John Stebbins	c9ca220ef2	ac3dec: make drc_scale exponentially The a52 spec suggests that "partial compression" should scale the drc value in this manner. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Christophe Gisquet	b6293e2798	fmtconvert: Explicitly use int32_t instead of int Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	8f24c12be7	ac3dec: Don't consume more data than the actual input packet size This was handled properly in the normal return case at the end of the function, but not in this special case. Returning a value larger than the input packet size can cause problems for certain library users. Returning the actual input buffer size unconditionally, since it is not guaranteed that frame_size is set to a sensible value at this point.

Martin Storsjö	031be5b41b	ac3dec: Consistently use AC3_BLOCK_SIZE and sizeof Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	68e57cde68	ac3dec: Increment channel pointers only once per channel If the channel mapping map multiple output channels to one input channel, we should only increment the actual pointer once. Cc: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Justin Ruggles	d7c450436f	ac3dec: validate channel output mode against channel count Damaged frames can lead to a mismatch, which can cause a segfault due to using an incorrect channel mapping. CC:libav-stable@libav.org	12 years ago

Mathias Rauen	04ea5491a8	ac3dec: fix non-optimal dithering of zero bit mantissas Use a noise range of -0.707 to 0.707 instead of -0.5 to 0.5 Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago

Diego Biurrun	717addecad	Use proper return values in case of missing features	12 years ago
Justin Ruggles	56b6a43056	ac3dec: ensure get_buffer() gets a buffer for the correct number of channels If there is an error during frame parsing, but AVCodecContext.channels was changed and AC3DecodeContext.out_channels was set previously, the two may not match. Fixes CVE-2012-2802 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago

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.
