LAV Filters - DirectShow Media Splitter and Decoders

[noee]

Athlon II @ 2.2Ghz w/HD6570, Win7 x64 Ult

HD: 77fps
DXVA2: stops at the end of the first pass, no stats, same as the failure I listed above for the 6520.

Yeah, I'm pretty sure it just stops, I waited a couple of minutes, it says :18/:18 and then it just sits there, GraphStudio is responsive at that point. Not sure what to make of that.

Does this mean there is no hope for ATI HW deinterlacing with MadVR? For now the workaround for me is to use EVR.CP when I want to watch an interlaced video (which thankfully for me is a minor thing). I could alternatively run ffdshow raw video filter + yadif SW deinterlacing but I'd rather keep my filter chain as direct as possible. (LAV splitter - Lav Video - MadVR/EVR)

I dunno. Inside a renderer, there are other possibilities. AFAIK, only the download of the image is so super slow, which could be avoided if you jsut use that surface to render it.

Maybe there also are some tricks to make it faster, but i don't have any ATI hardware to test things on.

The odd thing is, somehow VLCs DXVA works on ATI/AMD as well, and they copy the image back from a D3D surface as well, so there must be some trick.

Same for me, with DXVA2 its pretty much a slide show.

Just hope the AMD HD 7xxx will solve this.

I heard you can StretchRect to RGB render target and then GetRenderTargetData on ATI, but having to convert to RGB doesn't impress me.

Not that I care much for interlaced content, or think the aged hardware can handle it, but both my laptop's integrated Intel and nVidia graphics are failing with same kind of error:

Intel GMA HD http://tinypaste.com/32bd1
nVidia 310M http://tinypaste.com/59667

Sounds like whatever renderer you're using doesnt support NV12.

Anyway, the main point of info i got today was that ATI/AMD is still too slow in this area, and sadly doesn't even support DXVA-HD at all.
Personally, i use NVIDIA in all my systems, so i don't care that much of a great deal. That Intel supports DXVA-HD is nice, although its also too slow (NVIDIA 200 fps, Intel 30 fps) - but it leaves me hopeful for future Intel drivers/IGPs

Since i want to move away from hardware decoding due to some limitations and annoyances of the black-box decoders, i'll continue this idea, and see where it brings me. LAV Video + DXVA-HD processing to deinterlace .. sounds like a good plan!

Nev, do you have any idea why I only got ~93 fps with the test build? I have the same gfx card as you do.

Because LAV Video uses the CPU when decoding. The GPU only affects how many fps you loose when using the DXVA-HD API...
You probably have a slower CPU.

EDIT: nvmind. missed your CPU image. nevcairiel's comment cleared it.

Thats not it, his CPU image also shows ~240 fps.

Its probably some setting in the NVIDIA control panel, like forcing a high level of AA system-wide, or enabling things like noise reduction/edge enhancement.
Its also running in the "Playback" preset, which means it doesn't go up into the next performance mode as long as its fast enough for the FPS i gave it.

[SamuriHL]

Yea, turn that crap off if you wanna do video.

[Xaurus]

I thought I had disabled all that stuff so I took a screenshot of the settings, please see screenshots below:

I've been trying to get regular DVD iso images to playback via LAV. Is this not supported (menu and such)? No problems using default MPC-HC setup.

My External Filters setup:
Lav Splitter v.35
Lav Splitter Src v.35
Lav CUVID v.12
Lav Audio v.35

Am I missing something? Thanks.

[Midzuki]

@ nightfly: No, LAV Splitter is not a DVD navigator, and LAV Video does not include a subpicture decompressor (which, BTW, would require a major fix in ffmpeg/libav).

[fairchild]

Yeah to watch DVD's you need to have another video decoder installed in system which can decode DVD. I use ffdshow libavcodec and it works just fine with DVD Navigator + Lav Audio. I can play DVD's with either MPC-HC or PotPlayer just fine. I'd imagine you could also use your video player's internal codecs as well if they have some that support DVD decoding (MPEG2 + DVD decoding).

Oh yeah I forgot to add, if you bypass the DVD menu's and just open the individual movie VOB files, then Lav Splitter + Lav Video + Lav Audio work just fine for me.

Here is another version, this one uses DXVA2 Video Processing, instead of DXVA-HD.

http://files.1f0.de/lavf/LAVVideo-dxva2vp-test.zip

This should probably work on ATI/AMD.
Same rules and restrictions apply.

BTW, its not tuned for quality or anything at all yet. Its just to test device capabilities and speed.
Its also a debug build, which is generally slower then a release build.

I cannot register it, what is missing? Module failed to load.

[nevcairiel]

It requires Windows 7, on XP it won't even load.
Sounds to me its just not finding the required libraries (which are not present on XP)

2 missing imports in XP:
Direct3DCreate9Ex() in d3d9.dll, according http://msdn.microsoft.com/en-us/library/cc656710.aspx you have to use Direct3DCreate9() instead.

DXVAHD_CreateDevice() in dxva2.dll, you may use dynamic loading instead.
