+     For the decoding end, if the received bitstream is as follows: I0 B0 B1 P0 B2 B3... This is an open-GOP bitstream (I frame followed by B frame).
+     Therefore, the decoding of B0 B1 needs to use the data of the GOP before I0, and the dts of B0 B1 is less than that of I0.
+     If the bitstream is as follows: I0 P0 B0 B1 P1 B2 B3... This is a close-GOP bitstream,
+     The decoding of all frames after I0 does not depend on the frames before I0, and the dts of all frames after I0 is greater than that of I0.
+     If the bitstream is IDR0 B0 B1 P0 B2 B3... then this GOP is close-GOP, although the dst of B0, B1 is smaller than that of IDR0,
+     But both the encoder and decoder refresh the reference buffer, B0, B1 cannot refer to the forward GOP frame.
+     For the encoding end, if the encoding frame type is determined as follows: ...P0 B1 B2 P3 B4 B5 I6 This will output an open-Gop bitstream (P0 P3 B1 B2 I6 B4 B5...),
+     The decoding of B4 B5 depends on P3.
+     If the encoding frame type is determined as follows...P0 B1 B2 P3 B4 P5 I6, then this will not output an open-GOP bitstream (P0 P3 B1 B2 P5 B4 I6...).
+     The difference between the two is whether the 5th frame before I6 is set to B frame or P frame,
+     If the last frame of a GOP (the 5th frame in the example above) is set to B frame,
+     This bitstream is open-GOP, and setting it to P frame is close-GOP.
+     Since B frames have better compression performance than P frames, open-GOP performs slightly better than close-GOP in terms of encoding performance,
+     But for compatibility and less trouble, it's better to turn off opne-GOP.
