[Mp4-tech] Type of Reference frames?

[Alexis Michael Tourapis]

Dear Janis,
Please take a look at how the parameter PyramidCoding affects the behavior
of the encoder. Depending on how it is set, it allows you to also enables
pictures containing B slices to be referenced. I would recommend checking
the latest reference software manual (last version was at JVT-017) for
example settings. 
For your reference, in the next release the use of BReferencePictures is
also getting updated, allowing B slices in the "primary" coding level. I am
not sure when Karsten will be able to release this though.
Best regards,
Alexis

Hello, 
Thanks for the previous help.
In JM 9.3, I guess it used only I or P frames as reference frames for
interprediction.
If B frames are also used, how can I see it?
Thank you in advance.
