the middle of page 77 has some info on it, but I believe you need to checkout the device ID from the logfile or something?
OBS branch with AMD VCE support.
- Thread starter jackun
- Start date
I read through page 76-78 but could not find what I was looking for. Am I blind?
Yes, it actually started in the middle of page 76:
Ah thanks. Seems like halsoy is running Crossfire but I have sooo much trouble with it. Is it possible to do it without Crossfire? I am confused about where I should change the AdapterID. Jackun wrote that I should open profile ini, but I cant find that file in my OBS folder.
First of all, thank you very much for investing your time into that project jackun, to give people like me the great opportunity to record gameplay in 1080p and 50-60fps with max details without any impact on the game! Its just amazing!
But i cant help asking here for an anchor point where i can get better information about the VCE options, even after testing on my own and research for quite some time.
When i switch on "use custom parameters", the preset of "speed" and "balanced" works just fine, but i cant realy notice a difference in terms of performance or image quality, but should i?
If i turn on "quality", i just cant render, no metter what bitrate i choose.
I dont know where to start to optimize, do i have to optimize the size of gop?

Jackun has put links on OP for a few explanations of some of the settings. the quality preset does not work with 1080@60.
as long as you have enough bitrate for your recording, balanced and speed should not be a whole lot different. I'm talking 50,000kb/s for 1080@60. If you dont notice the difference, set it to speed as not not waist resources.
GOP is one of those effeciency of the encoding. a higher GOP will give you better picture quality at the same bitrate of recording. a GOP of 60 (for 60fps recording) should be plenty though, and you could even say that for speed purposes, you could to a GOP of 30 (which is what youtube recommends anyway.
I have two 280X in my computer. They are running separately, no crossfire. I went into AppData\Roaming\OBS\profiles and added AdapterID=2 under [VCE Settings] on the profile I am using. Tried to record, but I instantly felt that the FPS dropped. I would appreciate it very much if you could help me out with this problem.

I don't see any D3D11 device enumeration from ObsVCEAMF. Make sure Engine Type is Dx11 (maybe Dx9 also works, I can't remember) and then set AdapterID=1 (index is zero-based). And since you're on Win7, you'd probably be better off also enabling D3D/OpenCL interop. (needs Dx11 engine type) as Win7 doesn't have NV12 Dx11 texture format support :(

Thanks for the reply! I changed the AdapterID to 1, but where do I change the Engine Type? In the profile ini I can see AMFEngine=0, is that what I should change?
Oh, I found it. Tried DX9 and DX11. DX11 gives me least FPS drops, but I can still feel an impact on the FPS when recording. :/
Yep, that is right. I just noticed that OBS is changing AdapterID=1 to AdapterID=2 all the time so I changed it back to 1 and set the ini file to read-only.
Here is a log file of the latest settings: http://pastebin.com/yPebTJwv

You probably have to close OBS then before you manually edit the ini as ObsVCEAMF only reads the AdapterID value and doesn't write it to ini itself.
It is still missing something. You should see something like this after "Build date" line

It says AMF DX11 : Using device 0: Device ID: 6798 [AMD Radeon R9 200 Series] but should it not be using device 1?
Okay, thank you for doing this! I am not running the cards in crossfire though, but I should mention that the second card is sitting in a PCIEx4 slot. It cant have anything to do with the topology id, no? http://i.imgur.com/mS0mFGv.png

Ok, then I'll add some more logging as to why it ignores the second card. TopoId is used with the older OVE api, not with AMF.
Ok, good! So I guess all I can do now is wait? Also I saw you mentioned that I would be better off using NV12 Dx11. What is it that would be improved if I would use NV12?

Ok, try this and post the log.
Nah, better off using OpenCL interop. (which you have already enabled anyway) because Win7 doesn't support Dx11 textures in NV12 format for what ever reason.
