[TESTING] Linux 4.9 kernel and improved video stack for Vero 4K / 4K +

Ah, now the reason is clean. Why the algorithm isn’t trying to set the most closer higher resolution if it can’t see the exact one? It because of that the higher resolution supports lower frame rate?

Video orientation issue with H265 (hevc) video made with samsung galaxy S8.
Video is played whatever it is 1080p;,59,940 FPS; H265 or 4K ;30FPS; H265 but it is played upside down.
Nvidia shield with latest kodi 18.7 plays it normally

Here is file media info:
4K 30FPS

or
1080p 59,940FPS

And here is logs:

If needed I can upload some video.

Edit: For H264 video manually I can change orientation. Like example if video is made like example in portrait mode, then I change manually orientation to 90 and it shows video in portrait mode (vertical I mean)

But for H265 videos manually orientation not work. I can put manually like example 180 or 90, but it is not changing. Changes just 270, but if video is made normal(not in portrait mode ) then it plays vertical.

If the video is actually 2160p/50Hz and the display cannot handle 2160p or higher at any refresh rate above 30Hz then what are you expecting the player to do? There is no “correct” mode available, here.

How than in 4096/24 mode the same video is played without any problem?

BTW, how to make a screenshot in OSMC?

It probably isn’t, it’s probably played as 2160p/24.

Because if you set the GUI to 4k/24, that’s the fall-back.

If your only seeing 24 out of every 50 frames then I think many would consider that a problem. Your TV is not capable of display this particular video without compromise. This is a limitation of your TV, not the player. As such you can either choose to have a higher resolution with dropped frames or bring the UI back down to 1080p and allow the Vero to downscale it but play it at a correct frame rate.

Your tv seems to support only the following:

HDMI 1, 2, 3, 4 (support 4K resolution)
Video (2D): 4096 × 2160p (50, 60 Hz), 4096 × 2160p (24 Hz), 3840 × 2160p (50, 60 Hz), 3840 × 2160p (24, 25, 30 Hz), 1080p (30, 50, 60 Hz), 1080/ 24p, 1080i (50, 60 Hz), 720p (30, 50, 60 Hz), 720/ 24p, 576p, 576i, 480p, 480i, PC Formats
*YCbCr 4:2:0 / 8 bit
Video (3D):
Frame Packing: 1080p (30 Hz), 1080/24p,
1080i (50, 60 Hz), 720p (30, 50, 60 Hz), 720/24p Side-by-Side: 1080p (50, 60 Hz), 1080/24p, 1080i (50, 60 Hz), 720p (50, 60 Hz)
Over-Under: 1080p (30, 50, 60 Hz), 1080/24p, 1080i (50, 60 Hz), 720p (50, 60 Hz)
Audio: 5.1 channel linear PCM: 32, 44.1 and 48 kHz, 16, 20 and 24 bits, Dolby Digital
ARC (Audio Return Channel) (HDMI IN 1 only)

Now I understand why in 4096 mode I can see the movie with some delays. Thank you all for clarification of this issue.

Can you share a part of your video, I would check it on my environment?

I’ve found two ways.

  1. By keyboard Ctrl-S. [Need to be enabled Settings > Services > Remote control].
  2. By ssh command kodi-send --action=TakeScreenshot.

And, of course do not forget to set System->Settings-Debug->Screenshot Folder.

@kwk_kwk Two questions: 1) Is this 4K/50Hz video you’re trying to play HDR, or is it SDR 8-bit? 2) Have you checked the “Force 422 subsampling” box?

EDIT: The reason I ask is, your TV can accept 2160p/50Hz signal, but only in 8-bit, and only with 420 subsampling. So, if you have that box checked, you need to uncheck it; and if the Video is HDR, it won’t play, or at least not without converting to 8-bit SDR on the fly.

is it a known fault where you try to play a video and it stars for 1-2 secs then stops, reboot still does same sometimes 2-3 attempts then odd time 10+ tries before it plays, yet other videos play fine, but all ones from same tv shows does same

We’ve fixed that so should be solved in the next build.

I’m still working on your USB reset issue to solve problems with the tuners on a warm boot.

Cheers

cheers, whens next build due? or is there a way to patch the fix for now

Unfortunately I don’t have an ETA just yet. A few things to get done first.

If this is the MTU issue with Kodi SMB paths then you can either make you devices use SMBv3 or otherwise switch to system paths which are not affected. If you had updated Kodi to the latest update and not downgraded then you could alternatively just enable settings>services>SMB client>mitigate MTU issues with SMBv2

cheers, that seems to work, NAS drive is SMB2

Hello guys,

After upgrade to improved video stack music playback is limited to 96/24, before I was able to get 192/24 but it’s not possible anymore. Is it same for you?
