Hi All,
my vero 4k arrived today and I have configured it in place of my old Pi3. It’s great to be able to play 4K HDR films and finally get HD Audio but I’m somewhat disappointed with the speed in the gui. I’m using confluence skin as always but things definitely seem sluggish compared to the slightly overclocked Pi3. I assume there’s a setting somewhere I have wrong or can apply, but where and what?
Can anyone help me please?
Thanks

I noticed this when i got it as well.
I am running a test build at the moment, and it runs super smooth, I’m on the Estuary skin though.
So i’m sure you will notice a difference after the next update.
Confluence or Aeon (which I’m running) are smooth as hell 
I configured the UI to be in 1080p, default is half of that.
Thing is, on the first start, things are a little slower as all the updates, scans etc. run. when all that is done, it should be smooth.
Note: Mine is connected to Fast-Ethernet, MySQL DB running on the NAS, and all Medias served via NFS.
I noticed the same using Xonfluence when I got it - in the meantime it’s super smooth.
There are GUI performance improvements that will come in tomorrow’s update.
There was an issue where the GPU core scaling was too aggressive which could cause some minor UI stuttering. Let me know if the issue persists after tomorrow
Cheers
Sam
That’s great thanks Sam. Are we still on for the update today do you know?
Thanks

No update today. I am waiting for Kodi v17.1 to land instead. It’s not far off (a day or so)
Oh well thanks anyway. I’ll keep checking back daily then
You can get the improvements now via the staging repository, but this isn’t the final update I’ll put out shortly.
/etc/apt/sources.list
deb http://apt.osmc.tv jessie-devel main
sudo apt-get update && sudo apt-get dist-upgrade && reboot
I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.
Thanks Sam. I’ll try it later
Hi Sam,
just tried it and it’s sorted the issues. All my test files are streaming from my NAS without stuttering and things seem speedier. Thanks for the great support.
One thing I’ve noticed which I wonder whether anyone has reported is to do with HDR playback. I have seen some shimmering on large areas of similar colour. For example in one of the films I have there’s a bit where the main character is looking across at a nurse. The shot pans around and to the right of her is a white wall. On my LG B6 tv this is a bit shimmery.If i pause the film it continues to shimmer. Very odd. Since it’s a backup rip I can put it on a memory stick and when I play that on the tv directly (The tv does 4k hdr playback from memory stick) I get no shimmer. Has this been reported I wonder? It’s not a major issue and certainly doesn’t appear to happen on non HDR films - at least I haven’t seen it 
Thanks again for the quick replies to my earlier issues. I’m certainly glad I bought the Vero. A marked step up from the Pi3.

Hi Mat,
Glad to hear things are much improved for you. You might want to go back to the normal release repository unless you like living a little dangerously.
A photo would help if you can produce one. It would also be interesting to know if running:
echo 0 | sudo tee /sys/module/am_vecm/parameters/hdr_mode
helps with this problem.
Hi Sam,
I’ve moved back to the normal repository thanks - I like to live dangerously but I’d rather have a stable platform first
I’m not sure a photo would help with the shimmering since it’s a flickering image. It does still flicker when paused though so I’ll see if I can capture some video perhaps.
If I try the suggested command will it make any permanent changes or is it temporary? If my unix skills are remembered correctly then this will basically set hdr_mode to 0. What is it currently and what are the different options? Is it documented somewhere? Sorry to bombard you with questions but this is all really interesting
While we’re “chatting”, I have one more question. I tried the “HD Club Showreel (2014)” test file from here (http://www.4ktv.de/testvideos/) last night. It’s a 100meg bitrate and is x264 encoded. The playback struggled with lots of breakup and sound loss followed by finally appearing to hang. I have played similar high bit rate x265 demos without issue so I wondered if the x264 decoder has an issue perhaps? I have a couple of large (100Gb+) h264 encoded 4k films and they struggle too.
Thanks again for the help and keep up the good work!

Did you try copying the file to local storage to rule out a network issue?
The HDR option is temporary: a reboot would then revert the changes. I’d advise against delving in to these parameters too much at this time
Sam
I will try it tonight and let you know
Thanks

Hi Sam,
having done this yesterday [quote=“sam_nazarko, post:9, topic:35350, full:true”]
You can get the improvements now via the staging repository, but this isn’t the final update I’ll put out shortly.
Login via the command line
Edit the file /etc/apt/sources.list
Add the following line: deb http://apt.osmc.tv jessie-devel main
Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
Your system should have have received the update.
I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

when I now scan for updates it tells me there aren’t any. Is that correct? I removed the line and returned to the normal update channel and rebooted
Thanks
-Mat
I should think so.
HI Sam,
copying the HD Club Showreel onto local storage didn’t make any difference I’m afraid. Still breakup followed by complete stop.
Thanks
-Mat
So the build is the same then? Sam’s email seemed to indicate it was a pre-release and more would come in the ‘official’ build today.
Thanks

Is there seriously any “available” media in 100mb bitrate?? I highly doubt it. This is a test file… There are full desktop systems that cannot keep up with that. I think you are expecting a use case to be supported that doesn’t exist.
