Michael Niedermayer	ae1dd8e125	attempt to implement xiphs useless and stupid quantization matrix mess Originally committed as revision 5775 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	187c9be7a6	replace *_dequant (2 intra, 1 inter) by qmat (3 intra, 3 inter) (needed for theora according to spec) Originally committed as revision 5774 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d2744e19e0	use RSHIFT Originally committed as revision 5773 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	4501e678e7	useless memcpy Originally committed as revision 5772 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	7cfe7fe5e7	some fixmes if someone ever wants to implement theora support correctly ... Originally committed as revision 5771 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 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	18 years ago
Michael Niedermayer	b7f3fdd779	cleanup Originally committed as revision 5769 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Reimar Döffinger	05020c89eb	Split common.h in two parts, purely internal stuff (internal.h) and things available to external programs as well. Also make more things available to external programs like GET_UTF8, MKTAG etc. Originally committed as revision 5765 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 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	18 years ago

Diego Biurrun	2266e085c9	Fix DESTDIR handling. DESTDIR got prepended twice for $(DESTDIR)$libdir and similar since $libdir contained $prefix, which contained $(DESTDIR).. Originally committed as revision 5754 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Stefan Gehrer	77f173bef5	set mvP2 also in PSKIP macroblock Originally committed as revision 5748 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 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	18 years ago
