Getting VA_STATUS_ERROR_UNSUPPORTED_RT_FORMAT

[shakeeb80]

Does any one know what this error message means. I am getting this error after calling vaCreateSurfaces(). I am using libva 2.4.0 and iHD driver. The function is trying to allocate NV12

@shakeeb80 could you print the parameter when you call vaCreateSurfaces()?

following is the code , it is taken from gstreamer media sdk which is actually failing ( https://github.com/intel/gstreamer-media-SDK/blob/0c25a4c6b724a03676cdf3dc14d85ca74f22ba5c/gst-libs/mfx/gstmfxtask.c )
It is failing on line number 157. The weird things is that it only happens when I link the gstreamer elements using shared objects. If I statically link it works.

VASurfaceAttrib attrib;
VASurfaceID surfaces[12];

attrib.type = VASurfaceAttribPixelFormat;
attrib.flags = VA_SURFACE_ATTRIB_SETTABLE;
attrib.value.type = VAGenericValueTypeInteger;
attrib.value.value.i = VA_FOURCC_NV12;

GST_MFX_DISPLAY_LOCK(task->display);
auto status = vaCreateSurfaces(
GST_MFX_DISPLAY_VADISPLAY(task->display),
VA_RT_FORMAT_YUV420,
1920,
1088,
surfaces,
12,
&attrib,
1);

GST_MFX_DISPLAY_UNLOCK(task->display);

it is interesting, could some one provide help on this issue?

with "statically linked" do you mean libva?

That error comes up from the driver, which cannot be statically linked. You should debug the callback in the driver.

Regarding gstreamer-media-SDK neither @sreerenjb nor myself were the maintainers :)

Can you provide the reproduce step for me? I will check on it.
