intel-vpl-gpu-rt with MFX_ENABLE_SVC_VIDEO_ENCODE

[bernardt]

Hello,

I’m working with Buildroot and trying to compile intel-vpl-gpu-rt 25.3.4. I pinned all the dependencies as specified in the release notes (see below).

With the default options enabled, everything compiles without any issues.

However, when I enable the MFX_ENABLE_SVC_VIDEO_ENCODE option, things start to break.

The compilation fails with several errors:

• Undefined symbols

• Instantiation of an abstract class

• Methods declared but not defined (linker errors)

These errors all point to two specific classes — ImplementationSvc and TaskManagerSvc — located in:

_studio/mfx_lib/encode_hw/h264/include/mfx_h264_encode_hw_utils.h

I tried building different versions of the library.
I also tried enabling all the options in mfx_features.h.in, thinking that some of them might be required as dependencies.

In the end, I was still unable to get the code to compile.

Is the MFX_ENABLE_SVC_VIDEO_ENCODE option still under development?
Am I missing something?

Thanks in advance for any help!

PS1: i didn't see any github discussion tab on the github page, it is why i came here for a simple compilation error.

PS2: i can provide the explicit error if needed.
