Nikolas Bowe	96cd6f672e	avcodec/(e)ac3: Fix target_level for EAC3. 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>	8 years ago
Tim Walker	fef2147b7a	eac3dec: don't call avpriv_request_sample every frame. 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.

Christophe Gisquet	0c3339f4bd	eac3dec: fix scaling 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>	10 years ago
Andreas Cadhalpun	7b05b5093e	ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContext 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>	10 years ago
