Can not use Intel QSV encoders to encode recorded videos

[ysooqe]

I was trying to use a different codec than the default H.264, namely the codecs h264_qsv or hevc_qsv. Unfortunately, this does not work. The following output is given, when trying to record this way:

[PageRecord::StartPage] Started page.
[GLInjectInput::InputThread] Input thread started.
[SSRVideoStreamReader::Init] Created video stream reader.
[PageRecord::StartOutput] Starting output ...

[BaseEncoder::Init] Error: Can't open codec!
[PageRecord::StartOutput] Error: Something went wrong during initialization.

Using hardware accelerated encoding with QSV in other applications (like Handbrake) works, so I do not think its a problem of missing drivers.

Trying to research this issue, I stumbled upon the following: https://trac.ffmpeg.org/ticket/7649#comment:4

This looks like a similar issue. The recommended solution is to manually specify the QSV device, using the paramter qsv_device. Unfortunately, specifying custom ffmpeg parameters does not seem possible using SSR. What could be done to work around that or solve the issue?

I am not a developer so I hope the information I provided is sufficient to understand the issue. If more information is needed, I am happy to provide it.

Same issue here. Looking to use the hevc_qsv codec with SSR v0.4.4 on Linux Mint 21.3, but I get the same "Can't open codec" error when I attempt to start a recording. Adding "-qsv_device" to the Custom options field doesn't resolve this issue either. Any assistance would be much appreciated.
