Michael Niedermayer	5ced7b80ad	disable the vp3 mmx and sse2 idcts, their output doesnt match the c idct (tested with -f crc) and the theora spec does not allow different idcts not to mention the difference is quite vissible ... Originally committed as revision 5788 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	e278056fba	check how many bits are left after decoding extradata this change is messy as whoever wrote the original code copied the GetBitContext instead of passing a pointer to it which has to be fixed for the above thing Originally committed as revision 5770 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	408ec4e2a6	calculate all coefficients for several orders during cholesky factorization, the resulting coefficients are not strictly optimal though as there is a small difference in the autocorrelation matrixes which is ignored for the smaller orders Originally committed as revision 5758 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Stefan Gehrer	77f173bef5	set mvP2 also in PSKIP macroblock Originally committed as revision 5748 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	ab01b2b82a	optionally (use_lpc=2) support Cholesky factorization for finding the lpc coeficients this will find the coefficients which minimize the sum of the squared errors, levinson-durbin recursion OTOH is only strictly correct if the autocorrelation matrix is a toeplitz matrix which it is only if the blocksize is infinite, this is also why applying a window (like the welch winodw we currently use) improves the lpc coefficients generated by levinson-durbin recursion ... optionally (use_lpc>2) support iterative linear least abs() solver using cholesky factorization with adjusted weights in each iteration compression gain for both is small, and multiple passes are of course dead slow Originally committed as revision 5747 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Diego Biurrun	2f30a81d19	CONFIG_WIN32 implies MinGW and Cygwin and possibly more, so use just CONFIG_MINGW or __MINGW32__ instead. Originally committed as revision 5718 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
