Question / Help OBS MP AMD VCE settings

[John Z]

Hello!

I love the new OBS MP and the feature that I can use my graphics card instead of CPU. It allows me to stream quite nicely.

Altho the problem stands in the right settings. I use my encoder "x264 AMD VCE" instead of "x264".

Now the quality is somewhat ok-ish but slightly pixel-ish. Where how how could I find the right settings and my Rate control is to set "CBR" but the bitrate goes up to 7000 sometimes even. Its not streamable like that.


Setup:

CPU: FX 6300
RAM: 6gb ddr3
GPU: R9 270x
OP: Windows 10 pro (latest build and up-to-date updates)

Unfortunately, AMD VCE will just ignore your CBR settings and will use VBR, making it absolutely useless for streaming because there's no way to get it to stay at a bitrate that's watchable/won't get you banned from Twitch for exceeding the 3500 cap non partners have.

I have an AMD CPU myself, and VCE seems like the perfect option for me to stream. I don't know if it's the encoder itself or a bug in OBS MP, but I've yet to find a solution to making streaming with VCE viable.

I too tried streaming with the AMD VCE H.264 Encoder selected (with "enforce streaming service settings" checked, Keyframe 2, CBR, bitrate 1750 and Low Latency off).

The problem that arises is that instead streaming in 30 FPS as selected under "Video" my viewers told me that the stream is actually showing 10 FPS only. I tried setting keyframes to 0 but that resulted in my audience being confronted with a black screen (while audio was fine).

So my question is: Is there a way to stream with the AMD encoder selected to Twitch in 30 FPS?

Bump.

CPU: FX 8350
GPU: AMD HD 7950
OP: Win10

I can't figure out how the "QP"-thing works!

Just to reiterate, streaming with VCE is not recommended as it does not support CBR.

@G1nux QP should work like CRF, lower values generate higher quality.
