WMV9/3 is handled by the VC-1 decoder in DXVA2

I'll possibly add MPEG4-ASP to DXVA some day, but ffmpeg doesnt have support for it yet, so it is a bit more effort.

Thanks

With this sample, CrowdRun_2160p50.x264.CRF24.mkv. Its to be expected not to decode properly on any hardware with DXVA copy-back? When I test its very slow and 1/2 the screen is green (GPU load is always under 20% and CPU under 5%)

If the hardware claims it supports such a resolution, it'll most certainly try to decode it.
Sadly i don't have any hardware to test this on (yet), mine just blocks the attempt at using DXVA

So WMV9 includes all three profiles of VC-1.
Confusingly, the mediainfo from my HD wmv clip says VC-1 and WMV3- I thought WMV3 was older standard?

VC-1 Main Profile (MP) is 100% compliant with WMV3. Only Advanced Profile is new in VC-1

I see, thanks, so should this be accelerated with NVidia 9800GT on the current version or on the next LAV version? DXVA Checker lists

ModeVC1_IDCT: DXVA1/2, 720x480 / 1280x720 / 1920x1080
ModeWMV9_IDCT: DXVA1/2, 720x480 / 1280x720 / 1920x1080

The CUVID decoder should be able to use that, yes.
Its only partial acceleration, but better then nothing.

So are you saying CUVID works now but in the next version DXVA will be better? I just found this document searching for diff between VC1_IDCT and VC1_VLD, dunno if this is any use to you

possible problem.
my friend was playing an mkv, and within the folder that the mkv was in was an mka with the same file name.

This caused another instance of lav splitter to open, which caused another lav audio to open, and he had multiple audios playing at the same time.

I believe the audio was AAC in both files, but I'm not certain.

the player used was mpc hc v1.5.2.3456, lav audio .44 and lav splitter .44.

That's likely a feature for playing video and audio streams from separate files, same as you can do with subs. Just change the file name or put it in another folder. (mka is matroska's audio container just in case.)

Here is also a second test version for users of older Intel GPUs, it may or may not improve things when using DXVA2:
http://files.1f0.de/lavf/LAVFilters-...2-test-gma.zip

I'm only going by some documentation i found, i don't actually have such a GPU.
Thanks for this test build, I assume you're now using 0.9.x or the latest git master of ffmpeg now because this build at least in my tests has improved seeking in H.264 greatly, before when I would use LAVFilters in combination with madVR there would be a bit of a lag when you tried to seek, but now it's instantaneous and I noticed 'update ffmpeg' a few times on google code.

CUVID supports partial acceleration, my DXVA2 does not and will never. Only VLD in DXVA is supported.

Thats a MPC-HC feature. You can either turn that feature off completely (Playback -> Auto-load audio files), or just enable the internal Audio Switcher, which will allow you to choose which file is actually output, instead of outputting both.
LAV has zero influence on this.

PS: it seems independent from the choosen vid mode : softw, CUVID en DXVA all report the same (Lav-splitter is sending 6 fps this downstream)

Can you upload a sample - for test with MPC-HC, i try to fix.

Its in src/DSUtil/MediaTypeEx.cpp, line 72 and 82, the TrimRight will remove all extra zeros and dots, so 60.000 becomes 6 and 30.000 becomes 3.
To preserve the current functionality, do it with two TrimRights, first trim zeros (60.000 becomes 60.), then trim a dot. Don't trim both at the same time.

That's what I though first... but then I realised that ffdshow is also bitstreaming EAC3 to my hardware, and audio renderer is connecting with no problem... ? May be ffdshow is fooling the renderer...

But ok... I'll need to investigate a little bit more. I'll try downgrading to 0.43 or lower, as I don't remember to have seen this problem before. Anyway, not a big problem disabling bitstreaming for EAC3 if that's the case.

Thanks a lot.

Bitstreaming didn't change at all for quite a while, i doubt the issue goes away.

I usually update quite frequently (always against master), typically at least once shortly after a LAV release (so that any bugs that might come from ffmpeg can be resolved until the next release).

CUVID decides to not use DXVA for that sample and call the GPU directly, who knows whats wrong with that. Maybe i have some time another day to look.
