It's easy enough to fix with assumefps(25) but it's still kind of a nuisance.

Code: Select all

SIZ 1920 x 1088 
FPS 500000 / 10000
CODED 62844
PLAYBACK 62844
0.00% FILM
ORDER 1
Also, it's said it's possible to use a DGIndexNV index file with DGIndexIM. As far as I can tell, DGIndexIM is nothing but a fairly limited CLI program, whereas DGindexNV has a fully functional GUI interface. I tried downloading DGDecodeNV but of course it requires a NVidia GPU to even start. Is it possible the gap between IM and NV could be narrowed a bit...

In case you missed it, I believe [ Scan type, store method : Separated fields ] may be line showing the largest contributor to the problem.

It's probably a disagreement between the ES frame rate and the container frame rate. However, to be sure, please upload the file to my FTP. I have sent you access details in a PM. There have been some recent fixes to DGDecNV in this area and they could be ported to DGDecIM. If you are motivated enough to give me your stream, I would be motivated enough to do the porting. ;)

Regarding your question about further developing DGDecIM, I suspended further development (other than bug fixes) due to the horrible support from Intel. Nothing has changed to make me revisit that. I recommend that you cough up $50 and get a low-end nVidia card like a 730. You can run it alongside your existing primary adapter and use it as only a CUDA/CUVID co-processor.

P.MKV

I thought I'd read that Intel had budged a tad, maybe I read wrong or it fell through.

And I suppose getting the actual DGIndexNV to do anything without being able to decode would be an impossibility.

I'm still getting used to the difference between MPEG2 and IM... a lot of the options were done by the indexer in MPEG2, I've discovered it's different now but there's no quick way to check.

P.MKV shows as 25fps for me with latest DGDecIM. Did you try with that file or did you cut and remux with MKVtoolnix or something?

Sadly, Intel support is still a joke. The API is also horridly complex compared to CUVID. Let me give you an example of how screwed up they are. I downloaded the latest MSDK and samples. I built the decode sample. It works OK-ish (bob deinterlacing is broken, actually just not coded for. But they offer it in the document and accept it as a parameter). The decode sample works with both SW and HW. OK, fine, I suppose. It would have been nice if they had implemented bobbing but maybe I can go to the VPP sample and see what I can get from there. Ah, it does nice bobbing with the SW implementation. But wait, it fails if I specify -lib hw! It fails in the mfx session init, which is their code and not debuggable. The error code says "not supported" and that is all. I am totally stuck. So one sample works with HW and another doesn't. This kind of crap totally turns me off, because I can spend days trying to get something simple like a session init to work. This is their goddamned sample code, I didn't modify it in any way, but it won't run on my Haswell while the decode sample does. I wasted 4 hours this morning already trying to figure it out.

I could implement a proper GUI for indexing etc. but given the above if I can't get basic decode funtionality working I am stymied.

Again, get a basic nVidia card and you'll be golden. Or get a 1050Ti and have full HW HEVC, UHD, single- and double-rate deinterlacing, GUI, etc.

It's definitely showing 50fps for me.

I just downloaded a new version today just before I posted to check if you'd fixed the problem already.

Code: Select all

SIZ 1920 x 1088 
FPS 500000 / 10000
CODED 380
PLAYBACK 380
0.00% FILM
ORDER 1
DGIndexIM -i "%~f1" -o "%Target%%~n1.dgi"

I just tried the 64 bit and 32 bit version... Norton popped up a warning when I first ran the 32 bit version so it was definitely accessing a different exe.

So I copied everything into a single directory and explicitly pointed at the exes, both 64 bit then 32 bit and still they both said 50fps.

Could you have a newer version than me somehow?

Ivy Bridge.

i7 3770

Maybe that's a factor.

I just deleted every copy of libmfxsw32/64.dll I could find from my computer.

Downloaded a new copy from here:

http://rationalqm.us/dgdecim/dgdecim_b50.zip

Put everything in it in a folder with the mkv. opened a command prompt did CD /d into the directory, copied the full path of DGIndexIM into the command prompt, -i full path the mkv, -o full path the mkv with dgi instead of mkv.

And... 50fps.

Updating my graphics drivers accomplished nothing.

I slip-streamed a fix to b50. Please re-download and update DGIndexIM.exe.
