2021-09-24libcamera: Standardize URLs to git repositoriesLaurent Pinchart
When the libcamera project was started, we had no public git tree hosted on git.libcamera.org. The problem has been addressed a while ago, and the git.linuxtv.org libcamera repository is now a mirror of the main git tree. The mirror is useful to benefit from the linuxtv.org automated compile tests, but it can also confuse users who don't know where the official version is. To try and clarify this, use the git.libcamera.org URL consistently through the project. This doesn't void the validatity of the linuxtv.org repository which will continue to mirror the libcamera.org repository.

2021-09-24android: camera_device: Return unique_ptr from createFrameBufferLaurent Pinchart
Returning a non-managed pointer can cause leaks. Use a unique_ptr<> instead to avoid possible future issues. The std::move() for the planes argument to the FrameBuffer constructor is dropped as it's misleading. FrameBuffer has no constructor that takes an rvalue reference to planes, so the vector was copied despite the move. This only clarifies the intent, no functional change is introduced.

2021-09-23test: gstreamer: Simplify elements' ownershipsVedant Paranjape
In gstreamer, when elements are created, usually a floating [1] reference is returned which simply means, there is no ownership transfer (yet). Once can simply check for NULL and return through an error path, without bothering to clean up. Hence, g_autoptr is not much of help here. If the NULL checks have been passed successfully, elements are ready to use. However, we must claim ownership/reference it before using them via g_object_ref_sink(). This patch build upon this principle and removes the g_autoptr from gstreamer test base class (gstreamer_test.cpp) whereever necessary to tide up the code.

When creating a DRM frame buffer, the dmabufs for the planes are imported as GEM objects. For multi-planar formats, all planes may use the same dmabuf, which results in multiple imports. This doesn't cause any issue at import time, as DRM detects this situation and returns the same GEM object. However, when destroying the frame buffer, the same GEM object ends up being closed multiple times, which generates an error. Fix this by avoiding multiple imports of the same dmabuf for the same frame buffer.

2021-09-07cam: drm: Support per-plane stride valuesLaurent Pinchart
The stride is not always identical for all planes for multi-planar formats. Semi-planar YUV formats without horizontal subsampling often have a chroma stride equal to twice the luma stride, and tri-planar YUV formats with a 1/2 horizontal subsampling often have a chroma stride equal to half the luma stride. This isn't correctly taken into account when creating a DRM frame buffer, as the same stride is set for all planes. libcamera doesn't report per-plane stride values yet, but uses chroma strides that match the above description for all currently supported platforms. Calculation the chrome strides appropriately in the KMSSink class, and pass them to DRM::createFrameBuffer().

2021-09-07cam: Add Image classLaurent Pinchart
The new Image class represents a multi-planar image with direct access to pixel data. It currently duplicates the function of the MappedFrameBuffer class which is internal to libcamera, and will serve as a design playground to improve the API until it is considered ready to be made part of the libcamera public API.

2021-09-07android: jpeg: Support multi-planar buffersLaurent Pinchart
The JPEG post-processor uses MappedFrameBuffer to access pixel data, but only uses data from the first plane. Pass the vector of planes to the encode() function to correctly handle multi-planar formats (currently limited to NV12).
