CroqueMr did you figure out why the display outputs to my laptop screen rather than tv ? Were the logs I gave helpful? Do u need more logs? Any update ?
Thanks.
I had the same issue, but I don't think it's LE's fault. Have Ai walk you through the commands you need via SSH to disable the internal display and only output to HDMI.
I also get this with every video I play. If I stream from an add on that series splash page will stay on the screen for ~3 seconds in the beginning.
Which build and version are you on right now? It helps to know what you're comparing against.
Hard to say without trying, since nobody has run Hades on a 3500U yet, but its graphics (Vega 8 ) are supported for native Dolby Vision. Your case is what the latest version worked on: with the OSD, the seek bar or subtitles over a Dolby Vision film, each frame is now redrawn only where they are. On the integrated graphics of a Ryzen 9 7950X3D, which has just 2 compute units, a profile 7 FEL film with the seek bar and the info panel open keeps all its frames, and a user saw the same on a Radeon RX 7600. The 3500U has more compute units but usually much slower memory, so I can't promise the same. If you try it, the Dolby Vision page of the player info shows the GPU time of each frame and how much headroom is left.
Just switched to your RC3 build. Same issue. Would I be better off swapping this out for an N150? Or do you think this is fixable for the 3500u?
hadesdevls do you think your build would run better with my 3500u? I still get a lot of frame drops opening the OSD on a profile 7 movie.
I was able to eek out some better performance on the 3500u box I have but still get huge spikes bringing up the OSD. Anyone else still seeing that issue?
With FEL, no issues?
Thanks.
Also wondering, because my 3500u definitely has FEL issues.
Sorry if it's a stupid question but any chance someone has tested DV and or 3d with a 3500U? Very cost effective at the moment.
You can see my other posts where I have. Better performance with beta 3 but still getting frame drops, especially without fast processing enabled.
Thank you, I will check if we can have a better approch for this kind of CPU can you send me the kodi.log file please.
I see exactly why it does that the cause is an optimization I made in the R0.3 build, I will fix that.
It's attached to my original post. Are you not seeing that?
Thanks for the improvements in Beta3! I've tested the same Profile 7 FEL content with fast rendering disabled and enabled.
There does seem to be a noticeable improvement with fast rendering enabled:
The tests weren't identical in duration or playback position, but with fast rendering enabled, the skipped-frame counter increased much more slowly after the initial playback period, with several intervals showing almost no additional skips.
I'm still seeing repeated OutputPicture - timeout waiting for buffer messages in both sessions.
I also noticed the following message:
CB1 FEL upscaling: VAAPI unavailable, using full shader FEL reconstruction
It looks like the Vega 8 isn't benefiting from the new VA-API FEL upscaling optimization.
Display MoreNot normal and never saw this issue, what CPU do you have?
Thanks a lot
I am finalizing to integrate the last improvement lever from tour last build, and I convert your optimization for AMD also. I will check the new oprimisation gain.
Edit : Last improvement integrated, it's your chroma filter, this will be optional because it's reduce a little bit the fidelity (around 0,9%) of chrominance. Looking extremely closely at a shot where the discrepancy is at its greatest, you can perceive a tiny difference in the outline of the light halos. It's almost imperceptible and, above all, only visible in very few shots, but since it still has a tiny visible impact, it will be an optional optimization.
Now I work to implement Onecinema's build and I will push the beta3
Thank you for the feedback, beta3 will have some new performance gain. It will help your CPU handle FEL.
Opening ny GUI will increase framedrop. If you do not open anything and leave the film in full screen do you have frame drop?
I know Kodi only tracks one type of frame drop, so the counter isn’t perfect. But I don’t think expanding it to count every dropped frame would be particularly useful, it would also include drops caused by the GUI, which don’t occur during fullscreen playback with the interface hidden.
Thanks for the response! Looking forward to trying Beta3.
Yes, the skipped-frame counter continues to increase even during uninterrupted fullscreen playback with the GUI hidden. However, the counter doesn't seem to correlate with any noticeable stuttering on screen, so I'm not sure how accurately it reflects actual playback performance.
Do you think the buffer timeouts could be related to the FEL processing overhead, or potentially an AMD-specific frame presentation issue?
I'll report back once I've had a chance to test Beta3.
Ryzen 5 3500U / Vega 8 – Dolby Vision FEL frame skipping on R1.0.0 Beta2
I'm testing R1.0.0 Beta2 on a Ryzen 5 3500U with Radeon Vega 8 graphics, connected via HDMI through a Denon AVR.
Dolby Vision Profile 7 FEL playback works, including enhancement-layer processing, but I'm seeing skipped frames accumulate during playback.
System:
What I'm observing:
The logs suggest that frames are being delayed somewhere in the decoding/rendering/presentation pipeline, although I'm not sure whether this is a GPU performance limitation or an AMD driver synchronization issue.
Any hardware you guys need tested? Was looking at getting a mini pc with a Ryzen 3500u
