[讨论]linux下播放高清影视确实不如win下!
我在win下安装了CoreAVC DShow H.264 decoder播放1920*1080格式测试视频,播放流畅,没有断断续续现象,
在linux(arch)下,自己编译MPlayer-1.0rc2加入了CoreAVC DShow H.264 decoder编码,并且安装了mplayer的全部编码all-20071007.tar.bz2。最后用
mplayer -vc coreavc 播放同一1920*1080格式测试视频,发现画面断断续续的,看不到全部的画面,特别是高清的图片式视频。
下面是在win下播放的文件信息:

终端下播放有下面信息:视频、音频编码都正确吧?
