* various subband encoders (all either worse or complicated so they are ↵Michael Niedermayer2004-08-02
| | | | | | | | commented out) different 0-context encoding, 1.2% lower bitrate (foreman@352x288 qscale=8) no significant change at qscale=1 Originally committed as revision 3366 to svn://svn.ffmpeg.org/ffmpeg/trunk
* 1/0 fixMichael Niedermayer2004-07-28

* dont segfault without -strict -1Michael Niedermayer2004-07-28

* optimize quantizaton (about 3x faster)Michael Niedermayer2004-07-27
| | | | | | further opt is easily possible but could lead to overflows depening upon coefficient range, so this wont be done yet as it would make the code somewhat less flexible Originally committed as revision 3354 to svn://svn.ffmpeg.org/ffmpeg/trunk
* cleanupMichael Niedermayer2004-07-27
| | | | | | | | remove ugly and slow vertical scaning code 0.1% bitrate increase (foreman@352x288 qp=1) 0.3% bitrate increase (foreman@352x288 qp=8) Originally committed as revision 3353 to svn://svn.ffmpeg.org/ffmpeg/trunk
* use parent sample to predict significance & magnitudeMichael Niedermayer2004-07-27
| | | | | | 1% bitrate reduction (foreman@352x288 qscale 1 & 8) Originally committed as revision 3352 to svn://svn.ffmpeg.org/ffmpeg/trunk
* log2() & bsdMichael Niedermayer2004-07-27
| | | | Originally committed as revision 3350 to svn://svn.ffmpeg.org/ffmpeg/trunk
* better context model (0.2-1% lower bitrate)Michael Niedermayer2004-07-27
| | | | | | a tiny bit cleanup Originally committed as revision 3348 to svn://svn.ffmpeg.org/ffmpeg/trunk
* typoMichael Niedermayer2004-07-26

* my experimental wavelet codecMichael Niedermayer2004-07-25
note, this is far from finished, dont expect todays encodings to be decodeable with cvs tomorrow ... Originally committed as revision 3341 to svn://svn.ffmpeg.org/ffmpeg/trunk
