   4 Subject: [PATCH] staging: bcm2835_codec: Include timing info in SPS
   5  headers
   6
   7 Inserting timing information into the VUI block of the SPS is
   8 optional with the VPU encoder.
   9 GStreamer appears to require them when using V4L2 M2M, therefore
  10 set the option to enable them from the encoder.
