[Bug]: vaQueryVideoProcPipelineCaps: filter_flags always 0 in struct VAProcPipelineCaps #1843

Closed z0Kng closed 2 months ago

z0Kng commented 3 months ago

Which component impacted?

Video Processing

Is it regression? Good in old configuration?

No, this issue exist a long time

What happened?

Shouldn't it be possible, as described in the documentation, to query the supported filter_flags from the driver with vaQueryVideoProcPipelineCaps?

However, filter_flags is always 0: https://github.com/intel/media-driver/blob/5641059bea7098ab0abd40dc9f3d13f1c7797013/media_driver/linux/common/ddi/media_libva.cpp#L6675

What's the usage scenario when you are seeing the problem?

Others

What impacted?

Its needed for the gstreamer va plugin implementation of interpolation methods, see: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7301

Debug Information

No response

Do you want to contribute a patch to fix the issue?

Hi@z0Kng, Current scaling/iscaling enum value cannot be reported as caps. The value cannot be updated to avoid backward compatible issue. you can use flag definition directly in document documentation instead of call vaQueryVideoProcPipelineCaps(). image

Hi @VincentCheungKokomo thanks for the detailed answer. I had already hardcoded it, I just wanted to check if the hardware supports the different interpolation methods. So is it safe to assume that all hardware supports all interpolation and scaling methods?

Yes, hardware supports all interpolation and scaling methods.
