H.264: Don't set data_partitioning for invalid NAL_DPA. · 0410ee8f

Alexander Strange authored Jul 03, 2009

Before, the decoder could interpret a corrupt frame
as a NAL_DPA and NAL_DPC, and then start decoding
even if decode_slice_header() returned an error.
This frequently caused crashes.

Fixes issue1228, issue1229, and partially issue1238.

Fix potentially unaligned accesses in ff_copy_bits() · ec62d942

Måns Rullgård authored Jul 01, 2009

A pointer should never be assigned a value which may have less than the
required alignment of the target type. Compilers may assume pointer
values have the required alignment, and emit normal load/store instructions.

Unaligned pointers should use a character type or compiler-specific
type modifiers.
