The V4L2 Compatibility layer is returning timestamps for buffers which are incorrectly calculated from the frame metadata. The sec component of the timestamp is correct, but the usec component is out, leaving frame captures reporting non-monotonically increasing timestamps, and incorrect frame rate calculations. Fix the usecs calculation reported by the V4L2 adaptation layer.

We now handle disabling ("pausing") AWB in the same way as AEC/AGC. Instead of letting the pause flag be set so that the code never runs at all, we instead fix the manual settings to the current values (but continue to be called).

Objects are not expected to be connected to the same signal more than once. Doing so likely indicates a bug in the code, and can be highlighted in debug builds with an assert that performs a lookup on the signals_ list. While it is possible to allow the implementation to let objects connect to a specific signal multiple times, there are no expected use cases for this in libcamera and this behaviour is restricted to favour defensive programming by raising an error when this occurs. Remove the support in the test framework which uses multiple Signal connections on the same object, and update the test to use a second Signal.

2022-02-03lc-compliance: Only download gtest subproject as a fallbackJavier Martinez Canillas
Currently, a subproject is used to fetch gtest dependency unconditionally for any Linux distribution besides ChromeOS. But it leads to a regression in distros whose builders are not allowed to download files during build. This change was introduced by commit 0d50a04cc918 ("lc-compliance: Build with gtest in subprojects") and the rationale is that some distros, such as Debian ship libgtest-dev as a static library. And this could be built with a different toolchain than the one used to build libcamera itself. But this seems to be a corner case, usually users will either build both libcamera and all its dependencies using the same toolchain or build it using both the libgtest library and toolchain as provided by the distro. If someone doesn't want for meson to pick up the non-compatible static library provided by the distro, then instead should make sure that their build root does not have the package providing this installed. Let's simplify the logic to find the dependency and just use the built-in support in dependency() function to fallback to a subproject if not found. This covers to common case of attempting to use the gtest provided by the system or pulling from source if not found or is not preferred. To force meson to fallback to the wrap for gtest you can use this command: meson configure -Dforce_fallback_for=gtest and to force fallback for all the dependencies, you can use the following: meson build --wrap-mode=forcefallback Fixes: commit 0d50a04cc918 ("lc-compliance: Build with gtest in subprojects") Reported-by: Eric Curtin <ecurtin@redhat.com> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Hirokazu Honda <hiroh@chromium.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

This change fixes usage of the V4L2 compatibility layer with OpenCV. While at it, attempt to validate the other flags. videobuf2 requires MAP_SHARED and doesn't check other flags, so mimic the same behaviour.

2022-02-01pipeline: raspberrypi: Fix the buffer count calculation for the ISP input streamNaushir Patuck
The ISP input stream currently only allocates a single slot in the V4L2VideoDevice cache as it follows the number of buffers allocated for use. However, this is wrong as the ISP input stream imports buffers from Unicam image stream. As a consequence of this, only one cache slot was used during runtime for the ISP input stream, and if multiple buffers were to be queued simultaneously, the queue operation would return a failure. Fix this by passing the same number of RAW buffers available from the Unicam image stream. Additionally, double this count in the cases where buffers could be allocated externally from the application.

Thus, simply duplicate the checks done by vidioc_qbuf. To match the error checks done by kernel implementation, we'd have to check if dmabuf fd is valid and that the buffer size is large enough.

Building the libcamera Android layer currently makes use of features from meson 0.55. The core libcamera framework in the default configuration without android enabled uses the 'summary' feature available in 0.53, and is the lowest supportable meson version if the Android HAL is excluded. Ubuntu 20.04 LTS currently provides meson 0.53 and represents an acceptable minimum version to support. Platforms utilising the Android component will have full control over their build environment and can ensure that they provide a more recent version of meson. Reduce the supported meson version for the project to 0.53 to facilitate building on more distributions without having to manually update the meson package. Meson will output a warning that features not available in 0.53 are used if the Android HAL is enabled. This is considered as an acceptable middleground to improve the experience on the latest Ubuntu LTS, until 22.04 LTS is released and provides a newer meson version.

The MediaDevice lock is meant to prevent concurrent usage of multiple cameras from the same pipeline handlers. As media devices are acquired by pipeline handlers, we can't have multiple pipeline handlers trying to lock the same media device. The recursive locking detection can thus be moved to the pipeline handler. This simplifies the media device implementation that now implements true lock semantics, and prepares for support of concurrent camera usage.

The initial commit a146cdbf20cb ("readme: Provide build requirements") used tabs for all the dependencies. The first time a line was edited in commit 2de78434ca71 ("meson: Bump required version to 0.47") tabs were not kept. This makes them all consistent.
