obs amd amf encoder crash (arch linux)

[DiarrheaMcgee]

if i try to record anything using amf then it freezes for a couple of seconds and crashes

since typing this it now says Starting the output failed. Please check the log for details. Note: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date.

(and outputs [h264_amf @ 0x56401f54bac0] CreateComponent(AMFVideoEncoderVCE_AVC) failed with error 1 error: [StreamFX] Unexpected exception in function '_create': Encoder not found. into the terminal if i open it from the terminal)

The errors are coming from the third party plugin StreamFX, not this encoder plugin.

[DiarrheaMcgee]

how do i use amd amf in (arch) linux then since when i remove streamfx it disapears

[DiarrheaMcgee]

when i set it to custom output and set it to h264 amf then it says: An unspecified error occurred while recording.

Failed to open video codec: Encoder not found

[DiarrheaMcgee]

its fixed turns out the error message was coming from ffmpeg because of a broken driver downgrading to driver version 21.50.2 fixes it for some reason

[DiarrheaMcgee]

as of a few days ago the issue started happening again

[qiuyaoboy]

I executed the ffmpeg to perform transcoding test and got same issue. My system configurations are as follows: GPU: Radeon Pro W6800 AMDGPU Driver verison: 21.50.2/22.10.2 OS: Ubuntu 20.04.4

[qiuyaoboy]

After downgrading my GPU driver to 21.40.2, downgrading AMF to 1.4.23, recompiling ffmpeg v4.4.1, everything was back to normal.

[DiarrheaMcgee]

that worked for me too (although i used vulkan-amdgpu-pro v21.30_1290604-1)
