Best settings for 4K HDR playback?

darren1963 · March 16, 2017 at 2:12 PM

Thanks for the responses chaps. It must be something my end then, as I have x 3 Nexbox A95x S905X boxes and all 3 freeze when trying 4k movies. Yet if reinstall SPMC on android they play 4k perfect. Weird.

If you're using NFS, I would recommend to try to mount NFS at the OS level (Mounting network shares - OpenELEC).
Without changing anything and using the same NFS server, I get sluggish performance using the native NFS implementation in Kodi while it works perfectly if I use the same server at the OS level.

Something similar: NFS (libnfs) Performance

R4W,

Thanks again for reminding us to do this. I really learned the hard way on this one. It would sometimes work but always give me problems when I reflashed the new ROM. This always works perfectly without messing with it for hours. I'd suggest anyone else with mysterious buffering issues, don't be stupid like me, do like r4w says first.

I'm mapping the shares on OS level, but no files are listed inside the folders. I checked my NAS and permissions look OK, created a new share just in case, I can access the shares from my Windows PC and my Android phone, and I can access them on Kodi/LibreELEC via SMB or UpNP, but not NFS.

I'm currently automatically mapping them at boot. I tried to use # mount -t nfs 192.168.0.9:/Movies /storage/movies2/ -o nolock via SSH and it returned an error which is probably the cause of the issue:
mount: 192.168.0.9:/Movies failed, reason given by server: Permission denied
mount: mounting 192.168.0.9:/Movies on /storage/movies2/ failed: Bad file descriptor

The IP for the NAS is correct and so is the share, but even if I change that to an incorrect one it doesn't make any difference and I get the same error.

I'm not a Linux user so any help is welcome.

Syntax is OK
Did You create the local folder /storage/movies2 ?
Is 192.168.0.9:/Movies the full path to folder on NAS ?

command to mount my NAS

Code

mount -t nfs 192.168.0.41:/c/backup /storage/mnt -o nolock

where 192.168.0.41:/c/backup is full path to NAS-share and /storage/mnt is local folder on my box

check:

Code

Krypton-Box:~ # mount|grep mnt
192.168.0.41:/c/backup on /storage/mnt type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,nolock,proto=tcp,port=2049,timeo=70,retrans=3,sec=sys,local_lock=all,addr=192.168.0.41)

I ended up giving up on LibreELEC and going to an Android TV build for proper HDR support.

Pros: HDR/10 bit output/colorspace switching actually works with an Android TV port and spmc. It looks indistinguishable from my internal player.
Can use some Android TV apps as spmc launcher shortcuts.

Cons: No resolution switching, so dealing with poor upscaling on anything that isn't 4k.
Brightness bug is back on boot.
Needed to root and use PassthroughFix.apk to fix passthrough clipping.
SPMC is currently only available as a Jarvis build.

I'm very tempted to use separate boxes with LibreELEC and Android on different inputs so I can have proper HDR/10bit output/colorspace switching, and also resolution switching for decent upscaling.

Thank you for your reply All paths were correct and I tried all sorts of combinatons. Seems that it might be something to do with my NAS setup.

I was able to get it working using cifs and shares are properly mapped at reboot. Hopefully that should take care of the bandwidth issues for me.

BTW:
Adapter is not working with Stock Android

Sorry for resurrecting this old thread.

I have an adapter with the same chip, but I can`t get it to work. Well, it works - but only 100 Mbit. (Last version from kszaq).

Here is what I get:

The Adapter is indeed a r8153 - pluged it in my desktop and it works fine. 1000 Mbit. I have only a Windows 10 machine to test here atm, but driver says its a realtek 8153

Any ideas?

@Tim_Taylor Thank you.

could you run

ethtool -i usbnet0

please?

I still have no idea...

Not necessarily.

My RT8153 adapter shows up as eth1 and my AX88179 adapter shows up as usbnet0.

puked:

I heard a fake rt8153 adapter which was 100 mpbs only probably contained 8152 chip

puked · March 23, 2018 at 10:10 AM

as I said - I tested it on my windows machine and it is indeed gigabit - does not just say so, but gives me gigabit speeds. Copied a file over smb and got ~40 MB/S. ID hints to 8153, too

edit: Works on a raspi (raspbian) ootb - gigabit here, too.

SPMC is currently only available as a Jarvis build.

There were a couple of scattered Krypton attempts by SPMC, but it is likely to remain that way for some time to come, as the SPMC developer Koying has recently moved over to the MrMC team.

Also, HDR is still a work-in-progress in Kodi Leia.

hm

your adapter uses the r8152.ko module, too. as expected.

lsusb gives me:

You are using an usb-hub, try to connect direct to onboard usb port

puked · March 23, 2018 at 1:16 PM

I would =)

but - the lan port is part of that hub

seems like I need another adapter.
