Detailed Description

struct vb2_queue - a videobuf queue

: queue type (see V4L2_BUF_TYPE_* in linux/videodev2.h : supported io methods (see vb2_io_modes enum) : additional io flags (see vb2_fileio_flags enum) : pointer to a mutex that protects the vb2_queue struct. The driver can set this to a mutex to let the v4l2 core serialize the queuing ioctls. If the driver wants to handle locking itself, then this should be set to NULL. This lock is not used by the videobuf2 core API. : The filehandle that 'owns' the buffers, i.e. the filehandle that called reqbufs, create_buffers or started fileio. This field is not used by the videobuf2 core API, but it allows drivers to easily associate an owner filehandle with the queue. : driver-specific callbacks : memory allocator specific callbacks : driver private data : size of the driver-specific buffer structure; "0" indicates the driver doesn't want to use a custom buffer structure type, so sizeof(struct vb2_buffer) will is used

: current memory type used : videobuf buffer structures : number of allocated/used buffers : list of buffers currently queued from userspace : number of buffers owned by the driver : list of buffers ready to be dequeued to userspace : lock to protect done_list list : waitqueue for processes waiting for buffers ready to be dequeued : memory type/allocator-specific contexts for each plane : current streaming state : file io emulator internal data, used only if emulator is active
