AMR Muxer for RTP

AMR Muxer for RTP:
--------------------
1.Input : AMR File
2.Output : AMR RTP Packet Data ( which contains 500 ms of data..
25 Frames * 20 ms)
Read 25 Frames and make it as like RTP amr data as follows:
i) F0,25 frames header and AMR Data
ii)


I have to test the RTP Muxer completely;

RTP Muxer is having problem;
RTP Demuxer will do the following:
1.F0 BC BC BC ... 3C
2.Number of BC's indicate the number of frames + 1 is number of frames in a RTP packet;
RTP muxer will have 24 BCs and 1 3C

About this BC value;
we can generate this value according the selected type:
3C refers 12.2 kbps
0111
1 0111 1 00

F FT Q 00
1 0111 1 00
F indicates the continuation of another Speech frame;
if F is 0 means that is the last speech frame;
After BC's, 3C is the last speech frame;
the Upper most bit is zero , so it is the last frame;
1 indicates continuation;

In case of 3C just check it...
0 0111 1 00


RTP Stack is sending the data correctly;
_ Working welland I have received the data properly
