Everything was okay - Until I changed to 4K Content

[hErEsy 4]

Hi Folks,

 

 

sorry to bother and probably a 1000 times happened already. I saw a few posts - but didn t help me.

 

After switching out my content to 4K (30-50GB)- and before you ask why (the answer is: because I can - nah just wanted to try it out)

I cannot watch it. It is lagging every 5 Seconds for roughly 4 seconds

I am running W10 up-to-date. Drivers - up-to-date.

Quadro P5000|XEON e3-1575 v5|64Gb -> so performance shouldn t be the issue. All drivers updated. Grafx drivers original Dell

The Client is usually a Samsung TV (Tizen) or a Philips TV (Android) -> The Philips usually suck more via Wireless. Everything below 4K has no issues.

 

From the logs I gather (not sure though) that somehow only the internal Intel GrafxCard is beeing used. Not sure how to make emby start using the 3D Grafx Card. Help is much appreciated.

After making Windows / Emby use the P5000 - I still have the lagging issue. AAAAnd now I am fresh out of ideas.

Hi there, as a test, if you disable hardware transcoding in server transcoding settings, does that help?

Trying to play a 4K Remux via wireless is possible but needs the very best equipment (not the ISP provided 'router') and a strong wifi-signal.

Remember, you've gone from say 8Mbit/sec for average 1080p content, to 80Mbit/sec for a 4K remux - a 10x increase !

The pausing is simply your device waiting for data to be delivered.  

If you have a long Ethernet cable, then it is worth just trying this to see if the issues is resolved - if it it, then you know it's bandwidth related.

On wifi- Try switching to 2.4Ghz if you can (slower, but stronger) or maybe other channels on the 5Ghz.

Hi,

sorry for the late answer. No excuses - I even work from home

So, Turned HW Acceleration off as you said and voilá , works like a charm. SO, does that mean I cannot brag about the P5000 anymore? Is it a driver issue? (before I switch back to Dell Driver or nVidia, I would like to know how to troubleshoot further)

(btw. not so important if we don't get it working now (I am sure there are bigger fish on your plates than I am) - this is just about the "Star Trek"-effect. If it can do it, I´d like to raise the effinciency and get to know my "Emby-Rig" better (Setup-Next-Next-Finsh doesnt cut it for me anymore and I´d like to customize it a bid more now(but half the stuff I hear sounds more like the contents of my wifes cabinet then IT ;), so I´ll have loads to learn #bepatientwithnoob)

 

As to HW:

It is a AVM Fritzbox which is not ISP supplied crap and Bandwidth is no issue ;).

 Is it a driver issue?

Best way to find out is to try both and see how they compare.

Do you have have 'throttling' turned ON in the Transcoding options ?

Unless this is turned on - The P5000 is going to TRY and transcode as much as it can as fast as it can - thus other areas of your computer become the bottleneck feeding it data to the detriment of streaming.

Even if throttling is on, your transcoding needs to be fast enough so that throttling can actually happen in the first place.

[rbjtech 5284]

Yep, appreciate that but with the spec of this machine - there is no reason to doubt it has enough power.

"Quadro P5000|XEON e3-1575 v5|64Gb"

As softworks has explained in other threads, as the P5000 is a beast of a h/w transcoding card and with throttling turned off - it will consume all the I/O it can, bringing the system to it's knees in the time it takes to transcode the entire file.  Thus my point about ensuring throttling is on to allow the system to 'burst' transcode instead to meet the streaming demand.

I have no idea why you guys need so much bandwidth with 4K movies.

See picture

 

[rbjtech 5284]

There is a BIG difference between a 4K remux (Source = Raw 4K UHD Disk) and a 4K 'streaming' bitrate.

On your phone or a low end small TV, you may not see the difference.  On a high end system with proper HD sound - the difference is night and day.

This media is played on Android TV 4K both from the Philips and Sony brands (OLED). The sizes are 49 "and 55" screens.

If you want to try and see what quality my films give you, I can give you access to my 4K library.

 

[rbjtech 5284]

Hi - Thanks for the offer, but it is technically impossible to compress a 80-90 Mbit HEVC file (which has ~30% better compression than H264 anyway) into a 6Mbit h264 file with comparable quality.  

Netflix use 15Mbit HEVC for a reason - and even that is poor and shows macroblocks during fast paced action and is not HD Audio.

There are entire website and forums dedicated this topic - see doom9.

If you are happy with the quality - great - I'm just answering your question about why other people have difficulty streaming 4K remux files as they are choosing to try and playback uncompressed versions of the original UHD disks in all it's professionally authored HDR/Dolby Vision and HD Audio quality/glory - not some bit starved streaming copy or worse.

So you are judging something that you have not seen yet? What you want to achieve you can only achieve on a local network or a 1Gbit fiber network with at least 40mb upload speed. So if you want to comment whether it is good / bad quality or not, check out my 4k library and try a movie.

I dunno if we're judging.  Math is judging.  As @rbjtech noted, what you're proposing is impossible.  It sounds like you're happy with your video quality and that's great.  That doesn't change the fact that it's much, much lower than the source data.  You can't eliminate 90% of the video data plus convert to a less efficient codec and get comparable results.

4K video rips are 50-100Mbps for the video stream in my experience.

Your movie is an overcompressed, H264 encode.  It has no HDR, nothing that makes it better than a 1080p encode.  In fact it is bitstarved.  You would be better served with a high bitrate 1080p encode, which the original source for this movie has.  All you've done is created an oversized turd.  If you're going to attempt to shrink something this much, use HEVC of AV1 as they are designed for this use scenario, AVC/H264 is not.

I stick with it, see and then judge.

This reminds me of my mum who thinks SD looks great  

I have my transcode remote setup at 20Mbps ... And locally is high as possible for my devices that need transcoding. My remote family noticed heaps when I upped it from 8 to 20 and it wasn't placebo effect since I didn't tell them they commented on their own about increase in quality. Of course I'm lucky to have gigabit fibre so can have it that high for remote viewing

Does it, though? I have an ISP-provided router and have no issue watching most of my 4K content on Emby. There have been a couple that have stuttered, but I'm not sure if that's specific to the files, or Emby was busy doing something else simultaneously, or what.

Depends if your ISP was the few that aren't tight asses... But most will give a shit router compared to what is out There

This is the key point - if nobody else is using the ISP wifi - you are probably ok, but it's when you get multiple devices (ie 10+) the ISP hardware is not designed for this and simply craps out.  Decent prosumer AP's such as Unifi are designed for 100's of simultaneous connections, thus they don't break a sweat when you use them in a home environment and can handle multiple 4K streams without issue.
