Michael Niedermayer	396a5e6837	store a few values in the header as difference to the last this makes frames a few bytes smaller (0.1% for high bitrate but >1% for low bitrates) Originally committed as revision 7401 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	3b9cf3bdb3	i think this if() is useless lets abuse our users to test this ;) Originally committed as revision 7344 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	2f16af0667	skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome) Originally committed as revision 7343 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	59743d16c7	dont randomly disallow intr4v in adaptive quant some PSNR/bitrate gain if adaptive quant is used initalize qscale_table correctly (it was pretty much random since the qp->lambda change) this probably has not much effect as the table isnt used currently IIRC Originally committed as revision 7342 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	51b1a6c939	dont randomly dissallow direct MBs some PSNR/bitrate gain for b frames with adaptive quant or QPRD Originally committed as revision 7341 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	e4d0e2edb9	fix special casing of the 0,0 MV for b frames (slight PSNR/bitrate gain) Originally committed as revision 7334 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Michael Niedermayer	ff8dc81b5b	dont favor the zero MV if mv0 is used (psnr per bitrate gains ranging from 0 to 0.14, most are <=0.04 though) Originally committed as revision 7333 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Benjamin Larsson	162b983598	av_log(NULL,... -> av_log(avctx,.. where appropriate. Originally committed as revision 7319 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Benjamin Larsson	e7a6d5f313	Bug fix for crashes when SSE is used on unaligned arrays. No measureable change in speed. This gave random crashes on Win32 and BeOS. The cause for this bug is that gcc doesn't align the stackframe. Linux and glibc always ensure this to be true thus this never affected Linux.
