* ac3dec: change logging of skipped E-AC-3 substreams.Tim Walker2016-04-02
| | | | | | | | | Change log level from warning to debug: the E-AC-3 "core" substream can be successfully decoded without the additional and dependent substreams, and their presence is already indicated via avpriv_request_sample in ff_eac3_parse_header. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| | | | | Amplification of quiet sounds is enhanced. Inspired by gbooker's A52Decoder.

* ac3dec: make drc_scale exponentiallyJohn Stebbins2013-12-09
| | | | | | | The a52 spec suggests that "partial compression" should scale the drc value in this manner. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavc: change all decoders to behave consistently with AV_EF_CRCCHECK.Anton Khirnov2013-10-28
| | | | | | Just crccheck prints a warning, crccheck+explode returns an error. Also document this behavior.

* ac3dec: Don't consume more data than the actual input packet sizeMartin Storsjö2013-07-15
| | | | | | | | | | | | | | | 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.

* ac3dec: Increment channel pointers only once per channelMartin Storsjö2013-07-13
| | | | | | | | 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>

* ac3dec: ensure get_buffer() gets a buffer for the correct number of channelsJustin Ruggles2012-10-01
| | | | | | | | | | | 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

| | | | | | | | | | | | 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.
