ffdshow Video Decoder?

[DFA]

xlr8shun:

One other thing: do you have a NVDVD 2.0 - 2.55 license installed? The beta NVDVD 3.0 looks for this license. From personal experience, I can tell you that without it, the codec will briefly start up then close down. I was not observing the behavior of the tray icon, but would get a brief glimpse of video and then the codec would close. Sage will error (I don't recall with what complaint) but does not know what the deal is. Sound familiar?

If lacking a license, you can purchase NVDVD 2.55 at NewEgg for 7 bucks.

I went here and gave myself a refresher. It has been a while since I had read it. In addition to the CUE, I had forgotten about ICP (Interlaced Chroma Problem). ICP looks a lot like CUE. As I understand it, the simplest and best fix for it is low-pass vertical chroma filtering AFTER deinterlacing. I think this is what Stanger89 has accomplished.

I also have the impression that the nVidia codec does not do any deinterlacing when a post processor is detected. This is based on what I am seeing on the applet when ffdshow or NV-VPP is plugged in. For ffdshow plugged in, the nVidia codec applet says "Best available" which is the nomenclature for Overlay deinterlacing instead of saying "VMR default" (pixel adaptive, median, or vertical stretch). Either that, or the codec is in Overlay since "VMR9 prefered" is not a fixed setting but a will-do if can-do setting OR neither, really, since the post processor must determine that.

Any thougths on that? I'm just speculating and not claiming to be accurate. Just trying to sort things out a little bit and understand for myself.

doh.. you were right, it was trying to use nvdvd 3 (as that had a higher merit then the rest) but failing, hence the flash of the icon in the tray, so then what i did was uninstall all codecs, installed elecard 2.0 (with the logo) and nvdvd3, sure enough, sage uses ffdshow, ffdshow uses nvdvd3, fails, flashes the icon, then reverts to elecard (i can see the box logo in the corner).

i installed a licensed copy of nvdvd...

weird, gotta install nvdvd2.x, to use 3.0, but cant have 2.x installed when 3.0 is installed..

in anycase thanks dfa, i like the quality of 2.55, might just stick with it, however im gonna uninstall it now, so i can check out 3.0 (hope it works this time)

I have loaded ffdshow with the Moonlight latest decoder. I am running a Radeon 9500 and I would like to change the brightness and contrast? How? Please can you detail because I am new to ffdshow and I am trying to figure my way around. Thanks.

IMO, the decoder stage is not the right place to adjust the brightness/contrast, that should be done at your display and/or capture. What I do, is calibrate my display to my HTPC using Digital Video Essentials, that way DVDs and everything will be just right. Then I use the dScaler histogram filter to set the capture brightness/contrast so that the files are encoded at the correct levels. Sage's recordings are also MPEG-2 and decoded by the same decoders so if captured correctly they should therefore be decoded and displayed correctly that way.
