   4 Subject: [PATCH] staging:vc04_services: bcm2835-codec: Request headers
   5  with I-frame
   6
   7 V4L2 wishes to have the codec header bytes in the same buffer as the
   8 first encoded frame, so it does become 1-in 1-out for encoding.
   9 The firmware now has an option to do this, so enable it.
