Justin Ruggles	266d24be4a	Move large arrays to AC3EncodeContext rather than passing them around. Originally committed as revision 26012 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	7da4dc17d9	cosmetics: line wrap and spacing Originally committed as revision 26011 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	a0d763fc88	Use a single value for SNR offset in the bit allocation search rather than the separate coarse and fine values. Originally committed as revision 26010 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	70fcd7ea80	Change bit_alloc() to return the mantissa bit count. Originally committed as revision 26009 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	937cd1467c	cosmetics: alignment and line wrap after last commit Originally committed as revision 26008 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	359c1d1926	Move bit counts to AC3EncodeContext. Originally committed as revision 26007 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	793bbf9544	Split out setting of bit allocation parameters to a separate function. Th new function only needs to be called at initialization because bit allocation parameters currently do not change during encoding.

Justin Ruggles	12ed622699	Deinterleave whole frame at once instead of per-block. This reduces the amount of memcpy() by using pointers to overlap samples for successive blocks rather than copying. Originally committed as revision 25986 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	e0685bc98f	cosmetics: add & alter some comments Originally committed as revision 25985 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Justin Ruggles	99ca4f73f0	Don't use nested loops to iterate valid sample rates. Eliminates a goto and mirrors the bitrate validation. Originally committed as revision 25980 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	1607db0a95	Remove some duplicate local copies of avctx fields. This is an av_cold function, and we don't need to duplicate variables just to save a few characters. Originally committed as revision 25979 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	8f60f70d44	Split validation of initial user options into a separate function. Originally committed as revision 25978 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
