I am using screen capture module along with sample_encode module to capture my desktop image and encode it into h264 format. I am running this application on a Windows8 desktop machine and on a windows8 Microsoft surface device and it works fine. Now I want to add the support of screen rotation feature for Microsoft Surface device.
At present when surface device is rotated at 90 degree then I get the captured output frame un-oriented but image is rotated inside. E.g. if original desktop resolution is 1920x1080 and it is rotated by 90 degree, then capture module delivers raw output frame of 1920x1080 resolution in which desktop image is rotated inside.
My objective in this case is to get a final output frame with 1080x1920 resolution (height width swapped )so that desktop image still looks un-rotated even though device is rotated.
I checked in media sdk and found that there is a rotation plugin which supports only 180 degree rotation and that too for jpeg decoding only. So is there any module/lib in media sdk which supports image rotation (by 90, 180 & 270 degree) during screen capturing or h264 encoding, or h264 decoding?
My environment details are as following:
IMSDK version: 22.214.171.1249
Sample decode version: 126.96.36.199
OS: Windows 8.1
Graphics Card: Intel(R) HD Graphics 4400 with driver version 10.18.14.4294
I think you should try Intel® Media SDK 2016 , after installation you can find following in mediasdk_release_notes.pdf
Page 2 -
mfxstructures.h: MFX_EXTBUFF_VPP_ROTATION and corresponding
mfxExtVPPRotation extended buffer structure added to support
rotation in VPP
Page 3 -
Added rotation filter support for MFX_IMPL_VIA_D3D11 path with
90,180,270 angles support and progressive content only.
Hope it helpful.
I am using d3d11 to do Rotation using mfxExtVPPRotation for progressive NV12 content
intel media sdk version using is 188.8.131.521.
But MFXVideoVPP_Query returns error MFX_ERR_UNSUPPORTED.
tracer log Attached.please help me to resolve this problem
Os version is Windows 8.1 and intel graphics card present
