HW acceleration for VC-1 codec? - Green Button - 06-15-2012 08:14 AM
I've backed up some BDs to my PC hard disk... and of course while most of them have MPG4 content, there are some that have VC-1 in 1920x1080.
All the MPG4 ones play just fine on my PC (a niveus "zone" -- not a big fancy graphics card in there) but the VC-1 ones drop a lot of frames.
Are the VC-1 codecs here accelerated by my graphics part? Is there anything I can do short of "buy a new PC" that will make these play smoothly?
thx

On the SWAP TAB, select the LAV option for VC1

If you use LAV video decoder, then you must enable hardware acceleration for your graphics card (eg. Intel QuickSync for Intel grafic) in LAV decoder under "H264".
With ATI or NVIDIA graphics, you can also use FFDshow DXVA for VC1.
But beware, if you change the VC1 decoder under "SWAP" something will change under "MPG~MP4" and "MKV" and turned automatically to "Gabest splitter":

Depends on what graphic card you have, you did not mention that.

It's just a motherboard with built-in graphics -- it's Mobile Intel 45 Express Chipset Family (with Microsoft WDDM driver).
When I choose "Intel Quick Sync" in the Hardware Acceleration section of the properties dialog, it says "not available" next to the dropdown. (and Active Decoder says <inactive>)
If I choose DXVA2 (either mode-- copy back or native) it says "Available"... and Active Decoder also says "inactive" but there's checkboxes checked for H.264, VC1 etc. underneath.
Is one of these the best choice?
Thanks again for the help/advice
ps - I noticed that even if I check these, on the "formats" tab down at the bottom it still has checked "Use Microsoft WMV9 DMO decoder for WMV3 and VC-1". Would I want to UNCHECK that as well?
thx

Your on-board Intel graphics dominated probably no VC1 hardware acceleration.
Since this is a mobile version, I suppose that you have no separate video card,
for example ATI HD6450 or NVIDIA GT 520/620 can connect?

Also you could try also the MPC-HC codec (H264 Tab in Shark´s app), then check formats and select VC-1 (DXVA). It will probably not work if you are not using MPC-HC.
As for if to use Quicksync, DXVA2 (native) or DXVA2 (copy-back) - test it on your system and choose which works best for you (in case you get the HW acceleration working).
