Detailed Description

struct vb2_buffer - represents a video buffer : struct v4l2_buffer associated with this buffer; can be read by the driver and relevant entries can be changed by the driver in case of CAPTURE types (such as timestamp) : struct v4l2_planes associated with this buffer; can be read by the driver and relevant entries can be changed by the driver in case of CAPTURE types (such as bytesused); NOTE that even for single-planar types, the v4l2_planes[0] struct should be used instead of v4l2_buf for filling bytesused - drivers should use the vb2_set_plane_payload() function for that : the queue to which this driver belongs : number of planes in the buffer on an internal driver queue : current buffer state; do not change : entry on the queued buffers list, which holds all buffers queued from userspace : entry on the list that stores all buffers ready to be dequeued to userspace : private per-plane information; do not change
