Michael Niedermayer	fccd85b9f3	avcodec: fix aac/ac3 parser bitstream buffer size Buffers containing copies of the AAC and AC3 header bits were not padded before parsing, violating init_get_bits() buffer padding requirement, leading to potential buffer read overflows. This change adds FF_INPUT_BUFFER_PADDING_SIZE bytes to the bit buffer for parsing the header in each of aac_parser.c and ac3_parser.c.

Michael Niedermayer	e6d9fa66f1	ac3dec: Move center and surround mix level tables to the parser. That way all mix levels as exported by avpriv_ac3_parse_header() will have the same meaning. Previously the 3-bit center mix level for E-AC-3 was used to index in a 4-entry table, leading to out-of-array reads.

Michael Niedermayer	99a42f3fa9	ac3dec: Move center&surround mix level tables to parser. That way all mix levels as exported by the parser will have the same meaning. Previously the 3bit center mix level for eac3 was used to index in a 4 entry table leading to out of array reads. this change removes the table and offsets the ac3 variable by 4 so it matches the meanings for eac3 except the reserved case. The reserved case is then explicitly handled. Idea-by: Justin Ruggles <justin.ruggles@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
