2022-08-24gstreamer: Add support for additional RGB formatsLaurent Pinchart
libcamerasrc only supports three RGB formats. Adding the other RGB formats supported by libcamera is trivial, do so.

2022-07-04gstreamer: Use gst_task_resume() when availableLaurent Pinchart
The gst_libcamera_resume_task() helper is an implementation of the gst_task_resume() function that predates its addition to GStreamer. Use gst_task_resume() when available, and rename gst_libcamera_resume_task() to gst_task_resume() to support older GStreamer versions.

Existing pipeline handlers already support planar YUV formats. Extend the gstreamer format map to incorporate them. While here, split the formats into distinct groups.

2021-08-26gstreamer: Fix usage of default size for fixationNicolas Dufresne
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.

2021-08-26gstreamer: Fix concurrent access issues to CameraManagerNicolas Dufresne
It's not allowed to have multiple instances of CameraManager. This requirement is not easy for GStreamer were the device monitor and the camerasrc, or two camerasrc instances don't usually have any interaction between each other. Fix this by implementing a minimalist singleton around CameraManager constructor and start()/stop() operations.

2020-03-07gst: Add utility to convert StreamFormats to GstCapsNicolas Dufresne
This transforms the basic information found in StreamFormats to GstCaps. This can be handy to reply to early caps query or inside a device provider. Note that we ignored generated range as they are harmful to caps negotiation. We also don't simplify the caps for readability reasons, so some of the discrete value may be included in a range.
