Support forum for DG Tools

I've implemented it per spec, so I will just wait and see how it plays out.

I ran AvsMeter on a UHD 80Mbps HEVC elementary stream (main profile, main tier, level 5.1) and got 100fps with 9% CPU usage on my GTX 950. Interestingly, in DGIndexNV with Disable Display set, I got 130fps. The difference is that DGIndex avoids the NV12-to-YV12 conversion when Disable Display is set [maybe the conversion could be optimized ]. I think 100fps delivered to Avisynth for high-bitrate UHD is pretty good.

I'll make an alpha shortly.

I have uploaded to the usual binaries area a test version of 2051 adding HEVC support.

I would appreciate your test results. Even if you do not have a card that supports HEVC, your testing will be appreciated to ensure that I have not broken any existing functionality.

Following is the content of the included file Notes.txt:

DGDecNV 2051 test version
-------------------------

This build adds support for HEVC video. Please be aware of the following
limitations:

* The DGIndexNV.ini file format has changed, so please delete your existing
.ini file.

* HEVC requires an nVidia device that supports HEVC, such as the
GTX 750/950 etc. If your device does not support HEVC and you attempt
to open an HEVC stream, a popup error message will appear.

* 10-bit HEVC streams are not yet supported. Only 4:2:0 streams
are supported.

* Tiles are broken in the current nVidia driver. This will be fixed
in a future release of the driver. Update: Fixed in 358.87.

* Frame/field repeats are not yet implemented. If you have an HEVC
stream with repeat flags, please contact me.

Thank you!

Fixed a regression: audio detection during play/preview of PS/TS was broken. Please re-download.

I look forward to trying it out when I will be back home, after Nov. 24.
Thank you for the continued support of DGDecNV.

I did some first basic tests with my 9600GS for AVC (m2ts), interlaced VC-1 and mpeg-2 sources: So far no issues with respect to the existing functionality......
What is the meaning of the FPS in the 2nd last line of the log file? Looks like a random number.

Good to hear. Thank you.

It's just a dump of what was in the field when the program is closed. It's the display rate for the last preview/play operation.

I've put a 2051 build up there with the MPEG2 bug fixed and all docs updated. I want to release this version so please let me know if you find any issues.

I'm marking this resolved. If you run into any issues please make a thread in the DGDecNV subforum.

Small question regarding the hevc support, is there some correlation between the HEVC support and the Compute Capability from https://developer.nvidia.com/cuda-gpus#collapse2?
Or some overview which gpus support hevc?

Feature sets E and F are what you are interested in. Search for HEVC on the page.

Cards with full HW decode are currently 750, 950, 960.

Thanks for the info!
