2022-07-04gstreamer: Pass Stream to RequestWrap::addBuffer()Laurent Pinchart
For symmetry with RequestWrap::removeBuffer(), pass the Stream pointer to addBuffer(). This handles streams at the GstPad level instead of the GstBuffer level, which allows making the GstLibcameraPool API a bit cleaner by removing the gst_libcamera_buffer_get_stream() helper function.

2021-03-12gst: pool: Fix GstBuffer leak on errorNicolas Dufresne
We borrowed a GstBuffer from the pool, if preparing the buffer failed, we need to push it back to avoid leaking it.

2020-10-20gstreamer: Omit extra semicolonsHirokazu Honda
Macros used in gstreamer (e.g. G_DEFINE_TYPE) are functions. The end semicolons with the macros are unnecessary.

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]].

2020-03-07gst: libcamerasrc: Prevent src task deadlock on exhausted buffer poolJakub Adam
Allow GstLibcameraPool to notify the source when a new buffer has become available in a previously exhausted buffer pool. This can be used to resume a src task that got paused because it couldn't acquire a buffer. Without this change the src task will never resume from pause once the pool gets exhausted. To trigger the deadlock (it doesn't happen every time), run: gst-launch-1.0 libcamerasrc ! queue ! glimagesink Signed-off-by: Jakub Adam <jakub.adam@collabora.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

This is needed to track the lifetime of the FrameBufferAllocator in relation to the GstBuffer/GstMemory objects travelling inside GStreamer.
