Android NDK camera support
* Add native camera video backend for Android
* In the event of a "No buffer available error" wait for the appropriate callback and retry
* Fix stale context when creating a new AndroidCameraCapture
* Add property handling
VideoCapture/DSHOW : Allow to set CAP_PROP_CONVERT_RGB before FOURCC/FPS/CHANNEL/WIDTH/HEIGHT.
* 🐛 cap_dshow : Allow to set CAP_PROP_CONVERT_RGB before FOURCC/FPS/CHANNEL
* 🐛 cap_dshow : fix g_VI.setConvertRGB not being called with correct boolean value on first property set.
* ✅ cap_dshow : Test CAP_PROP_CONVERT_RGB persistence
* 🚨 Fix cast from bool to double
* 🚨 Fix trailing whitespace
add video capture parameters
* add parameters
* videoio: revert unnecessary massive changes
* videoio: support capture parameters in backends API
- add tests
- FFmpeg backend sample code
- StaticBackend API is done
- support through PluginBackend API will be added later

- migrate GStreamer backed
- migrate FFmpeg backend (with switch on legacy API)
- cv_videoio_capture_retrieve_cb_t uses Mat type instead of number of channels
Add CV_16UC1/GRAY16_LE support to GStreamer backend for VideoWriter
* videoio(backend): add Writer_open_with_params to plugin API
This will allow arbitrary parameters to be passed to plugin backends
* videoio(gstreamer): add GRAY16_LE/CV_16UC1 writing support to GStreamer
This introduces a new property VIDEOWRITER_PROP_DEPTH, which defaults to
CV_8U, but for GStreamer can be set to CV_16U.
Also, fix another test to not fail if plugin isn't found, copying logic
from the read_write test.
* videoio(plugin): fix handling plugins with previous API level
* videoio: coding style
* fix warning
Enable frame timestamp tests for MSMF
Add functional test for camera live timestamps
Remove trailing whitespace
Add timestamp test to all functional tests. Protect div by 0
Add Timestamps to MSMF Video Capture by index
- Suppressed FFMPEG + h264, h265 as it does not pass tests with CI configuration.
- Suppressed MediaFoundation backend as it always returns zero for now.
uEye are cameras from IDS, c.f. https://en.ids-imaging.com/
Supports driver version 4.94 and up currently, since the event system was overhauled there.
Supports setting/getting the properties: fps,width,height
* add HEVC(H.265) codec to iOS,Mac VideoWriter
* Update cap_avfoundation_mac.mm
add CV_FOURCC('h','v','c','1') for HEVC codec
* Update cap_avfoundation.mm
add CV_FOURCC('h','v','c','1') for HEVC codec
* feat: add availability check for HEVC codec on iOS and OS X

A running GMainLoop processes many events on the GLib/GStreamer
world. While some things may work without it, many others wont.
Examples of these are signals, timers and many other source
events. The problem becomes more concerning by the fact that
some GStreamer elements rely on signals to work.
This commit allows the user to specify an OpenCV option to
start a main loop, if needed. Since the loop blocks, this is
done in a separate thread.
