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.

from the "Table 265: Sequence Layer Data Structure" of the specification
for the library to be more flexible.
