   4 Subject: [PATCH 1186/1215] staging: bcm2835-codec: Disable HEADER_ON_OPEN for
   5  video encode
   6
   7 Video encode can defer generating the header until the first
   8 frame is presented, which allows it to take the colourspace
   9 information from the frame rather than just the format.
  10
  11 Enable that for the V4L2 driver now that the firmware populates
  12 all the parameters.
