[已解决]关于htc hd2的视频

whitestone@2010-04-04 13:05

htc hd2,自己用dshow2raw压,发现只有在baseline的时候能比较流畅的播放,一旦用main,立刻播放就卡。但网上下的一些视频,有main@3.0的,high@4.0的,cabac on,都能流畅播放

x264.exe --crf 22 --profile main --level 3.0 --me umh --subme 10 --sar 1:1 --threads auto --thread-input --versioninfo

用的dshow2raw,weightp和b-pyramid应该都是关的,但播放很卡……求助……

开CABAC,关bframe可以流畅 ?

关了b帧的main不是真man,还不如老老实实用Baseline呢
