Get instant bitrate from H.264 encoder ?

[Jean-Michel Hautbois]

Hi all,

I am wondering if it is possible to get a message from the encoders in
gstreamer, more precisely, from the H.264 encoder, which would give
the instant bitrate.
What I call instant bitrate is the bitrate for each frame after
encoding this frame.
This would be useful in order to implement some algorithms like scene
detection change in a robust way.

Thanks in advance for answering,
Regards,
JM
