2020-10-12libcamera, android, cam, gstreamer, qcam, v4l2: Reuse RequestPaul Elder
Allow reuse of the Request object by implementing reuse(). This means the applications now have the responsibility of freeing the Request objects, so make all libcamera users (cam, qcam, v4l2-compat, gstreamer, android) do so.

2020-08-25meson: Remove -Wno-unused-parameterLaurent Pinchart
We build libcamera with -Wno-unused-parameter and this doesn't cause much issue internally. However, it prevents catching unused parameters in inline functions defined in public headers. This can lead to compilation warnings for applications compiled without -Wno-unused-parameter. To catch those issues, remove -Wno-unused-parameter and fix all the related warnings with [[maybe_unused]].

2020-08-14libcamera: request: Make Stream pointer constNiklas Söderlund
The Stream pointer just acts as a key in the Request object. There is no good use-case to modify a stream from a pointer retrieved from the Request, make it const. This allows pipeline handlers to better express that the Stream pointer is retrieved in a Request should just be treated as a key.

2020-05-16libcamera: Move internal headers to include/libcamera/internal/Laurent Pinchart
The libcamera internal headers are located in src/libcamera/include/. The directory is added to the compiler headers search path with a meson include_directories() directive, and internal headers are included with (e.g. for the internal semaphore.h header) #include "semaphore.h" All was well, until libcxx decided to implement the C++20 synchronization library. The __threading_support header gained a #include <semaphore.h> to include the pthread's semaphore support. As include_directories() adds src/libcamera/include/ to the compiler search path with -I, the internal semaphore.h is included instead of the pthread version. Needless to say, the compiler isn't happy. Three options have been considered to fix this issue: - Use -iquote instead of -I. The -iquote option instructs gcc to only consider the header search path for headers included with the "" version. Meson unfortunately doesn't support this option. - Rename the internal semaphore.h header. This was deemed to be the beginning of a long whack-a-mole game, where namespace clashes with system libraries would appear over time (possibly dependent on particular system configurations) and would need to be constantly fixed. - Move the internal headers to another directory to create a unique namespace through path components. This causes lots of churn in all the existing source files through the all project. The first option would be best, but isn't available to us due to missing support in meson. Even if -iquote support was added, we would need to fix the problem before a new version of meson containing the required support would be released. The third option is thus the only practical solution available. Bite the bullet, and do it, moving headers to include/libcamera/internal/.

2020-03-06test: Extract BufferSource class out of camera tests to libtestNiklas Söderlund
The BufferSource class can be used by other tests other then the camera buffer importer test, move it to libtest. The only changes to BufferSource is for it to be allowed to be split in a header and source file. This change makes it necessary for libtest to have access to internal libcamera headers. As the internal headers already are accessible to all test cases this does not increase the exposure of libcamera internals to the test cases.

2020-01-12test: camera: buffer_import: Update to FrameBuffer restrictionsNiklas Söderlund
With the FrameBuffer interface the V4L2 buffer indexes are not visible outside the V4L2VideoDevice so it's not possible to to test that the expected indexes are used when using external buffers (allocated directly from a V4L2 video device) with a Camera. Rewrite the test to this limitation. The idea of the test stays the same, test that buffers allocated from a V4L2 video device (vivid) can be imported and used on a Camera (vimc). As an added bonus the rewrite makes use of the FrameBuffer interface for the allocation of buffers at the source (vivid) and imports them to the Camera which still uses the Buffer interface internally.

2020-01-12libcamera: buffer: Switch from Plane to FrameBuffer::PlaneNiklas Söderlund
It is not libcamera's responsibility to handle memory mappings. Switch from the soon to be removed Plane class which deals with memory mappings to FrameBuffer::Plane which just describes it. This makes the transition to the full FrameBuffer easier. As the full FrameBuffer interface has not yet spread to all parts of libcamera core it is hard to create efficient caching of memory mappings in the qcam application. This will be fixed in a later patch, for now the dmabuf is mapped and unmapped each time it is seen by the application.

2019-08-11libcamera: pipeline: vimc: Switch to using the RGB/YUV Capture video nodeNiklas Söderlund
Linux commit 85ab1aa1fac17bcd ("media: vimc: deb: fix default sink bayer format") which is part of v5.2 changes the default media bus format for the debayer subdevices. This leads to a -EPIPE error when trying to use the raw capture video device nodes. Fix this by moving the vimc pipeline to use the RGB/YUV Capture capture video node. As a consequence of this change the scaler in the vimc pipeline is used and a hard coded upscale of 3 is present in the video pipeline. This limits the sizes exposed and accepted by libcamera to multiples of 3. Update the buffer import test case to match this new format constraint by setting the resolution to 1920x1080, a resolution which works with both vimc and vivid. With this new resolution the buffer import test takes a bit more time to complete 60 buffers and it's runtime also needs to be increased. The raw capture video node still needs to be handled by the pipeline as its format needs to be updated to allow the pipeline format validation to pass.

The FrameSink::cleanup() call checks if video_ is set before cleaning up and then deleting the object. If the cleanup() call is called twice for any reason, this will encounter a use-after-free as the video_ pointer is not cleared after deletion. Whilst cleanup() is not currently called twice consecutively, to prevent errors in the future, make it explicit that the object has been deleted by clearing the stale pointer.
