2023-01-16lib/video-source: Add video_source_import_buffersDaniel Scally
We need to be able to place encoded data into the sink device's bufs. To facilitate that add a video_source operation that allows the source to import buffers from the sink. Add a .import_buffers() callback so that the libcamera-source can access a sink's buffers.

2023-01-16lib: Add video_source_type enumerationDaniel Scally
Add an enum to struct video_source that details the type of source we're dealing with. This will be used to make decisions about buffer allocation and handling in a more explicit way. Use the video_source_type associated with a video_source to decide on the appropriate allocation function and buffer handler at stream on time. This is a more explicit method than relying on the presence of the .alloc_buffers op and allows more flexibility.

2019-02-06video-source: add video_source_set_frame_ratePaul Elder
We would like to be able to set the frame rate for video sources. This patch adds a set_frame_rate op for video sources, along with a wrapper to call video sources' set_frame_rate functions.

2018-06-12Split UVC gadget into a library and test applicationLaurent Pinchart
Split the project into a UVC gadget library and a test application. To avoid rolling out a custom build system, switch to CMake. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
