2020-11-07gstreamer: libcamerasrc: Delete configuration before stopping camera managerLaurent Pinchart
When closing the libcamerasrc, the reference to camera is released and the camera manager is stopped. However, the camera configuration still exists at that point, and holds a reference to the camera. This leads to a warning from the device enumerator complaining that the media devices are still in use: [1:53:48.792327560] [408] ERROR DeviceEnumerator device_enumerator.cpp:165 Removing media device /dev/media1 while still in use [1:53:48.792354022] [408] ERROR DeviceEnumerator device_enumerator.cpp:165 Removing media device /dev/media0 while still in use A crash follows when the libcamerasrc is finalized, as deleting the camera configuration will then release the last reference to the camera, which attempts to delete the camera object with deleteLater() without an event dispatcher. Fix it by deleting the camera configuration before stopping the camera manager.

2020-11-07libcamera: v4l2_videodevice: Check plane count when setting formatLaurent Pinchart
When setting (or trying) a format with a multiplanar device, the V4L2VideoDevice::trySetFormatMeta() function iterates over all planes available in the V4L2DeviceFormat structure. The caller is responsible for setting the plane count, and failure to do so properly may result in memory corruption. This can lead to a crash way after the function returns, making the problem difficult to debug. As the issue is caused by a bug in the caller, use an assertion to catch it.

2020-11-07libcamera: v4l2_videodevice: Zero-initialize planes in V4L2DeviceFormatLaurent Pinchart
The V4L2DeviceFormat class doesn't have a default constructor, neither does it specifies default member initializers for the plane-related members. This results in the planes array and planesCount members being uninitialized by default, leading to undefined behaviour if the user of the class doesn't initialize it explicitly. Most users initialize V4L2DeviceFormat instances, but some don't. We could fix them, but that would likely turn into a game of whack-a-mole. As there's no use case for instantiating a large number of V4L2DeviceFormat instances in a performance-critical code path, let's instead add default initializers to avoid future issues. While at it, define a type of the structures containing plane information, and use an std::array.

2020-11-07qcam: viewfinder_gl: Add support for RGB formatsLaurent Pinchart
Add support for 24-bit and 32-bit RGB formats. The fragment samples the texture and reorders the components, using a pattern set through the RGB_PATTERN macro. The pattern stores the shader vec4 element indices (named {r, g, b, a} by convention, for elements 0 to 3) to be extracted from the texture samples, when interpreted by OpenGL as RGBA. Note that, as textures are created with GL_UNSIGNED_BYTE, the RGBA order corresponds to bytes in memory, while the libcamera formats are named based on the components order in a 32-bit word stored in memory in little endian format. An alternative to manual reordering in the shader would be to set the texture swizzling mask. This is however not available in OpenGL ES before version 3.0, which we don't mandate at the moment. Only the BGR888 and RGB888 formats have been tested, with the vimc pipeline handler.
