" This patch * calculates average QP as a float, providing slightly improved ratecontrol if the first pass was CBR. * fixes the reported QP if you set both b_stat_read and b_stat_write, allowing 3 pass encoding (or just examination of the 2nd pass's stats)." git-svn-id: svn://svn.videolan.org/x264/trunk@50 df754926-b1dd-0310-bc7b-ec298dee348c

" This patch makes scene-cut detection based on the relative cost of I-frame vs P-frame, rather than just on the number of I-blocks used. It also makes the scene-cut threshold configurable. This doesn't have a very large effect: Most scene cuts are obvious to either algorithm. But I think this way is better in some less clear cut cases, and sometimes finds a better spot for an I-frame than just waiting for the max I-frame interval." git-svn-id: svn://svn.videolan.org/x264/trunk@49 df754926-b1dd-0310-bc7b-ec298dee348c

Removing this bias produces an improvement of .4% - 2% bitrate, depending on content and number of reference frames." git-svn-id: svn://svn.videolan.org/x264/trunk@47 df754926-b1dd-0310-bc7b-ec298dee348c

"Here's a patch that adds some kind of rate control. I suppose it is by no means perfect, but it's much better than constant quantizer. It also has a very crude scene change detection that sometimes avoids a buffer underflow by reencoding oversized P/B frames as I frames." git-svn-id: svn://svn.videolan.org/x264/trunk@17 df754926-b1dd-0310-bc7b-ec298dee348c
