Doesn't work VaapiPostProcessScaler
VaapiPostProcessScaler doesn't work. It returns SharedPtr < VideoFrame > with zeros in crop.width and crop.height. I tested it on the vpp test and my application. I use DRM as display. But all tests are passed.
I use Ubuntu 16.04. The latest libva, libyami and intel-vaapi-driver.
could you share you command line and try our yamivpp application https://github.com/01org/libyami-utils/blob/master/tests/vpp.cpp like "yamivpp
I just run vpp/unittest. Also I added this line std::cout << std::to_string(dest->crop.width) << " " << std::to_string(dest->crop.height) << std::endl; to VppDeinterlace function in vaapipostprocess_scaler_unittest.cpp after this line EXPECT_EQ(YAMI_SUCCESS, scaler.process(src, dest));
And I get only zeros. Is it normal?
I ran our yamivpp application. And it works.
Yes, it's defined feature. If crop is zero, It will scale to the entire surface. We have src crop and dest crop. src crop means you only need a sub rect on the source, dest crop means you only need scale src to the sub rect of dest.
ok, thank you for the answer.
Also quick question I tried to test YAMI_FOURCC_Y800 format for scaling but I get the error: "the requested function is not implemented". Do you plan to support it? And where can I get the list of supported formats for scaling?
It's the error returned by libva. we depend on libva to do vpp.
Hi @xhaihao, Can we query csc format in libva?
HI @AlexanderKomarov Could you share us the usecase? Why you need Y800 scaling?
thanks
vaQuerySurfaceAttributes can return the supported surface attribute list for a given config, including pixel formats
@xuguangxin @xhaihao thanks for the answers.
We try to use Intel GPU for decoding/encoding JPEG from camera, scaling and transforming images. We use gray image in our system. Our system does face detection and face recognition.
@xuguangxin @xhaihao maybe is there some sense to add the issue of adding support Y800 for vpp in libva project?
