同样是AVC1为什么别人的视频快进可以精确跳2秒,我自己编码的视频就5~12秒随机跳?

    兄弟,找到问题所在了,应该是播放器的问题,你用shanaFFplayer,也就是shana播放器播放的时候按一下f1,按键d,f是向左向右1s关键帧,用这个就是1s跳转(前提是有关键帧,不然不会跳转),我试了一下,关键帧快速设置为1确实做到了每一秒至少一个i帧,这个会在shana播放器的最下方实时显示当前帧类型.

     

    简言之是播放器的设定,比如potplayer和shana播放器默认方向键左右都是五秒[笑哭]如果你真想测试可以把鼠标放在每一秒上,它只能跳在关键帧上,如果你的关键帧不存在,他就会寻找最近的关键帧,例如你选了15s,实际最近的关键帧在18s,它就回跳到18s上.

     

    经过我的测试每秒都可以用鼠标跳转,shana也显示存在I帧.如果说其他视频能直接跳转1s而这个做不到,那么大概是你的设置方式有问题,例如你选择了独立模式,但你只在全局中修改了预设,没有将预设应用到视频上,此时视频还是走的老预设 当然,也可能是播放器不同导致的设定不同,在最低跳转五秒的设定里,关键帧为1和5对你的体验是差不多的
