2013-12-09 | ac3dec: make drc_scale exponentially | John Stebbins | |
The a52 spec suggests that "partial compression" should scale the drc value in this manner. Signed-off-by: Anton Khirnov <anton@khirnov.net> | |||

2013-10-28 | lavc: change all decoders to behave consistently with AV_EF_CRCCHECK. | Anton Khirnov | |
Just crccheck prints a warning, crccheck+explode returns an error. Also document this behavior. | |||

2013-07-15 | ac3dec: Don't consume more data than the actual input packet size | Martin Storsjö | |
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.

2013-07-13 | ac3dec: Increment channel pointers only once per channel | Martin Storsjö | |
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> | |||

2013-02-24 | ac3dec: validate channel output mode against channel count | Justin Ruggles | |
Damaged frames can lead to a mismatch, which can cause a segfault due to using an incorrect channel mapping. CC:libav-stable@libav.org | |||
2013-02-12 | ac3: decode directly to the user-provided AVFrame | Justin Ruggles | |
2013-01-20 | ac3dec: fix non-optimal dithering of zero bit mantissas | Mathias Rauen | |

2012-10-01 | ac3dec: ensure get_buffer() gets a buffer for the correct number of channels | Justin Ruggles | |
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 | |||

2012-02-10 | ac3dec: Move center and surround mix level tables to the parser. | Michael Niedermayer | |
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.
