澄空的花开,掉帧太厉害,基本上看不了,
Format profile : High@L5.0
的关系么 LS的不关level的事,升级cpu吧,要不就是解码或者分离器的问题 笔记本 看这几个参数：
me=umh 稀松平常
me=tesa 给力
me_range=24 稀松平常
me_range=32 还行
me_range=64 给力
ref=6 稀松平常
ref=16 给力（不过有些设备没法硬解了 不包括国产MP4和高清电视
psy_rd=0.30:0.00 细节少 适合动画片
psy_rd=1.00:0.20 细节多 适合电影
crf=19.0 质量挺好 还帮你节省空间了
crf=15.0 似乎质量更好 但更多的是收藏心态了 感谢各位解答
