16 The metadata interface is implemented on video device nodes. The device can be
17 dedicated to metadata or can support both video and metadata as specified in its
23 Device nodes supporting the metadata capture interface set the
26 ioctl. That flag means the device can capture metadata to memory. Similarly,
27 device nodes supporting metadata output interface set the
30 metadata from memory.
38 The metadata device uses the :ref:`format` ioctls to select the capture format.
39 The metadata buffer content format is bound to that selected format. In addition
50 Devices that capture metadata by line have the struct v4l2_fmtdesc
68 :ref:`four character code <v4l2-fourcc>`. V4L2 defines metadata formats
