About b pyramid encoding oder

[palmman]

Hi guys,

If a GOP is I-B1-B2-B3-P1-B4-B5-B6-P2. In b pyramid, its encoding order is I-P1-B2-B1-B3-P2-B5-B4-B6. If I would like to modify it as I-P1-P2-B2-B5-B1-B4-B3-B6, is it reasonable? I am not sure whether my thought is correct. Many thanks for your reply.

Why do you do this? You increase decoding delay from 2 frames to 4 frames.

Thanks a lot. The thought just suddenly occurred to me. So is it possible to realize? BTW, I get a bit perplexity about "decoding delay from 2 frames to 4 frames"? I just change encoding order, decoding order should be the same.
