840 not 4096. You're forcing the player to upscale from 3840 to 4096

That looks like a good catch!

that should not really count in here, height is the same, so there should not be any upscaling

and running a display below its native res is nothing you should do

He's also stretching the width, as the height doesn't change. Windows will recommend the resolution to be 3840 x 2160.

seeing some black bars on the left and the fact that mpv does not stretch out of the original aspect ratio in the default config, i dont think there is some upscaling here

 

we have just too much useless und too less usefull informations here

 

a shot from the video settings page in ET could be usefull

Here you go, I hoe you mean this options screen:5e967b4f32aa7_settings1.png

Everything is unticked and left default. I haven't hacked up pretty much anything in Emby, its all pretty much default settings throughout.

I would guess it’s the refresh rate mismatch...

I would guess it’s the refresh rate mismatch...

but then there would also be dropped frames with h264 content

not saying that this should also be corrected

the important part high quality profile and interpolation (the last two settings) is missing :)

but i guess they are unchecked as said

 

as shot in the dark, try setting hardware acceleration mode to Auto (copy back)

Thankyou for your help by the way. :)

 

Preferred Refresh Rates: blank

Enable video display syncing: Auto

Enable OpenGL high quality profile: unticked

Enable interpolation: unticked

 

Screenshot attached of 'stats for nerds' with Auto (copyback) enabled with a 4k H265 movie, still dropping some frames. H264 still not dropping frames.5e96dcb6eb93b_WithAutocopybackenabled.jp

 

Not sure if this helps, but running Emby in Chrome instead of Emby Theater gives the same dropped frames result.

and also same result in VLC player.

if all players drop frames by 4k h265 10bit than the GPU simply can't handle it

 

if the CPU can, you could try setting hardware acceleration mode to none to cross check

Hi, sorry for delay.

 

I set the acceleration to none, it dropped very slightly more frames than when set to auto

 

When set to auto it says video renderer is GPU and hw acceleration d3d11va

I have the same observations, even when I set display to 24hz movies will still drop and gpu is running 60% load. Stats for nerds says d3d11va Hwa and media and display are 23.xyz FPS. Similar result when I change to copy back and gpu load drops lower but still drops

Yeah what's strange about all this is when you go to task manager and look at the GPU load or CPU load it's not freaking out, my GPU load is lower than yours and I'm still dropping a few frames, it seems 3 to 5 frames a second I drop.

I run a customer MPV.conf file.  Maybe this will help you out.

Try removing your scale and cscale options and see what happens.
