OBS branch with AMD VCE support.

Github repo for the branch.

I've implemented some support for AMD VCE, you may read about it Here at AMD's blog.

There is currently 3 implementations: with the older OpenVideo encode API (OVE) and with AMD Media SDK (Windows' Media Foundation transform aka MFT).
As of now, with Drivers 15.7 and above, OVE is no longer possible since it has been phased out to be replaced by AMD's AMF(Framework) entirely.

If you have a qualifying:
GCN 1st/2nd generation card, up to 1080@30 or 720@60 can be utilized with the "Quality" preset. Anything above that (1080@60) will need either "Balanced" or "Speed" presets which can all be found in the AMD VCE Settings tab of OBS.
GCN 3rd gen card, up to 4K/30fps (untested, only with AMF) but should do 1080@60 easily with Quality preset. After testing, this still doesn't work, might be the SDK.
GCN 4th gen card, up to 4K/60fps (untested).

GPU heavy games can cause frame freezing. You can try disabling D3D10 interop (and with AMF, select "Host" engine type) so that encoder preparation work is done on CPU instead. But then there is the issue of copying stuff into GPU VRAM so it might not give any performance boost.

OVE version can use OpenCL for colorspace conversion (YUV444 to NV12), but it is currently done before passing the frame to be encoded. It adds to encode time and can make OBS drop frames so it is better suited for 30..50 fps recording and low performance CPUs, for now.

For clarification:
  • AMF: OpenCL interop assumes that the video adapter OBS uses also has VCE support. There's a secret AdapterID setting that may or may not work for selecting another adapter.
  • D3D & OpenCL interop doesn't have anything to do with games, only with OBS as it uses D3D10 to do its magic. Ticking it makes OBS use CPU for NV12 conversion instead and on Win8+ DX11 engine will use NV12 textures. Dx9 and Win7 resort to using host memory for NV12 buffers.
  • Device TopoID is the 'physical' location on motherboard, not device vendor ID etc. as you can have more than 1 device with same ID. Check log (window). It only affects OVE because if I'm not missing something, you can't specify device for AMF (yet). But it could be using the device that AMF context got init'ed with. If that's the case then it uses the selected device from Video > Video Adapter.
Installation and Prerequisites:
1. You will need to install MS VC++ 2013 runtimes. For Simplicity, It is recommended to install both x86 and x64 for 64based systems but if you only use x64, then just install the one.

2. (7-zip or WinRAR) or equivalent extractor will be used unpack and run it.

3. Latest Binaries: This is the latest build of OBS VCE, please extract it in a folder where you can track versioning, i.e. in a desktop folder with the date of the build:

2016-06-12 [32bit] [64bit] Fix possible stack corruption in 32bit build (or atleast try to :P). (Re-upload)
2015-12-12: [32bit] [64bit] : Update to v0.657b+ JC3 fix mostly.
Or generated HTML with most packages.

Running and configuring:

1. After extracting, run the OBS.exe from that location and open up the Encoding Tab in settings. check VCE instead of x264, then below, have OpenCL to NV12 unchecked
2. In the video tab, Once a downscale and fps is decided (see at the top for maximum resolutions), ensure that the proper GPU is selected from the dropdown.
3. Next, go to the AMD VCE settings tab and check "use Custom settings", Check the preset selector (speed,Balanced,quality) at the upper-right.
4. there are two more options to be changed:
IDR and GOP. IDR will usually be set to 2 times fps (30fps=60IDR) for streaming. you can also set it to 0 which will calculate this for you. -1 disables IDR completely (not common)
GOP will be something to play with but needs to be a multiple of the FPS, this will aid with lagging recording at lower settings. Below is an example based on 30fps recording:
GOP 15, 30, or 60 (the higher, the better compression/quality but more use on the GPU)

Streaming:
With hardware decoders such as VCE, NVENC and QuickSync, an additional 200-500 kbitrate will need to be added to look closer to x264 at the same resolution. This means that 720@30 instead of 2500 bitrate max, VCE will need 3000 bitrate to look the same as x264.

Local Recording Maximum bitrate chart:
// - 10000 bitrate for 720p and frame rate less than or equal to 30 FPS
// - 20000 bitrate for 720p and frame rate less than or equal to 60 FPS
// - 20000 bitrate for 1080p and frame rate less than or equal to 30 FPS
// - 50000 bitrate for 1080p and frame rate less than or equal to 60 FPS


Troubleshooting:

Since OVE no longer works with 15.7 AMD drivers, make sure that "Use AMD AMF instead of OVE" is checked from the encoder tab of OBS. Unchecking can cause "Failed to Initialize" error. I'm leaving OVE in for now for those who may prefer it, though it makes a mess of the settings tab ;)

If Multiple GPUs, select the proper AMD GPU in the video tab. Note that switchable graphics (Intel+AMD) does not work with OBS, this is something with the design of switchable graphics that is flawed.

(Making another thread just-in-case some miss this.)

I've implemented some support for AMD VCE. Probably all kinds of broken and memory leaky, but atleast something to build on :P
So...test it and break it.

Release 32bit binaries: https://dl.dropboxusercontent.com/u/235773/obs-vce.7z

Thank you again, I replied to you in my original thread!!!! You can look there too but since you made a dedicated thread I'll post what I've encountered here too.

First off CPU usage is minimal, so that's awesome! Thank you! I feel the same as when I am recording with Bandicam I can't notice any lag. However two issues I've encountered are a very thin green line at the bottom of my captures, and the second is severe frame tearing. This is the first time I've ever encountered this issue. When I just use OBS or Bandicam I don't get this issue. Here is a video to show you.

Jackun, were you wanting this to get merged in? I assume you don't want to keep it as a fork...

It would probably be good for you to join the #obs-dev IRC channel to be in communication with the other devs. I think there were a couple other people already working on VCE, though I can't remember.

Might be that input buffers are updated while encoder is still doing its thing.
About green line, what resolution are you recording at? VCE (like most h264 encoders probably) needs the resolution to be multiples of 16 or so. Video bitstream (or is in container?) has the original input resolution and player should crop to that (if i'm not mistaken). But we take anything and just pad it out so where there is zero bytes it shows up green in YUV colorspace.

There is an issue with 64bit build. Have to check if it is a issue with 14.4 beta drivers, but for some reason clCreateContext crashes with invalid memory access with device id from openvideo.dll. Then again, my OpenEncodeVFW works with 64bit virtualdub (device id address is lower though)

So far it has been running smooth, i take that CBR isnt possible/you didnt bother with it yet and bitrate is also locked at 2000000?

CBR should be supported (as long as i didn't forget to set any settings :P)
Here, so CBR -> CBR, CRF -> Fixed QP and nothing sets VBR.

Hm, OBS is pretty conservative with requesting key frames? All is just bunch of P frames so seeking is so "fast" heh.

mh i was just asking because with a bitrate set to 1700 (just testing around) it spiked up to 47000kbps with and without cbr checked, the logfile also reports that the bitrate is set to 2000000.

that dll crashes my OBS when I try to get into the encoding settings :)
edit: hmm, now it crashes everytime...
if you want the crashdump, message me, guess I would have to reboot to check if that fixes it for the moment. did a short test yesterday and one earlier today without problems.

Okay that changed a bit. :)
Rate control method is now 3 and it kinda sticks to 2000kbps which i set it to, on no/low motion it still drops to 100kbps and on sudden changes it sometimes shoots up to 10000kbps+, seems really unstable in that regard, pretty much vbr or x264s cbr without padding enabled.

Well, there's a peak rate variable. New version sets it to the bitrate.
It also has 8 input buffers now and for some reason first frame's top half is green.
Getting any duplicate frames? I get some with BF4 randomly.

E: Quick test at 1500Kbps, ffdshow OSD 'input bitrate' shows ~1500 - 1520Kbps

yup with this one it sticks to the bitrate way more stable and similar to "normal" x264 cbr.

edit: whoops didnt see the question, 0.14% duplicated frames, though i dont have any current game that eats cpu/gpu alive to test with.

I'm capturing at 1920 X 1080, standard HD. I'm using the 14.4 drivers but they are release drivers not beta but who knows still could be a driver issue? I have an R9 200x, or is it 220x? I'm using the 32bit version but running on Windows 7 64bit OS don't know if that should be related to the issue.

does the same happen if you downscale to 720p? Jack0r told me in the irc he also had issues with it and he tested 1080p.

Also, i wonder what causes this but currently its not useable for twitch as twitch doesnt accept the cbr behaviour, my guess is since the bitrate starts out really low and climbs up slowly it thinks its vbr and thus gives you only the acceptable flag. Something that also should be sorted out i guess since people will ask about that.

shaNker if you mean tearing then download it again. Should have less now (ok, now >_< ). Bandicam has AMD APP support, right? Does Bandicam's CBR keep its bitrate somewhat stable?

VCE seems to ignore some settings like peak bitrate (resets to bitrate) and VBV buffer size sits at 10Mbps. CBR doesn't want to hard limit to bitrate.
Also my R9 290 takes mysterious control method 5. Maybe Media SDK 1.1 has more info.

Hmm, a reboot did not help either, no matter what, it crashes when I try to check the Encoding Settings. Tried resetting OBS to default settings, etc.

This crash appears to have occured in the 'd:\obs-vce\obsvce.dll' module.

Hmm, a reboot did not help either, no matter what, it crashes when I try to check the Encoding Settings. Tried resetting OBS to default settings, etc.

Get the newer version and upload the dump file. I take it you have supported hardware? :D

Tearing... brainfarting with the RequestBuffers() part. OBS keeps passing old "deallocated" buffer back. Current version just remaps now, but seems to have less tearing (but stutters more?)

Ah, yeah that works, I missed that you updated it in the first post. Now the recording also had no tearing or strange images, but I noticed something else:
using 1920x1080 at 60fps and a recorded video for input
CBR active, 5000 bitrate, everything works
VBR active, 5000 bitrate, everything works
CBR/VBR, 50000 bitrate, takes too long to encode no matter what I try
