2021-08-30libcamera: framebuffer: Add assertion to detect offset is unfilledHirokazu Honda
The offset variable is introduced to FrameBuffer::Plane. In order to detect that the plane is used while the offset is not set, this adds the assertion to FrameBuffer::planes(). It should be removed in the future.

Pipeline managers sets a default value to StreamConfiguration::size. The original fixation code was attempting to use it, but as it was truncating the caps to its first structure it would never actually find a best match. In this patch, instead of truncating, we weight various matches using the product of the width and height delta. We also split delta from ranges apart and prefer fixed size over them as ranges are not reliable. This patch also removes the related todo, as it seems that libcamera core won't go further then providing this default value and won't be sorting the format and size lists.

2021-08-26test: gstreamer: Disable gstreamer registry forksVedant Paranjape
ASan needs to be loaded first before gstreamer is loaded. This was not possible, so verify_asan_link_order was disabled. 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. But with gst_registry_fork_set_enabled() it is possible to disable spawning this child helper process, so this ensures that ASan is loaded before any other shared object is loaded.
