This function should only be called from a @handle_frame implementation.
#GstBaseParse creates initial timestamps for frames by using the last
timestamp seen in the stream before the frame starts. In certain
cases, the correct timestamps will occur in the stream after the
start of the frame, but before the start of the actual picture data.
This function can be used to set the timestamps based on the offset
into the frame data that the picture starts.
