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.

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
Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Michael Niedermayer	eda3758c87	ac3dec: update checked AV_EF flags. A user who wishes to use default error concealment cannot set the AV_EF_CRCCHECK flag because not every CRC in every format is a reliable indicator of bitstream damage. In some formats crcrs can be nonsensical in absence of any damage. We thus add the AV_EF_CAREFUL flag in addition to the AV_EF_CRCCHECK flag to allow a user to enable this reliable CRC check without having to enable all CRC checks in all formats.

Justin Ruggles	9aa8193a23	Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbis decoders. Based on patches by clsid2 in ffdshow-tryout.	14 years ago
Reimar Döffinger	636ee66f1c	Fix data_size handling for AC3 and dca decoders. They use now code identical to the AAC decoder. The AC3 decoder previously did not check the data_size and the dca decoder checked against and set wrong values for float.	14 years ago
Reimar Döffinger	4c7ad768e1	ac3dec: allow selecting float output at runtime.	14 years ago
Justin Ruggles	4c64c8e95a	ac3dec: fix processing of delta bit allocation information. The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero.	14 years ago

Reimar Döffinger	4c886d613d	Detect byte-swapped AC-3 and support decoding it directly. This allows the AC-3 decoder to be used directly with RealMedia decoders that unlike the libavformat one do not byte-swap automatically. Since the new code is only used in case we would fail directly otherwise there should be no risk for regressions.	14 years ago
