Re: DGDecIM QuickSync-Enabled AVC/MPEG2/VC1 Decoder vs DGDecNV

Ok, I got it. It was so simple that I must have missed it. It uses the same .DGI files as DGDecNV, so I can choose between DGindexIM and DGIndexNV to make the indexes.
After testing on various H264 HD files (1080p / 1080I) I must say I'm impressed by it's speed compared to DGDecNV (on my GTX-680).
Next I moved on to 4K and alike stuff, but I bounced back !
I could neither DGdecNV or DGDecIM get working with 4K media. This really wondered me as both my GTX-680 and the Intel graphic 4600 do both support 4K decoding.
DGMVCDecode works for me on 4k but as the docs stated, but it's not frame-correct and seeking is a NONO.
I've currently 2 questions :
1. Is >1080 and 4K not supported by DGdecNV v2048 with GTX-680 ? I would be really surprised by this !
Is it just not implemented yet or should I look further at my site ?
I have a dozen files like this, but on every file I got "no video frames" in DGIndexNV (no video is displayed).
I still could create a DGI file, but on loading it in Avisynth I got nothing or a big green screen with "CUDA error" displayed.
Regarding HW, Cuvid and DXVA2 should both do 4k decoding on my GTX-680 /VP5 card IIRC. What could be wrong ? Besides Cuvid, I also tried also in CUDA mode and DXVA mode, but no avail. (all H264 material)
What I noticed was that the "SIZE" parameter in the .DGI was 0 x 0 and the FPS was also something like 0 /0.
2. The same for DGdecIM : 4K decoding should be supported by the HW, but I got nothing out of Avisynth ; the indexing using DGindexIM went OK and the created .DGI's looked OK (correct SIZE & valid FPS parameter).
Is it just not implemented yet or should I look further at my site ?
BTW, is it normal that DGindexIM goes to 100% and then stays that way without returning the CMD-prompt ? It never tells me it's finished, and I have todo "CTRL +C" after it says 100% to end it.
I'm looking forward to your answer ! Thanks !
