Dear list member,
I am Jorge FELIU, french student engineer, and I am implementing the frame 
rate control based on L.1 of Annex L of ISO/IEC 14496-2. I am not sure about 
the settings of some of the
parameters. My questions are as follows:
1. How to define a sequence (or segment)? Is it defined as the frames
between two I-frames?Or is it a group of GOP?
2. How to define Nr which is defined as the number of P-frames remaining
for encoding? How can I know in advance how many P-frames are in the
sequence?
3. What is "total_data_number" in the UpdateRDModel function?
4. I've a query on the correctness of a "for loop" of the UpdateRDModel
function on page 478. I think the "for loop" should be "for (i=n-w;
i<=n; i++)" instead of "for (i=n; i>n-w; i++)".
I am looking forward, best regards.
Jorge FELIU
