Justin Ruggles	a521aadfe8	cosmetics: reindent after last commit Originally committed as revision 19589 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	25dcd1823c	ac3dec: simplify zero-bit mantissa dithering by calculating it conditionally during mantissa decoding, then only removing it from the coupling range for coupled channels which do not use dithering. Originally committed as revision 19588 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	b972c06a8f	cosmetics: indentation and line wrap Originally committed as revision 19587 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	c36ea0600c	cosmetics after last commit Originally committed as revision 19586 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	3f93716809	Modify decode_band_structure() so that the actual band structure is only used within the function. This removes the need to have the coupling band structure stored in the AC3DecodeContext. Originally committed as revision 19585 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	603139022d	Use coupling band sizes instead of coupling band structure when calculating coupling transform coefficients. Originally committed as revision 19584 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	eb98cdfa8d	cosmetics: add more detailed information to the documentation for decode_band_structure(). Originally committed as revision 19577 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	d15153244f	refactoring: properly separate AC-3 and E-AC-3 code Originally committed as revision 19501 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	89547cfb36	Make sure that eac3_decoder only gets enabled when CONFIG_EAC3_DECODER is set. Originally committed as revision 19500 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ronald S. Bultje	ce863d7f36	Rename ff_log_missing_feature() to av_log_missing_feature(). Originally committed as revision 19294 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
Diego Biurrun	1754fe4d30	The AC-3 decoder is now LGPL. Exchange the license header and change references in the build system and documentation that mark it as GPL. Originally committed as revision 18876 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	d869a460db	LGPL version of ac3_decode_transform_coeffs_ch, ~12.4% faster. Originally committed as revision 18875 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
Justin Ruggles	1ac7d1ac50	ac3dec: fix coupling range check. the start subband must be less than the end subband. Originally committed as revision 18857 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	778bc09bbe	cosmetics: line wrap and vertical alignment Originally committed as revision 18752 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	396b73c7f7	ac3dec: Remove unneeded context variable, num_cpl_subbands. It is also not needed for spectral extension or enhanced coupling since it is redundant information, so I am removing it from decode_band_structure() as well. Originally committed as revision 18751 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	52dc3fc83d	cosmetics: indentation after last commit Originally committed as revision 18750 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Justin Ruggles	95f3019a51	ac3dec: reorder output channels to SMPTE channel order Originally committed as revision 18542 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
