New Unofficial DSCALER5 with 3:2 Pulldown for 1080i - Page 4

The orginal version I had split decoding and processing to 2 threads but I found this increased stutter too much, I'll revisit this at some point.

I'm not surprised about the 1080i taking all the CPU, maybe one day I can optimize some of the code a bit ...

Hi,John
why do the dscaler mpeg decoder 5006&5007 can't remember settings i made,i have to go to properties tag and do some setting again everytime i open my software player.
thanks

kzeuh, You are the MAN!

I have so many 1080i .ts files that were badly flagged and had interlace artifacts ALL over the place.

All 3 harry potter's
Spider-man 2 (Spidey 1 has proper flags)
Usual Suspects
contact
truman show
matrix revolutions
etc, etc

I was getting discouraged because i had all these movies that looked like crap when using ffdshow to de-interlace. They look absolutely stunning now!!! WOOHOO!!!!!

I have found one movie that will not allow 3:2 pulldown to be done on itself. Ocean's Eleven from the station...drum roll... ABC. Ugh, whats up with abc, do they know what they are doing over there? I have tried all of the Inverse Telecine options and there is interlacing all over.

I have noticed that if I set it to do IVTC only when it is detected, the video looks like breaks apart..kind of like the video is being slit horizontally in different places. It looks the same as when you play a computer game with Vsync disabled. If it is set to always enabled, the picture looks fine. I also have a hard time seeking with this plugin.

One last question. No matter the HD movie, I have to always find out what the audio sync offset is. They are always out of sync. Someone mentioned using the nero file splitter has proper sync. Is this installed with Nero Ultra or what? I am curently using the following with 1080i MPEG2 Transport Streams:

Source Filter: DVBPortal HDTV TS Pump
Audio Video Splitter: MPEG2 Demultiplexer
Audio Decoders: AC3 Filter
Video Decoders (good 1080i, 720p): nVidia Video Decoder (filter from TheaterTek)
Video Decoders (bad 1080i): Dscaler filter from this thread

Thanks for the successful effort kzeuh!

Thanks again kzeuh for your continued work on this very importent feature with all those non and badly flagged ts files out there. It's still working great here and I could not live without it anymore.

What does it actually do on non-hd content? Is it ignored or does it try to do the same thing. I keep it just enabled when watching dvd movies with zp and I have not seen any negative side effects. Which is very good as it does mean I dont have to fiddle with settings, just watch movies

Nero splitter comes with the Nero software such as Nero 6 reloaded. It doesn't appear in the Zoomplayer customised filter list, you have to "add" it as a filter in Zoomplayer and search down for the Nero file/splitter filter. Also tick the "This filter is also a Splitter Filter" for it.
AC3filter wouldn't work with my Nero, DScaler5 video, combination, it kept freezing after 5 seconds. I have to use the DScaler5 audio filter instead, which actually works great.

That is the spirit kzeuh!

By the way Ralf, John is right, you can't make a dime off your idea... your work is derived from DScaler, all shape and form and is bound by GPL.

Hi,

Yeah ok....but i must do some cleanup (remove old and experimental code+ comments) and maybee maybee i implement such sequences for anime (5:5,6:4,8:7) if it's not to much hassle.

This will take a few days...

But there need to be work done on the speed...hand optimized asm for amd64 anyone or maybee as suposed multithreadning (i.e. one thread decodes the mpeg the other compares the fields + deinterlaces if video material) ?

And how do we access the CVS ?

On my last post, I had forceware version 77.77 installed and using a GeForce 6800GT

I just updated to version 81.95 and also updated my TheaterTek to version 2.2 so I could have the newest nvidia codec that they supply.

Some interesting findings. I think it is bad, but for others, it could be good.


One of the new features for this driver release is: PureVideo high definition MPEG-2 de-interlacing support. This pretty much is true.

No matter which Video Decoders I attempted to use in ZoomPlayer, the video card was doing its own de-interlacing. I was about to write 3:2 pulldown, but I am not sure if it is doing this or not. All the clips I was testing were .TS 1080i movies that had interlacing artifacts. Even though the card was now doing alot of the work, it was not 100%. I would day maybe 90-95% of the interlacing was gone, but you could spot some here and there. Notably during scene transitions.

Ocean's Eleven was now without interlacing artifacts when using theatertek's nvidia codec, DScaler5 alpha codec, powerdvd codec and windvd codec. Before this, movie had interlacing artifacts when these codecs were being used. When choosing kzeuh's Dscaler plugin, the video card and the plugin were fighting over who should handle the video. There was alot of jerkiness and weirdness going on.

One other strange thing, after installing the new drivers, I had to change the Output Color Space of the Dscaler plugin from YUY2 to YV12. YUY2 had a major blue tone to it. Skin color looked blue like an Andorian. The intro to Spider-Man 2 was not red, but blue. Changing it to YV12 fixed it.

I have since uninstalled 81.95 and installed 77.77. Ocean's Eleven is back to its interlaced self. For the rest of the movies, DScaler now applies 3:2 pulldown without something else doubling the work (ie. the video card).

I thought I would prefer the video card to handle the IVTC, but if it cannot do a perfect job (smooth as silk, no interlacing at all, etc) then no thanks.

Anyone else have a 6xxx/7xxx series card with driver version 81.95 installed not happy with the results compared to kzeuh's method?

Thank you UKdude,
the nero source file/splitter Works great for me.The frame dropped is 0 when i play 1080i Winged Migration,and the frame dropped number is much higher when using other splitter.

You just sign up for the list here

http://lists.sourceforge.net/lists/l...erlace-discuss

The main thing that will make life difficult for both of us is that I've made a load of big changes to the structure of the code in order to support replaceable inverse telecine processing, I'd also be very keen that you build any detection off the new difference map (at least for SD) that I'm also using for motion detection. I accept that we'll probably have to make it pretty flexible to allow for HD to run on normal machines.

In DScaler 4 we found that using field difference alone was a good start but that it fails to detect certain types of cadence break quickly enough and is useless for 2:2 detection which is the main thing I'm interested in for SD.

If you get a moment take a look at the code released here

http://deinterlace.sourceforge.net/p...737b8046612c6a

This has a stub film detection dll that is where I'd like to put your routines into.

John

Which player is this in? I think zoom loads up the property page in some wierd way that means that it is "disconnected" from the filter and so exiting the page doesn't save the chnages to the registry.

John

OK thanks, so the post above to kzeuh about what I see as the issues in merging the code. It would be good to see what you've done and also for you to take a look at where I'm trying to go with the code and talk on the list about the best way of moving forward.



I have mmx field diff asm from dscaler, but as above I'm planning a slightly different approach that should perform much better with a wider variety of material.


I'll give out CVS access when I think we all agree what needs to be done, I suspect we're some way from that, in the mean time I'm happy to try and merge in changes as I get them and spend some time reorginising and fixing the post processing chain to allow HD inverse telecine to work properly.

I can confirm that the decoders behave that way in Zoom John. The options dialogue called up without video playing is always at default values and no changes will be written to the registry upon exit. Actual values can ony be seen and changed in Zoom when the filter is called during playback. I never thought this was an issue personally as I always configure that way, but I've seen the confused question pop up many times.

I couldn't wait for the version integrating decoding+IVTC+deinterlace all together and distributing the computational loads across dual-core CPU. if dual-core CPU is powerful enough to complish all this, that is a "dreams come true" to me.

Yeah, I think it would already a dream to see you guys working together as even though this means some more co-ordniation effort, it much more fun for everybody plus seeing Dcscaler-Project moving forward as we all have been waiting for so long.

I tried the nero splitter, and the seek is much better, almost instant now, but the audio/video are badly out of sync...changing delay in Dscaler video and audio decoders did not help. Anybody see this problem with Dscaler and Nero splitter, and anybody find a solution?

Totally, there is no problem in my machine.

John,
can't Dscaler decoder deinterlace in YV12 mode?

Does anyone here know why we can't acces the DScaler Adio Decoder properties via the system tray ffdshow (by right clicking on ffdshow) ?
If you click on Mpeg Audio Filter (yes that's the name given here for DScaler Audio Decoder), then you can't right click on ffdshow anymore, and you have to kill your player (ZP or TT).

This problem only occurs with DScaler Audio Decoder...

How is this coming along?

If your patches are as good as you say they are, I'm sure there are some of us here that wouldn't mind making a PayPal donation to support the cause.

Hi,

In the lasts weeks i played more with the xbox 360 in my freetime

But in the last few days i optimized the 720p pulldown (War of the Worlds caused some problems).

Furthermore i optimized the Field-Field comparison(so that the comparisons are more accurate)... But as this is only 2 days old this is still experimental.

At the moment i rewrite the IVTC (which is at the moment 'spagetti code') so that i can recognize Varispeed (not the same as dynamicly adjusted speed on abc) and other patterns (i.e. Anime for that i need some testmaterial later on when i implemented the 5:5, 6:4, etc patterns).

I will release my version if this is finished.

Ralf

OK. Somebody has to ask. When might we get a new official dscaler release with all the improvements?

Cresent

Can't even give you a wild guess at the moment. I'd like it to be fairly soon.


Ralf

Haven't heard from you on the list, do let us know what you're up to.

BangoO

Don't know, I'll try and look into it.

chenzhaoyi

It's the graphics cards that can't deinterlace as well in YV12, DScaler5 doesn't do any deinterlacing yet


John

Thx a lot JohnAd

Is there an AMD version available? Is there anything that should be checked in the rest of the DScaler options to improve AMD performance?
