-Subject: [PATCH] staging: bcm2835-camera: Ensure H264 header bytes get
- a sensible timestamp
-
-H264 header come from VC with 0 timestamps, which means they get a
-strange timestamp when processed with VC/kernel start times,
-particularly if used with the inline header option.
-Remember the last frame timestamp and use that if set, or otherwise
-use the kernel start time.
