the following were my results from encoding a 1080p avc stream croppped at resized to 1280x528 (via avisynth). I did it the three different ways that I know, of dgAVCdec , dgAVCdecNV and finally, wrapping the stream in the matroska container and loading it with directshowsource
The stream was 20 seconds and had an average bitrate of 30 and a max of 41 I am encoding with 2gb ddr2 ram, 1066mhz, a Intel CPU, Q6600 / GeForce 8800GS 384mb DDR3 ram. 1st pass 2nd pass dgAVCdec 100a26 14.61 fps 7.55 fps dgAVCdecNV 108 23.76 fps 8.11 fps ffdshow-libav 19.73 fps 7.65 fps to be quite frank, I was really expecting a bit more... So um... I'm not a programmer but are there any plans for down the line, having the GPU handle cropping and resizing as well ? I took the encoded 1280x528 steam, indexed and encoded it the three different ways without any resizing and got the following results. 1st pass 2nd pass dgAVCdec 100a26 26.52 fps 9.98 fps dgAVCdecNV 108 30.19 fps 10.14 fps ffdshow-libav 26.96 fps 10.00 fps So it would appear to me that offsetting the decoding of the stream itself bears very little benefit but if it could be used also to handle resizing of the image, then that would result in a 30% speed increase. On another note, (and I did 1st do a search of the thread for "saver" and didn't find anything but i'm sure this has point has been raised before), I have had to disable the screensaver.

@jonathonsunshine: "to be quite frank, I was really expecting a bit more..." Why? Decoding normally is not the major work that needs to be done during reencoding to h264. If you use high speed settings with (--me hex, --subme 1,..) speed difference might be higher, since decoding speed will become a greater factor.

Why are you using such and old version?

has development started on an ATI version of this app yet neuron or are you waiting for their equivalent of CUDA to improve or waiting for API's that will allow you to create an ATI version?
This app is looking very nice indeed. |

regarding license.
I just donated and got the license. I am going to return my new graphics card and get a different one ("Point of View" vs EVGA, both 9600GT) since its too loud and the fan not controlable. Not automatic or by software. Do I need a new license for it afterwards? Best regards |

You won't need a new license.
BTW, my BFG 9600GT was making noise too, but it was a subtle "chirping". It turned out to be a small piezoelectric speaker intended to alarm an undervoltage condition. I'm sure there was no undervoltage. Anyway, I just covered the little exit hole of the speaker and it's inaudible now. |

Version 1.0.9
1. Added support for the new audio types found on BluRay disks.
2. Improved the audio delay calculation. 3. Removed the Treat I as IDR option as it is now always enabled. 4. Machine ID now not tied to system partition, so machine ID changes will be rare. 5. Updated the CUVID server to 1.0.3. http://neuron2.net/dgavcdecnv/dgavcdecnv.html Last edited by Guest; 10th January 2009 at 17:29. |
