When I start the job it seems to be slower than I'd expected -- about 125fps. So I stop the job and restart it. Suddenly I'm getting 420fps... with the exact same command line. Try it again... and it's random. I might get either of the two speeds. Weird.

Now THAT's confusing.
An app being quicker on second run is no mystery, happens with sore more SW.
Its just that these date are still kept in RAM.
Like with tsMuxeR, muxing time went from 9..10 min first run
down to 1,5 minutes for the same 10GB test stream on second and third run.
(Magnetic platter HDDs used, with SSD maybe unnoticeable)
I just extensively tested for one particular stream losing packets at the end.
(solved since the 2020-06-27 build for me, BTW)

Would fit the available 32GB RAM. (Did not run RAMMap though to confirm)
Why it would be slower on third run, I cannot comment.
But if I close the app and allow the RAM to be flushed, then it may take the full first running time again.

hmm im only get 66 FPS regardless how many time i restart, just a note 400 fps sounds too quick, gpu encoding doesnt give same quality as cpu, so id be happy for gpu to be spitting out the best quality it can do "--preset quality" even if that means less fps, im sure gpu at max quality will be a lot quicker than cpu, will be nice to have the option of HW excelearion, will you be including 264 hw exceleration also ?

i'll experiment with the updated version. I'll have to go into the bios to enable the iGPU. That's a job for upcoming weekend.

I've deleted it. Right now I'm in the middle of system backups, but I'll post an example later.

Thanks.

Wow. That's are really quick response! I just downloaded it and will do some testing after my backups finish. I added code to BD-RB yesterday to scan/add the headers -- but I'm very happy to remove it! I'd much rather have the encoder do it!

I think you mean acceleration. Also, when posting long lists like that, please CODE wrap them.

I'm guessing you are talking about a 2160p source. The one in which I was getting the goofy numbers was a h264 stream at 1080p.

Just a head's up. I tested the new version of NVENCC yesterday, and the new option to include headers results an encoding failure with a "Cannot allocate memory" message. Removing the new option from the command line makes the encoding error goes away. But, then, of course you're back to having the FF/REW/CHAP issues. I posted an issue report on GITHUB. It appears that the new option creates a memory leak (as can be observed by watching the process under the Windows 10 task manager). On the 32 bit version of NCENCC it hits the memory limitation pretty quickly (you have to use the 32 bit version to remain compatible with AVISYNTH 2.60 -- which must be used under certain circumstances).

So the options right now are to wait and see if it gets another quick fix, or to go ahead and implement the code that adds the headers within BD-RB. I'd prefer the first option, as that's a cleaner way to go. So I'm going to wait for a bit and see what happens.

Id wait a while and see if it gets fixed, i can also conform its eating memory, at frame 69522 it consumed 1.6 gig of memory and then errored, im running 16 gig but according to task manager i was only at 50% mem ussage ?

unfortunatly not not good news

Please try with x64 build of NVEnc 5.08, it should not require nppc64_10.dll now.

It might be a memory leak but it's difficult to fix, as "--repeat-headers" only sets a parameter provided by NVENC SDK, there is little I can do here.

Yes, but issue 246 seemed to develop with 5.07 has been resolved
Running a quick test, to see if it finishes

The issue is still there. It will probably have to be fixed by NVIDIA.

It's very obvious. Try this:

1. Run NVENCC with the --repeat-headers parameter
2. Open up Windows Task Manager and click on "Details"
3. Watch the memory usage for NVENCC.EXE.

The application's memory usage will continually rise (pretty quickly) until it eventually runs out and the app crashes. It's just more obvious on the 32 bit version because of 32 memory limitations.

Even if you use the 64 bit version, the memory usage keeps growing (at least on my system). But the application is less likely to crash since 64 bit apps have much more memory available. I can use the --repeat-headers on the 64 bit version with a 2 1/2 hour movie and it will complete. But... the application is using about 600 Megabytes when it starts then slowly increases to point at which it is using over 2 GigaBytes when it finishes.

Who knows? It may act differently on your card and/or drivers.
