* Fix GetFrameRateList checks and memory leakNate Weibley2019-07-051-2/+4
| | | | | | | | | | GetFrameRateList passes an unmanaged pointer to the caller which must be manually freed with CoTaskMemFree. Additionally the Chromium project notes that some drivers cause quirky return values which we would not catch without stricter checks.

* DirectShow: Fix crash when camera is being destroyedVal Doroshchuk2019-02-061-4/+1
| | | | | | | | | | | | If a camera is going to be destroyed, a service plugin releases media service, (which releases ds camera session) and might call CoUninitialize. This leads to a crash when DirectShowSampleGrabber is destroyed after releasing the camera. Added a fix to release the sample grabber together with camera session.

| | | | | | | | | | | | | | | | | | | | Added camera image encoder control that 1. applies image encoder settings (resolution and codec) used to capture images 2. returns supported image codecs from QImageWriter::supportedImageFormats 3. returns supported resolutions Since DirectShow camera session uses QImage based on QVideoFrame image encoder control returns viewfinder supported resolutions. Not available if camera is not loaded. Setting resolution via encoder control causes viewfinder resolution to be ignored.

| | | | | | | | | | | | | | | | | | | If being used camera has been disconnected, state and status will remain like it is still active. Also no events are sent. Previously to fix this the camera needed to be unloaded and loaded again manually. IMediaEvent provides an ability to catch device removal notification with EC_DEVICE_LOST event. Since ISampleGrabber is used to get buffers. Added a fix to check if no buffers received for some time afterwards check for EC_DEVICE_LOST event. In case if the device is lost, the camera should be unloaded.

* DirectShow: Emit an error if QCamera::start() failsVal Doroshchuk2018-03-211-13/+25
| | | | | | | | | | | | | | | | | | | If a camera is not started successfully, then an error() should be emitted. After an error the camera's state will be QCamera::UnloadedState and status will be QCamera::UnloadedStatus. The error signal is handled when the camera is unable to set following states: QCamera::UnloadedState, QCamera::LoadedState or QCamera::LoadingState. Thus additionally to QCamera::start() an error can be emitted even when QCamera::load(), QCamera::unload(), or QCamera::stop() is called.

When MDI subwindows are overlapping bottom window with QImage::Format_RGB32 requires 0xffRRGGBB. If "not used byte" is not 0xFF rendering will not be correct (0x00 produces empty image). Changed samples to ARGB32 to provide alpha channel, which is 0xFF in most cases. If alpha channel is not set to 0xFF, the bottom window will still be rendered incorrectly.
