I have one 1080i blu-ray concert that is not playable anymore since madvr does the deinterlacing : Dire Straits, live alchemy. It worked perfectly with 17.0.147.
I have loads of repeated frames as if the video was going forwards/backwards
-
I'll report here too my hardware deinterlacing problems, especially with 1080i content.
-
Would it be possible for someone to upload a sample somewhere where we (JRiver, madshi) can look at the problem? Thanks.
-
I'll try to cut the first minute or so ...
-
Where to can I uypload one avi file with about 100 MB? Itīs the smaller one I have.
I can do it to Dropbox or Skydrive, but I need an email to make you the invitation to share the folder.

Here's (http://www.mediafire.com/?i5s9bg9xay00dnj) a clip. It deinterlaces properly on an ATI system, but not on Nvidia.
@JoaoMOS: try Mediafire
-
We tried the clip here and it played fine on upper end Nvidia and ATI cards. Unless the problem is something subtle that we're not noticing.
-
I'm using a lower-end NVIDIA card (GT240), never had such issues with it in previous MC versions. In an ATI 5670 motion is silk-smooth, in the Nvidia it seems like a lesser deinterlacing method is performed - motion is blurry, especially in fast moving scenes - maybe that particular clip isn't too revealing, although the difference is quite noticeable.
-
That's interesting. We made the change to let madVR handle de-interlacing rather than the LAV decoder because the experts said that would be more efficient. But from what you describe, it seems to be less efficient. Any thoughts from the de-interlacing gurus would be appreciated here.

This thread really doesn't have many useful informations.
1) Are you using RO or ROHQ? (or even custom)
1b) If ROHQ, does RO show the same behaviour?
2) Do you have Hardware accelerated video decoding active?
2b) Does it show the same behaviour if you turn it off?
2c) How do older builds behave if you use it with/without HW decoding?
3) If ROHQ, did you fiddle with the madVR settings at all, possibly the deinterlacing settings?
As a general rule, the GPU can only perform certain types of deinterlacing, and the same deinterlacing is usually performed no matter who does it.
I do however know about some problems with rather old NVIDIA systems and combining CUVID decoding with certain renderer functions, but i don't think it only showed as worse deinterlacing, it usually had rather severe problems then.
When i was developing the CUVID decoder for NVIDIA cards, i specifically compared it to EVR's deinterlacing, because thats usually the best the GPU can do.

Yes, everyone should post the relevant details about their video setup in Media Center.
madshi noted that if they had been using single rate LAV deinterlacing (using custom setup), now madVR (and maybe EVR??) uses double rate deinterlacing which means more work is being done. Might this cause lower end cards to display more poorly?

1) RO=plays ok, ROHQ=not ok (but always did before with HW accel=ON)
2) Yes. RO with HW acc. ON/OFF=ok, ROHQ with HW acc.on/off=not ok [2b=yes, 2c=can't test now, older builds always ok with ROHQ & HW=on]
3) Might have, but only after noticing this problem. I've reset the settings and tested again.

Never had issues with LAV's 50p/60p adaptive HQ mode in previous versions, or MPC-HC/DVBViewer Pro.

Hello John T
I have just uploaded one of my avi files /the smakker one) to mediafire.
The link is as follows
http://www.mediafire.com/?rn4zlgyzvds289d
All avi files fail in Media Center. But they run in Windows Medis Player.
And before the update to, I think 147, it worked fine in Media Center.

I can play this file OK. Are you using Red October Standard, HQ, or custom? HW Accel. On or Off?
-
JoaoMOS' clip plays ok here with ROHQ/hw.acc.=ON.
-
here's a sample :
http://netload.in/datei2tcGzXCzeT/1_2_video-001.mkv.htm
It becomes problematic when aspect ratio is set to "crop black bars 2.35".
I use ROHQ with HW Accel ON. It works great with 17.0.147, not with 17.0.155
-
I was having problems with 1080i video on Nvidia. Nvidia 301.42 which Nvidia pushed down today resolved it. I would loose video sync with 1080i content, 480i played fine.

So its just fine if you don't do cropping?
Anyone else that experience the problem using cropping?

What do you mean by that?
Accel on/off. I think is ON, but for many many time that i Donīt select such thing.
I have a Nvidia GTX 285 and was using the 296.10 driver. Today I updated to 301.42 driver. The problem persists
My CPU is a i7 920, 24 GB RAM, 120 GB SSD for system and software, 1 TB + 500 GB HD.
I repeat. Everything was OK and nothing changed in my sistem except Media Center update.
The Clip I sent you runs in Windows Media Center, but all my video files are prepared to open with Media Center as prefered program.
All the other formats run perfectly. Only AVI doesn't run. No one of my AVI files runs. And I have a lot.
I ask you please to be more concise about what I must do, and please notify me by email. I have that option selected but I'm never notified.
Best regards
JoaoMOS

what is even weirder is that it's fine only if I don't do cropping and if I don't keep the bdmv structure but use and mkv instead (I found out that making you the sample)
-
If the problem only occurs with RO HQ, Matt or John should probably ask madshi to look into it.
In the meantime, they could possibly re-enable CUVID deinterlacing for RO HQ (the performance advantage of using renderer deinterlacing can be ignored for HQ as its designed to require more power)
-
Hello again John T
I went to options menu and IO saw what you meant.
I was runing in Red Octiober standard and no Hw Acc.
I changed to Red October HQ and Hw Acc ON.
But the problem still persists.
In an AVI file I receive the message: "Something went wrong with playback."
I forgot to tell you that my OS is Windows 7 64.
Best Regards

@JoaoMOS: Your problem seems completely unrelated to Deinterlacing, you should open a new thread if anything so your posts don't get burried here, because they are off-topic for this thread.
This thread specifically is about deinterlacing in RO HQ in recent builds.

I've been sent here from MC 17 155 by John T.
Tell me please were can I post my problem.
For me any place is good since my problem is solved.
You know what the problem is, so tell me please where I must go.
Sorry if I disturbed you
