有些解码器不能完全支持open-GOP码流，
|

例如蓝光解码器，因此在x264里面open-GOP是默认关闭的。

对于解码端，接收到的码流如果如下:I0 B0 B1 P0 B2 B3...这就是一个open-GOP码流（I帧后面紧跟B帧）。

因此B0 B1的解码需要用到I0前面一个GOP的数据，B0 B1的dts是小于I0的。

如果码流如下: I0 P0 B0 B1 P1 B2 B3...这就是一个close-GOP码流，

I0后面所有帧的解码不依赖于I0前面的帧，I0后面所有帧的dts都比I0的大。
|
||||
如果码流是IDR0 B0 B1 P0 B2 B3...那个这个GOP是close-GOP，B0,B1虽然dst比IDR0小，
|

但编解码端都刷新了参考缓冲，B0,B1参考不到前向GOP帧。

对于编码端，如果编码帧类型决定如下: ...P0 B1 B2 P3 B4 B5 I6这就会输出open-Gop码流 （P0 P3 B1 B2 I6 B4 B5...），

|

如果一个GOP的最后一帧（上例中是第5帧）设置为B帧，
