Following entries have been dropped since they are supported: - Implement GstElement::request-new-pad (multi stream) commit 53a0d80af0f9 ("gstreamer: Added virtual functions needed to support request pads") - Add framerate control - Add framerate negotiation support commit ccfe0a1af77c ("gstreamer: Provide framerate support for libcamerasrc") - Add colorimetry support commit fc9783acc608 ("gstreamer: Provide colorimetry <> ColorSpace mappings") - Use unique names to select the camera devices commit 2c93810ec1f1 ("gst: libcamerasrc: Add camera-name property") (The property that is set here is fed into CameraManager::get() eventually, ensuring we can select the camera devices by unique IDs.) - Add GstVideoMeta support (strides and offsets) commit 848a3017b8ee ("gstreamer: Add GstVideoMeta support") At the same time, append the buffer importation support entry to mention the potential usage of memory:DMAbuf, that landed in gstreamer-1.26.
