Zdenek Kabelac	30eb039652	* avoids double inclusion of this header (how about making all headers in ffmpeg working this way ?) Originally committed as revision 609 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Zdenek Kabelac	52af45ad77	* baling 8 seems to have the same speed Originally committed as revision 575 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	fbdedc1704	* always baling even though it seems to produce sometime worse results then for -fPIC compilation - don't ask me why... Originally committed as revision 573 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	31ddcf9851	* cleanup for put_pixels_mmx Originally committed as revision 572 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	ec9a41f57d	* somewhat more advanced test suit for dsp code - for now i386 only cd test ; make dsptest ; ./dsptest Originally committed as revision 568 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Zdenek Kabelac	dcb9cd4b81	* added simple test main - see comments about how to compile - should be probably made as a regression test Originally committed as revision 565 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Fabrice Bellard	9241551049	tried to avoid gcc 2.95.2 bug by puting explicit register constraints - added comment about rounding bug in some functions (need to correct or suppress them for regression tests) Originally committed as revision 515 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Juanjo	43f1708f8b	- Added PSNR feature to libavcodec and ffmpeg. By now just Y PSNR until I'm sure it works ok.
