By "and then stop" do you mean the playback or seeking in the movie?

Does this not happen with other renderers available in MPC-HC?
Does this happen on all of your files?
Is your file ripped directly (from TV broadcast, etc.) or is it properly into mkv or other container that supports keyframes properly? Try muxing you file with mkvmerge GUI (free tool) to make sure it's not your file(s) being broken.
Do you have any of the "use separate device for ..." options enabled? If yes, try disabling them.
What does the debug OSD (CTRL+J) say after seeking?
What decoders and other filters are you using? What Windows version are you on?
1. 5-10 consecutive jumps.
2. Stop seeking.
3. Haven't tried other renderers.
4. I think it only happens with high-resolution (720p+) H264 files.
5. Files are properly muxed with MKVmerge, quite a few of them by myself.
6. I had it enabled on my desktop, but not on my laptop.
7. Strangely enough, the one time I remember that the issue didn't go away no matter what, I checked the statistics and no dropped frames were being reported whatsoever.
8. LAV as splitter, ffdshow as both video and audio decoder. Windows 7 x64.

Sorry that I can't give much useful info, the issue isn't always reproducible.

Decent fixed function units (as seen on the GTX 960 or Broadwell) should be much faster than CPU for decoding, especially with HEVC.

Pretty much this. However there are some content out there now that aren't possible to decode fast enough using just software decoder on a average CPU(typical quad core). (Hevc 4k and those samples).
Hardware decode also typically give off less heat, hence less noise.

So for typical 1080p content, it is up to user liking IMO. I personally stick with software.

If the CPU is not fast enough for your content, then there's no other option but to enable some kind of hardware acceleration/decode.

Gotcha guys.. Thx for the infos.

I need dxva on my pathetic 2520m laptop. The cooler is so crummy that using software lav + gpu catmull scale will push 80C, whereas dxva lav+madvr-dxva scaling only pushes 60C

That's 20C difference.. and it's only a 1366x768 output..

Anyone else try the AMD 15.3 beta driver yet?
A quick check with 720p material upscaled to 1080p (on an R9 270, using NNEDI) shows a performance on par with the 13.12 driver
Will test more later...

defiantly not a interop fix.
maybe be abit faster maybe not.
using a haswell CPU and a r9 270

I tested the 15.3 Beta... and yet again on my rig, with settings pushed to the max, madVR performance dropped. All I do to recover the performance is roll-back the driver to 13.251 (I don't do a catalyst re-install)

Do try it. I think it might be a problem with the decoder, since no one else seems to be having this issue. If it's not really linked to madVR, we should move to a separate thread.

Do you have hardware decoding enabled (DVXA/QuickSync/CUDA)? Try disabling it.
Also check GPU memory usage (with GPU-Z (freeware) or similar) and try lowering the queues' sizes.

I would strongly advise you to switch to LAVFilters completely to avoid compatibility issues and just use a decoder that is actively developed.

Agreed, but that doesn't help the OP until he does a future upgrade.

Madshi, any ideas what's causing madVR to crash when using latest MPC-BE along with XYsubFilter?

Any update on the black screen issue on Nvidia Optimus 800 series laptops?

Few quick questions please.

Just tried error diffusion - option 2 (latest madvr - Zoomplayer - Lav). I can see the small description next to it saying its different opt 1, but was just wondering is opt 2 a better option. I notice its slightly more expensive to run.


2nd. I tried option 2 because all of a sudden option 1 was showing thin vertical black lines on the screen. Took me ages to narrow down what was causing it. First I thought zoomplayer, so reset and loaded settings backup, and then moved onto madvr doing the same. I then started to go thru all the options one by one in madvr settings window and got to changing from error diffusion opt1 (my default) to opt 2 made the lines go away once I pressed apply. Back to opt1 and apply and the lines come back. No idea why, it just started today. Anyone have any thoughts on this?

screengrab: http://i57.tinypic.com/2a7tpbb.jpg

NV driver: 347.88 WHQL > HDMI > 50inch plasma TV



3rd question. The crash I mentioned above didn't manage to send via the web. I've only ever seen it send maybe twice in all the time I've been using madvr (which is years), and its tried many times. Zoom player Max v10 (my player) has access to the web, so do I need to allow some madvr exe access also via my PC firewall (Eset Smart Security 8). I hadn't had a crash for ages so just forgot to follow up why madvr crash reporter never managed to connect.

Thanks in advance guys.

Do you know if it's a problem with the player, madVR, the intel/nvidia drivers or all the above? I wish I could understand the root of the black screen and freeze problem on optimus laptops with nvidia selected.

know issue. since driver version 347.25
http://bugs.madshi.net/view.php?id=250

i don't think mode 2 is better it's just different. just choice what looks better to you, if you don't see a difference don't use it.

it's pretty clear this is an nvidia/intel driver issue.

Didn't MPDN have similar problems with Optimus that were later fixed? I do not follow that topic closely, but I vaguely remember a black screen issue with too large queue size. I am not sure if that was Optimus specific. But you could test with all queues at minimum size in madVR.

that's what i know:
http://forum.doom9.org/showthread.ph...optimus&page=3

maybe MPDN has a better chance in fixing this it is a hole new problem while mpc-hc and player like that are normal playback software that is usually set to low powerstate/iGPU to spare power.

people can try min queue size but some feature may totally fail with that.

Ah I see a known bug, thank you for pointing that out. Yes I was on a driver some 4 months old before updating yesterday. I even updated again today to 347.90 in the hope it would fix it, but alas it didn't.
