-Subject: [PATCH] staging: bcm2835-camera: Ensure timestamps never go
- backwards.
-
-There is an awkward situation with H264 header bytes. Currently
-they are returned with a PTS of 0 because they aren't associated
-with a timestamped frame to encode. These are handled by either
-returning the timestamp of the last buffer to have been received,
-or in the case of the first buffer the timestamp taken at
-start_streaming.
-This results in a race where the current frame may have started
-before we take the start time, which results in the first encoded
-frame having an earlier timestamp than the header bytes.
-
-Ensure that we never return a negative delta to the user by checking
-against the previous timestamp.
