Well I have avoided stupid things but there are some things that still need to be investigated. The connection to DX/D3D is a possible area for improvement. But I'm pretty happy serving 1920x1080 46fps @ 2% on my machine. As long as we can feed x264 faster than it can encode, we are golden.

BTW, any word on the CoreAVC API/SDK?

Yes indeed, I'm glad you have this here now. Having my CPU usage for decoding basically halved (perhaps a third even, my desktop has a faster GPU) is a godsend.. Goodbye 0.7 fps decodes!

I absolutely cannot wait to test this on my monster of a setup.. GPU decoding on my desktop with a 9800 GTX, filter using MVDegrain3, pass it off with TCP serving to my laptop and encode it.

I've gotten a bunch of spontaneous errors before.
And now trying it again, it's no longer working at all; spitting out some of the standard 'no supported GPU' errors

The PureVideo deinterlacer looks REALLY good but reduces the frame rate by 25% (i.e., rate is 75% of the rate without deinterlacing) on full HD. I'll expose it as an option in the next alpha.

Awesome!!!

Currently downloading the CUDA driver for Vista x64 here... I *thought* I had it installed, but it wasn't working (the cuinit error).

Will report back ASAP!

Thanks Don!

Okay, so i have the CUDA driver installed, and when I open DGAVCIndexNV I get the "failed to find CUDA compatible D3D device" error.

I have an 8800gt, which is both CUDA and DXVA compatible.

Vista x64 being a naughty little child perhaps?

Has anyone else gotten this working with Vista x64?

Where do I get DGAVCDecodeNV.dll? It's not included in the zip file.

You'll have to do some research over at the Nvidia CUDA Zone website. Let us know when you find out.

You have to pay extra for that.

[Just kidding. I'm still working on it.]

LOL

I have Windows XP Pro SP2 x64, and a GeForce 9600GT 512MB. DGAVCIndexNV worked for a while (with bugs, explained later), until each time I started it, it wouldn't find my video card. I copied the files as mentioned, installed the CUDA driver and toolkit, and rebooted, and now it appears to be working again.

So, bugs.

1.) There is a significant amount of artifacting during playback in the indexer with DS's x264-encoded Touhou sample (here), and especially the lossless Touhou sample (here). I don't know if it's also in the decoded stream through AviSynth+DGAVCDecode.

2.) If I play either of those samples in the indexer, and then quit before stopping playback (with display on) I usually get the errors "cuvidMapVideoFrame: 201" and the same with the number 205, after I exit.

3.) In the lossless sample, if I seek to the middle of the video and then hit Play, the video does not play and no info is reported.

...and now I get the CUDA-compatible D3D device error again. :/


Thanks for your work, neuron2 Can't wait until this works well - it was able to play the non-lossless sample at 147+fps with no CPU usage (display off) before it stopped working. Promising

Let me know how you like the deinterlacer.

Is that the only change? If so, I won't test it, as there are critical problems on my system right now with it. But if there's fixes, I shall test and see if it works better.

Great work

MP4 and MKV files are not yet supported, just as with DGAVCIndex.

I used the demuxed .h264 stream.
