187 decode_vbi_line: video decoders that support sliced VBI need to implement
188 this ioctl. Field p of the v4l2_sliced_vbi_line struct is set to the
189 start of the VBI data that was generated by the decoder. The driver
190 then parses the sliced VBI data and sets the other fields in the
191 struct accordingly. The pointer p is updated to point to the start of
192 the payload which can be copied verbatim into the data field of the
193 v4l2_sliced_vbi_data struct. If no valid VBI data was found, then the
194 type field is set to 0 on return.
195
196 s_vbi_data: used to generate VBI signals on a video signal.
197 v4l2_sliced_vbi_data is filled with the data packets that should be
198 output. Note that if you set the line field to 0, then that VBI signal
199 is disabled. If no valid VBI data was found, then the type field is
200 set to 0 on return.
201
202 g_vbi_data: used to obtain the sliced VBI packet from a readback register.
203 Not all video decoders support this. If no data is available because
204 the readback register contains invalid or erroneous data -EIO is
205 returned. Note that you must fill in the 'id' member and the 'field'
206 member (to determine whether CC data from the first or second field
207 should be obtained).
208
209 s_std_output: set v4l2_std_id for video OUTPUT devices. This is ignored by 187 s_std_output: set v4l2_std_id for video OUTPUT devices. This is ignored by
