DXVA hardware acceleration w/ free open source howto

[rwalker777]

Since I had a VERY difficult time figuring out how to get DXVA acceleration on my 780g chipset this is how I did it (from a clean install, gets harder with codecs already installed).

Goto the download page for Media Player Classic HomeCinema...
Download the Mpeg2DecFilter and MPCVideoDec filters for your OS. If you want .mkv support go ahead and grab the MatroskaMuxer and MatroskaSplitter as well. (Make sure you get the right 32 or 64 bit version).

Extract or copy all the files to c:\windows\system32.
For each file run from a 'cmd' prompt: regsvr32.exe <whatever.ax>

Install the latest ffdshow (make SURE you disable x264 and mpeg2 support, so it doesn't try to use ffdshow for those codecs).

If it works you should see less than 10% utilization on most x264 720p videos, even with .mkv files and it's all open source.

Tips:
Download the MPC-HC standalone player and try the file in there, this does NOT use the directshow installed (they are all built-in). This is great to see what performance and playback should be like.

If you are having problems with other codecs being chosen, change their merit (priority in Windows) with this http://www.free-codecs.com/download/RadL...anager.htm.

You've gotta be kidding, this works? Halleluyah!

I've spent a crapload of hours on this and NOTHING. What driver revision are you running? The latest one (april I'm assuming) doesn't seem to work at all and the beta ones worked half-assed.

Running Catalyst 8.4 and it is simple. One thing, you may have to install the Mpeg2Splitter filter as well. I didn't need one because WinTV threw one in, but would be a good idea to use MPC-HC's Mpeg2Splitter.

This is very similiar to the way ZoomPlayer is setup.

Never heard of Zoom player, but would be great to see an option in the gbpvr installer to install the codecs from MPC-HC and/or have an OPTION to use them and bypass the directshow filter priority/merit issue. I would think this would reduce end user issues and since it is open source, no license issue (I realize gbpvr is closed source, so may be a separate install). Could be kind of how comskip works, where you drop it in and can turn it on or off...

I dont see the need to give these decoders any special treatment, but I'm happy to include them in the supported decoder list for future releases so that its easy for users to select these decoders.

It'd be good if they updated the standalone versions of the decoders though, since they seem to be lagging behind the integrated MPC-HC versions.

So, to get these working in GB-PVR, do I have to edit the codec entries in the setup xml file or is it just easier to get this working outside of GB-PVR by messing with the filter merit and then just selecting USE SYSTEM DEFAULT on the config menu?

You can either add the decoder name to the <SupportedDecoders> setting in config.xml and select it in the config app, or use the 'system default' option and make sure it gets selected as system default by tweaking the filter merit.

problem with option 2 is that as soon as some decoder you may install gets installed the filter merit changes and everything goes to crap and you have no idea whats going on
