Nope - same result - latest log:

Yeah, sorry, you were too fast... I uploaded the wrong build. Please try again the link in my previous edited post.

Excellent - Crash is fixed!

Did some quick testing, as follows:
- Play 3D Video = It is in 3D!
- Stop and Play same file again = SBS D9 mode
- Stop and Play a 2D Video = Fine
- Stop and Play the 3D File = It is in 3D but playback is not advancing. I need to press Pause then Play and it then plays fine

Do you want some Debug logs of this?

[jmone]

I should say it is apparent that playback starts while my TV/GPU is switching mode several times (and I see a "no hdmi connection msg" in the middle of all this display switching)

Yes, debug logs would be helpful. If possible it would be great if the logs would only contain the failures, not the success. Meaning, if you could stop MC, then delete the log, then start MC and reproduce SBS D9 mode. Not sure if it's possible to do that, though. Then stop MC again without doing anything else. Same for the 3D pause/playback problem. But there please let playback stay paused for 20 seconds, then press pause + play, then close MC. Thanks!

Yeah, unfortunately madVR cannot know how long the display needs to resync. But I suppose I could add an option to delay playback start when switching into 3D mode. Would that be helpful? But usually at the start of a movie, there's some stupid movie studio intro, anyway, so I'm not sure whether it's really necessary...

Edit: You'll need a new debug build for this, with the crash bug fixed. Will upload that in 2 hours or so...

[jmone]

Yes it is possible to grab the debug logs in this method. It's 9pm here so once I have the new build I'll generate them tomorrow and upload a pack just showing the issues. Thanks for the quick to and fro on this and fixing the crash (makes it easier to find the rest)!

edit - also I don't care about losing the first few seconds when switching modes, more that I thought the loss of HDMI signal during the switching may cause some of the issues.

You could try to reset the reclock timing database, that might help. In any case, this sounds like a reclock problem to me.

I tried to disable reclock, still get some frame drop like OSD told me every 4min+.

Another problem is if I play more than 1 hour, I will get massive frame drop in FSE. I have to pause play and switch to windowed mode wait few seconds then the frame drop gone.

disable frame packing playback like SBS is the most reliable way in my system.

Edit: new build:
http://madshi.net/madVRjmone2.rar

good news mashi! With this new build, my crahes when starting 3D or 2D files after 3D is activated in OS control panel are fixed too!


Bad news are: osd says "D3D11 windowed 3D" but video is shown in 2D. And rendertimes are higher as normal 80ms instead of 38ms.

Any idea? I'm using a LG 4K passive tv. Could that be a problem?

Edit:
OSD says, movie resolution is 1080p and scaling to 2160p... shouldn't it be shown in 1080p 3D mode without scaling?


Edit 2: My native desktop resolution is 38040x2160. It can manually change to 3D mode in nvidia control panel to 1080p(3D) mode. The my desktop is shown in 3D with 1080p resolution. If I start a 3D MVC Mkv now, madvr crashes and my tv is telling me that there is no 3D signal and changing back to 2D mode. When desktop is switching back to 3D mode, tv gets a message that there is 3D mode active again.

Then you need to create a custom resolution to get your refresh rate tuned.

Not sure why that occurs. Do you have any 3rd party application running which might access the GPU?

Double render times are expected if madVR tries to render 3D.

That is with the test build? That sounds strange. The test build should manually switch your GPU to 1080p23 mode if you try to play 3D content. Why is your GPU mode still 2160p? Do you have display mode switching active somewhere outside of madVR? E.g. do you have MPC-HC/BE's display mode switcher active? Or some other media player's display mode switcher?

Bug report?

nope, I use madvr to switch display modes... do I have to write a 1080p23 (3D) mode under the display modes tab?

Bug report?

I'll try to get one, last time I was told that mpc-hc has crashed. Ill try and be back in some mins...

[Sunset1982]

@madshi:

found the bug... the bug was me!!!

forgot to write down 1080p23 mode under the display modes tab!!
now 3D is working!!


And the crash by selecting 1080p3D mode was, because I was manually switching to 1080p24 and not 1080p23 mode. If I select 1080p23, it works!

That's still a bit surprising, though, because the test build was supposed to automatically switch to 1080p23 for 3D content, regardless of which mode you entered in the display modes tab.

For me it won't switch, I have to type in 1080p23 and even then it seems like it switches to 2D first before activating frame-packed mode after I tab out and in again, it's rather weird.

I watched Full-SBS yesterday with no issues, the only problem is the amount of GPU power consumed, my 970 could only handle Jinc3 Upscaling + Chroma sampling and ordered dithering on 2160p Full-SBS mode.

Frame-packed mode seems to drain like 4x less power, and since upscaling 3D content to 4k seems near impossible frame-packed is the way, the only issue is that it's very buggy at the moment, my custom profile still has bugs when switching from 2D to frame-packed.

I'll try drop a debug If i got time.

Is the with official v0.90.2 or with today's test build?

90.2, didn't see there was a test version out :s

[Sunset1982]

same with me (used latest testbuild). 3D is working but only if I put 1080p23 in the display mode tab. But I think it'll choose it even for 2D and will not upscale other movies, right?

Can I have two debug logs, please? One with 1080p23 in the display mode tab, and one without. So that I can compare why there's a difference. Thanks.

Please create the logs with this new test build (contains both release and debug build, but only 32bit):

ok, but how to do this?

[Sunset1982]

ok, created the two logfiles. hopefully if done it right.

Ah, I see, thanks. The cause of the problem is that the LAV Video Decoder doesn't inform madVR yet about whether the movie is 3D or not, at the time when LAV and madVR are connected. This is already planned, though. The next LAV build will probably already do that. So by then this problem should automatically be fixed. You will then be able to remove the 1080p23 from the settings dialog, but madVR will still automatically switch to 1080p23 for 3D movies - but to your 4K resolutions for 2D movies.
