Justin Ruggles	7f3a7b5c40	ac3enc: add channel coupling support 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.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	dc7e07ac1f	Add stereo rematrixing support to the AC-3 encoders. This improves the audio quality significantly for stereo source with both the fixed-point and floating-point AC-3 encoders. Update acodec-ac3_fixed and seek-ac3_rm test references. Originally committed as revision 26271 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Justin Ruggles	9907c7804a	eac3dec: make GAQ dequantization 24-bit Originally committed as revision 18888 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	ae04de316f	eac3dec: revert commit r18860. keep the AHT IDCT 24-bit. will make AHT GAQ dequantization 24-bit in a separate commit. Originally committed as revision 18887 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	9a7a71ed4c	eac3dec: use 16-bit pre-mantissas instead of 24-bit in AHT decoding. it is simpler and also fixes a bug in GAQ dequantization. Originally committed as revision 18860 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
