We're having so much fun I decided to try with GPU encoding for this use case we are discussing:

DGSource() + NVENCC + 2080 Ti + 7700K: 1:05.

I tried to choose settings that produced results perceptually approximating x264 medium.

Isn't the video decoding done in a separate PureVideo decoder chip which may not have developed as much as the 3D rendering and shader operations? ... The closet was the room with the least needs for space in this house.

Also the number of lanes that the CPU has with the GPU is important. For instance, Xeon CPUs like the W-3265M has 64 PCI-E lanes, while its consumer counterpart probably has less lanes. The thing is that it's not only a matter of GPU, but also a matter of which CPU you are using. As a matter of fact, having a very good GPU with a not so good CPU will limit its efficiency.

Can I safely index MKV (hevc) with audio tracks and subs for now? I read somewhere earlier that i need remux MKV with only video track for better indexing, cuz another tracks can impact on accuracy.

Quite right, LigH. Seems to me that the main nVidia development effort goes into gaming-relevant things. We really need super high PCI bandwidths too.

Fairly safe. It used to index all other tracks and would create huge index file. Now they are all skipped. Let us know if you hit issues again.

@HolyWu, I built LSMASHSource from your repo using this CMake file taken from @MeteorRain repo. When tested for seeking issues with that file my build has errors but your build is fine. Something wrong with my building process? ffmpeg 4.2.1 / 4.3 used without difference.
There is patch for replacing avresample with swresample in your repo but avisynth exlibs - #pragma comment( lib, "libavresample.a" ).

@HolyWu ,I downloaded your build from release page of your github but there is no vsLSMASHSource.dll in folder.
Does it support vapoursynth?

It works for avisynth and vapoursynth.

R47.2 is buggy. Stick with R46 or go to latest R48 test. It contains fixes for all spotted bugs of R47.

Question: Would be possible to use multiple threads to speed up indexing process? For example by using some kind of chunk indexing?
I'm asking because NVMe SSDs with read speed of 3GiB/s+ are getting much more affordable. I have Xeon E5-2690@3.2GHz (8C/16T) and I see that i'm experiencing a bottleneck due to single threaded code.
In this example I'm indexing 4k movie (~50Mbps) from RAM disk...

1,24GiB/s is a max I can get on single core. ffmsindex is even more cpu intensive (only ~0,5GiB/s).

Currently indexing of ~60 GiB 4k movie takes ~1 minute. With proper multi-threading we could easily reduce indexing time to ~15s!

Uploaded new binary which ditches libaom and is built by clang-cl. The binary size is smaller than the previous ICL build and decoding speed seems to be marginally faster.




No problem. Here.
Your Latest still error with .vp9, add this video and check

Maybe you are asking the wrong question, how about MakeMKV creating an index? Answer: It's just code, anything is possible.

Stop indexing progress spamming

-- Now only refresh at every 1%.
Still error with vp9, only old ver r929 of VFR-maniac still fine
