Hard acceleration not working in GBPVR, but does outside of it

[gazoo]

The new ATI drivers (beta) are out for the ATI 780g IGP motherboard with HD3200 graphics. I can get hardware acceleration to work in the DXVA checker app for cyberlink 8 with vmr9 and evr, and AVIVO with vmr9 only but not in GBPVR.

I tried EVR, VMR9 custom, and VMR9 FSE. EVR for both AVIVO and cyber won't accelerate (it's not supposed to for avivo, but is for cyber.) VMR9 custom with cyberlink freaks out with stuttering and green screen and for avivo the same. VMR9FSE plays fine, but as AFAIK no HA for either codec.

Are there any ideas as to why this is? Is VMR9 custom REALLY VMR9? Perhaps it's not considered that by the codec and that's why it's not working. However, that would not explain why the freakiness. FSE, is that more like traditional VMR9?

Please, let's discuss.

I'm using the DXVA checker program which lets you play a file via the different codec modes (AVIVO mpeg2c, cyberlink mpeg2b, c, etc.) using different renderers.

There no settings in GB-PVR that would effect this. Its up to the video decoder and video renderer to decide between themselves whether DXVA can be used. I'm also not aware of a single post in the past which showed GB-PVR getting in the way of DXVA being used.

Is VMR9 custom REALLY VMR9?

Yes it is VMR9. The VMR9 renderer has option for apps to provide a 'custom presenter' for drawing each of the decoded frame to the screen. This all happens after the DXVA stuff has done its job.

FSE, is that more like traditional VMR9?

VMR9 Custom and VMR9 FSE are the exact same code, but one askes for exclusive fullscreen access to the video card.

I'm pretty sure your selection of GB-PVR renderer isnt your problem. Its most likely caused by a video decoder that ends up being used that doesnt support DXVA. Have a look in the pvxr2.exe-native.log to confirm which deocder is used.

Thanks sub. I just needed that cleared up so I could go look at specific areas. It's very wierd. I'm thinking it might also be due to the drivers being beta perhaps.

If anyone else has any ideas, please chip in.

Sub,

According to the logs, I am using ati video decoder (as I should), AC3 filter for sound (maybe this might be part of the problem, don't know), and then it says "getsetting(preferredmpegplaybackdemux). The demux might also be part of the issue. It didn't spell out what the demux was (perhaps because it's the default). What's the best way of figuring out which demux it's using - graphedit? In GBPVR, can you specify which demux to use, or should this be done at the system default level outside of GBPVR?

Ok, I went into a little more diagnostics. In WMP, it's using ffdshow for everything. That means no DXVA in wmp, but I don't really care about that - I want in GBPVR. So question one would be, what is an MPEG2 1080i filter supposed to look like? is it source->splitter->mpeg2decoder->output or is it source->demux->mpeg2decoder->output? (I purposely excluded audio for now to simply).

IF demux is the correct way, how do I set the demux in GBPVR? Or do I have to do it system wide as I said before? I have no problem tweaking filter merits and such, but I would like to know which one. I have attached a picture of my Gspot output and highlighted all the mpeg related stuff. I don't know which one to choose to be the demux from the ATI list because they don't say demux, but say mux instead. However, there seems to be one prevalent file of interest in there from ATI which is atidvcr.dll.

I don't know. Any thoughts (sub or anyone for that matter)?

It wont be to do with the demux. It could only really be the video decoder, or the videocard drivers not correctly supporting DXVA. GB-PVR nearly always uses the MPEG-2 Demultiplexer filter, but even the MPEG-2 Splitter would be fine for DXVA.

I'd try other video decoders that supposedly have DXVA support.

Could this anything to do with this comment about cyberlink 8

"Oh yeah, it also wont share it's directshow decoders with any apps; not even Windows Media Player 11... or anything else; unless there's some undocumented way to force them to be used in other apps."

Ok, any other suggestions on DXVA capable mpeg2 decoders? I have avivo and cyberlink, but those don't work right for me.

I'd try building up some graphs manually in GraphEdit to see if you acceleration working.

Sub,

I just did a simple source->ati decoder->vmr and it worked fine in graphedit. HOWEVER, I'm not so sure that the vmr I used was 9, it may have been 7. I right clicked on the vmr renderer and it said on it 'vmr 7 is non-mixing mode'. Don't know if that means it was a vmr7 renderer or not. I'm am currently switching out my hdtv so I'll have to report back when the new one is in later or tomorrow.
