I do not know the bitstream format, but this seems likely
to be what was intended. Also add a check on the number of
items to read.

h264parser: fix access to uninitialized memory
...
When vui->timing_info_present is 0, vui->fixed_frame_rate_flag and others
cannot be accessed since they have not been set.
It was also possible that sps->fps_{num,den} end up initialized here.

basecamerasrc: optimize state changing speed
...
Create preview pipeline already in initialization phase. This speeds
up NULL_TO_READY state change. Also implement a separate function for
setting the preview filter element.
This also restricts the preview filter property to work only on
NULL state.
