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.

e1bacb4813 codecparser: mpeg4: Look for resync code in _mpeg4_parse
This way the API is simpler and users can call 1 single function for packet
detection.

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.
