Lumian 630 returns different source dimension than was requested.
Steps:
1. Compile and run declarative-camera example from multimedia
2. Change between landscape and portrait mode
Expected: Aspect ratio for camera preview is kept.
Actual: Aspect ratio is different
qwinrtcameravideorenderercontrol.cpp
void blit(ID3D11Texture2D *texture)
{
HRESULT hr;
D3D11_TEXTURE2D_DESC desc;
texture->GetDesc(&desc);
if (!m_videoEnumerator) {
D3D11_VIDEO_PROCESSOR_CONTENT_DESC videoProcessorDesc = {
D3D11_VIDEO_FRAME_FORMAT_PROGRESSIVE,
{ 0 }, desc.Width, desc.Height,
{ 0 }, desc.Width, desc.Height,
D3D11_VIDEO_USAGE_PLAYBACK_NORMAL
};
hr = m_videoDevice->CreateVideoProcessorEnumerator(&videoProcessorDesc, &m_videoEnumerator);
RETURN_VOID_IF_FAILED("Failed to create video enumerator");
}
...
desc.Width == 800 and desc.Height == 480 but qt backend requested the sample size to be 640x480.
