* | avcodec/(e)ac3: Fix target_level for EAC3.Nikolas Bowe2016-09-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | 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>

* | ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContextAndreas Cadhalpun2015-03-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * ac3enc: add channel coupling supportJustin Ruggles2011-05-241-5/+0
| | | | | | | | | | | | | | | | | | Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies.

Add AVX FFT implementation. Increase alignment of av_malloc() as needed by AVX ASM. Update x86inc.asm from x264 to allow AVX emulation using SSE and MMX. mjpeg: Detect overreads in mjpeg_decode_scan() and error out. documentation: extend documentation for ffmpeg -aspect option APIChanges: update commit hashes for recent additions. lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enums aac: add headers needed for log2f() lavc: remove FF_API_MB_Q cruft lavc: remove FF_API_RATE_EMU cruft lavc: remove FF_API_HURRY_UP cruft pad: make the filter parametric vsrc_movie: add key_frame and pict_type. vsrc_movie: fix leak in request_frame() lavfi: add key_frame and pict_type to AVFilterBufferRefVideo. vsrc_buffer: add sample_aspect_ratio fields to arguments. lavfi: add fieldorder filter scale: make the filter parametric ...
