Hey!

Wrestling with my old laptop that I use as a HTPC (AMD Phenom II N930 2Ghz and AMD 5650m+4250 gpu), and after reinstalling windows 7 64-bit and updating mpc-hc and madVR (64-bit) to their latest nightly, I can barely get bilinear to work. Is there any change about performance in older rigs as mine from 89.x to latest? Or am I missing some requirement I am supposed to install (vcredist etc)? GPU-z shows that the clocks go up for 3D (550/800) and that the utilization is low (0%-20%), yet still I get "dips" in the queues occasionally and starting+switching to fullscreen results in around 20-30 dropped frames, no matter if exclusive or not. I am "forced" to use gpu-drivers from 2012 (Catalyst 12.4 to be exact) as I have a legacy GPU on my motherboard and AMD doesn't support them.

So, is there any queue-tweaks or rendering tweaks I should take into consideration? I was happily running Mitchell-Netravali for luma and Bicubic 75+AR on chroma (as well as debanding) before on my laptop, though it was pretty loud occasionally.

Another slightly off-topic question, does clock-speed affect temperatures if voltages stay the same?

Does that mean the MadVr decoding isn't fast enough? Or that my CPU isn't fast enough? Just trying to figure out if a CPU/motherboard upgrade will help or not.

I'm getting smooth playback for 10 min or so and then it gets very choppy until I pause or stop the playback.

Thanks!

that should be a CPU issue.
but i have no clue what type of content you are playing there.

you are saying it starts after 10 min that could mean the CPU is thermal throttling or something unlikely like the file get's way harder to decode. could be power saving mode too or something like that.

what so ever the frames are not delivered fast enough to madVR or it least that's what i see on the screen.

thanks @huhn. I see this behavior with most HEVC content, especially with bitrates higher than 1800kbps or so. In most cases, I will play 1080p content on a 1080p display, so no scaling beyond the basic Chroma.

Some tools (e.g. Nvidia Inspector) can read out video processor's utilization, how much is it during video playback? And how much GPU and CPU usage?

what your is video card, CPU and decoder settings?

Your GTX 960 is not decoding HEVC. This sounds like a problem with DXVA2 (copy-back) and LAV Video.

Didn't you say MPC-HC was fine and Emby was not? Is Emby or your settings in Emby the problem?

My LAV Filters are set up to with HEVC checked and DXVA2 (copy-back). When I play a HEVC file with MPC and check the LAV Video Settings during playback, I will see the HEVC box checked. However, when I play back the same file in Emby using the MadVR rendering, the HEVC box is NOT checked.

Checking the MadVR on-screen stats, I'll see that the average rendering time is around 11-12 ms, so plenty low. But the max render will jump to 50+ and sometimes 100+ ms. Very strange. Even when the average stays consistent around 12 ms, I still see dropped frames every few seconds.
Emby keeps it's own copies of madVr and LavFilters in the Users userdata? folder. If you have LAV installed separately, Emby ignores it. You'll need to edit the config file in the Emby folder.

Just wondering...what is a low (under 1,000 kbps?), medium (over 1,000 kbps?), and high bitrate (over, 2,000 kbps?) for x265?

The menus in Emby Theater allow the user to enable hardware acceleration. There is no need to go into the folders. At least, as far as I know.

Thanks for the Nvidia Inspector suggestion. I downloaded it and I think it's helped me narrow down the problem. More below...

It looks like the primary problem is with Emby Theater not allowing HEVC hardware decoding in the LAV Video settings. I downloaded Nvidia Inspector and noticed that VPU Load is 0% during HEVC playback in Emby. If I play the same file in MPC-HT, the VPU load stays steady at 8%. The GPU and MCU loads both fluctuate between 10-30% in both Emby and MPC.

It seems that Emby Theater is using a separate version of LAV and I can't seem to locate the config file so I'm not sure how to enable HEVC hardware decoding. I'm hoping to get an answer in the Emby forums.

Great question. lol. I've generally seen most 1080p x265 encodes to be around 1200-1600 kbps, so I guess that's medium? I would prefer closer to 3000 kbps, if I can get smooth playback.

I have a GTX 960 that I purchased specifically for x265 playback. My CPU is not too good though - AMD A6-6400k.

It seems that I get some dropped frames even playing x265 files in MPC, even though the GPU and MCU (is the CPU?) loads never go much higher than 30% or so. Is that to be expected?

My decoder settings for 1080p 24fps playback (1080p plasma TV) are pretty conservative. I have debanding @ edium, BiCubic Luma, upscaling, full screen exclusive, ordered dithering.


Thanks again for all the help guys. I really appreciate it!

The latest Emby Theater does not expose many settings. Hardware acceleration is one of the few, but not H265 or many of the others. For madVr, Emby exposes smooth playback only - any other options need to be configured in the XML settings. And they are separate from any other installation.

Do you happen to know the folder location of the XML file?

Yes and it works, there are some things which are known that the driver is causing it but besides this, it works. Give it time it's new.

Please stay on the topic, we already have 1000 pages with off-topic because most questions are how to setup madvr or how to configure your device.

I think we not need to talk about driver related issue, since it may get changed in the next version. It would be more important if it affects everyone and not only a specific range of people. The 1080 have thermal issue (due reference design) and gamut problems due driver, I not go into detail as long we not get another driver to compare. As said it takes time and 368.25 is the only whql currently for the 1080. There are under some environments also other problems with VXAO, TDR and HBAo+ but overall I don't think it affect something you can directly see within madvr.

I posted about my RAM reaching 95% after ihr playback 3 pages back.
Please help me figure out the problem.
Since nothing is getting crashed,i'm unable to get crash log & this occurs only after long time of playback (1hr).
So reproducing same effect is a timetaking process.
Problem i'm getting is it's way beyond what RAM usase should be (25% at initial,then 23-35% seems okay value) & i'm unable to jump forward or backward properly.

Can anyone say what can i do to generate debug info or any log that can be useful to figure out problem????

You should really attempt some troubleshooting before posting... How do you even know this is related to madVR? Come back with more information after you've put in some effort to narrow it down. And also you should know about the debug batch file in the madVR directory....
