| | | | | | | | | | but can be extended to other block sizes easily) different intra block coding (previous was just an ugly hack) 1.8% bitrate reduction -0.01PSNR (foreman@352x288 qscale=8) 1.5% bitrate reduction +0.05PSNR (foreman@352x288 qscale=1) Originally committed as revision 3416 to svn://svn.ffmpeg.org/ffmpeg/trunk
* 4x4 SSE compare functionMichael Niedermayer2004-08-22
| | | | | | | | wavelet based compare functions make epzs_motion_search() more flexible so it can be used for a wider range of block sizes make get_penalty_factor() independant of MpegEncContext Originally committed as revision 3410 to svn://svn.ffmpeg.org/ffmpeg/trunk

* clip input motion vectorsMichael Niedermayer2004-06-10
| | | | | | | | | be somewhat more tollerant on invalid input return INT_MAX instead of -1 for unuseable mv/mb types as that ensures nicely that they arent used initalize limits earlier for b frames a few more asserts to check for out of picture vectors Originally committed as revision 3213 to svn://svn.ffmpeg.org/ffmpeg/trunk

* change qscale -> lambda for the motion estimationMichael Niedermayer2004-06-03
| | | | | | | finetune bit/distortion weighting factor used in motion estimation, the old coeffs where finetuned relative to incorrect mv_penalty tables which where then fixed later but the coeffs where not this _may_ fix the long standing blocking artifacts, but may also introduce mudding artefacts theoretically, so please tell us if u stumble across any so we can either fix them or export this variable so the user can change it Originally committed as revision 3189 to svn://svn.ffmpeg.org/ffmpeg/trunk

* motion estimation cleanupMichael Niedermayer2004-04-22
| | | | | | | replace ugly macros by always_inline functions, that way its much more readable and flexible as always_inline can simply be removed while the macros couldnt be about 0.5 % speedup with default parameters Originally committed as revision 3037 to svn://svn.ffmpeg.org/ffmpeg/trunk
