2024-07-25gstreamer: allocator: Ensure camera manager stay aliveNicolas Dufresne
Without the camera manager, it is not possible to cleanly delete the FrameBufferAllocator object. Keep the camera manager alive until all the memory object have been released. A shared_ptr to the CameraManager is introduced which is itself stored as a plain pointer and allocated and released explicitly. When more than one C++ member is required, this can be refactored to use a new C++ class, but the struct _GstLibcameraAllocator is allocated and freed by glib, so it does not have automatic destruction presently.

2024-06-26test: gstreamer: Include missing sanitizer/asan_interface.h headerLaurent Pinchart
The GStreamer tests define a __asan_default_options() function to influence the behaviour of ASan. The function is declared in sanitizer/asan_interface.h, but we don't include the header. This will cause missing declaration warnings when we enable the -Wmissing-declarations option. Include the header to fix the issue. It can't be done unconditionally as not all toolchains provide ASan, so check for its availability at configuration time.

2024-05-13test: gstreamer: Simplify single stream testNicolas Dufresne
The single stream test for the GStreamer component has a simple pipeline construction using only a fakesink. The implementation currently supports connecting to a more complex stream construction defined by the streamDescription, but this is over engineered for the simple need to start a stream to capture and discard the frames. Convert the use of gst_parse_bin_from_description_full() which uses only a single element 'fakesink' to construct the fakesink directly and link it to the libcamerasrc.

Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it.

2023-12-07test: gstreamer: Remove videoconvert element from pipelineLaurent Pinchart
The GStreamer single stream test uses the following pipeline: libcamerasrc ! videoconvert ! fakesink The videoconvert element isn't useful as the data is thrown away by the fakesink anyway. We can shorten the pipeline to libcamerasrc ! fakesink to save CPU time and to avoid depending on the gstreamer1.0-plugins-base package to run the unit tests. The test could be further simplified by replacing gst_parse_bin_from_description_full() with gst_element_factory_make(), now that we only add one element to the bin. The extra cost incurred by the bin only impacts initialization time, and using a bin will make it easier to add other elements in the future if needed. Keep the bin, and only drop the videoconvert element.

2022-07-24test: gstreamer: Check availability of cameras before runningUmang Jain
Move the logic for checking the availability of cameras from multi_stream_test to gstreamer test base class. Since single_stream_class always assumes that a camera is available on the system (which is not always the case for e.g. RPi in CI/CD environments) it makes sense to have the availability check in the base class. If no cameras are available, the behaviour should be to skip instead of a failure. We currently have 2 tests for gstreamer differing based on number of streams supported by the camera. Hence, the camera availability is checked in conjunction with the number of the streams required by the derived class.

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.

Better way to tackle this issue was disabling forks on the gstreamer side. verify_asan_link_order=0 disables the check on ASan side which checks if ASan was loaded before any other shared objects. Since, gstreamer spawns a child helper process while building the registry, we needed to disable this check.

This patch adds a test to test if single stream using libcamera's gstreamer element works.

This is covered by the suppression file shipped with glib, but it's not clear how to use it automatically. For now, disable leak detection to avoid test failures. - GStreamer spawns a child process to scan plugins. If GStreamer is compiled without ASan (which is likely) but libcamera is, dlopen()ing the libcamera plugin will cause an ASan link order verification failure. Disable the verification child processes to work around the problem. This requires gcc 8 or newer.
