* commit '50a1c66cf6ab7eb683daaa9e2da3869fa3a54609': ac3_parser: add a public function for parsing the data required by the demuxer avpriv_ac3_parse_header() is left in place but without the GetBitContext parameter, as the mov muxer requires a lot more fields than just bitstream_id and frame_size from the AC3HeaderInfo struct.

2016-09-15avcodec/(e)ac3: Fix target_level for EAC3.Nikolas Bowe
Currently when using target_level with EAC3 it produces silence. This small patch fixes target_level for decoding EAC3. Example: ffmpeg -y -i /tmp/test.wav -acodec eac3 -dialnorm -14 -ac 6 -b:a 384000 /tmp/test.m2ts ffmpeg -y -target_level -24 -i /tmp/test.m2ts -acodec pcm_s16le -f matroska /tmp/out.mkv ffplay /tmp/out.mkv Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2016-04-02eac3dec: don't call avpriv_request_sample every frame.Tim Walker
These errors neither prevent nor stop successful decoding of the E-AC-3 stream's "core", causing avpriv_request_sample to be called for every single frame in the bitstream. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

This is the remaining error, the output on the SPX samples, respectively csi_miami_stereo_128_spx.eac3 and csi_miami_5.1_256_spx.eac3, goes from: stddev: 8.71 PSNR: 77.52 MAXDIFF: 235 stddev:24270.51 PSNR: 22.17 MAXDIFF:47166 to: stddev: 0.12 PSNR:114.12 MAXDIFF: 1 stddev: 0.12 PSNR:114.73 MAXDIFF: 1 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2015-03-14ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContextAndreas Cadhalpun
The AC3DecodeContext has a float (USE_FIXED=0) and an integer (USE_FIXED=1) variant, both of which can be present in the same binary. This is not only very confusing, but it also breaks horribly, when one variant is used by code expecting the other. This currently happens, because eac3dec.c is only compiled for the float variant, but also used from ac3dec_fixed.c, which uses the integer variant. The result is memory corruption, leading to crashes. So compile eac3dec.c once for each variant and adapt it, so that it works with the integer variant. A loss of precission and scaling bug has been fixed by the committer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
