012c40140f codecparsers: fix < 0 issue of guint in mpeg4 parser 
gst_byte_reader_masked_scan_uint32 returns a guint, not a gint, which
explains the issue we sometime get using < 0 instead of == -1;

c4d987b6d3 codecparsers: Variant of _identify_nalu without checks 
This is useful for cases where the caller *knows* that the provided
input contains a whole NALU and can therefore avoid:
* the expensive checks for the next start code (which won't be present)
* delaying the input parsing (since we would need the next incoming NALU
  in order for the parsing code to detect the next start code)

12c678c7cf codecparsers: minor fixes 
Const-ify one more VLC table. Fix spelling of 'hybrid'.
No need to explicitly call ensure_debug_category() everywhere,
that will be done automatically from GST_LOG() and friends
via GST_CAT_DEFAULT.

c75922b96b basevideodecoder: fix weird event list handling 
Get rid of weird code that copies a list manually, taking
ownership of the elements and then frees the old list. Instead,
just take over the old list entirely. (If the intent was to
reverse the list, one could use g_list_reverse() instead).

Then, push events in the list out from last to first (since they
were prepended as they came in) instead of just pushing out the
last in the list and leaking the others.

ca2f96caac vc1parser: do not overwrite buffer 
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.

fd4eb2e220 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.

de138dbc57 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.
