Audio and Video Port Problem in Audio Testing

RTP AMRTesting :
=================
1.I combined the multiple RTP packets in to a Single packet and passed it to the AMR Paser application;
2.Next added the AMR file extension and AMR start codes and try to play it with QT Player;
Created AMR file is wroking with QT Player; It is working.

3.Pls kindly check the Market Bit of the RTP header format;

if we are sending the audio and video thru INVC transcoder,I printed the RTP packet Number as follows:
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 60, Buffer size = 1389, Marker = 0
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 61, Buffer size = 1389, Marker = 0
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 62, Buffer size = 1389, Marker = 0
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 6, Buffer size = 28, Marker = 128
RTP packet Number = 63, Buffer size = 1389, Marker = 0

ffmpeg sends amr audio to RTP.I got the following:
RTP packet Number = 3, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 3
RTP packet Number = 4, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 4
RTP packet Number = 5, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 5
RTP packet Number = 6, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 6
RTP packet Number = 7, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 7
RTP packet Number = 8, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 8
RTP packet Number = 9, Buffer size = 1389, Marker = 0 HSB = 0 , LSB= 9


while sending audio and video we have the problem;One more thing if we send audio and video, QuickTime player is able to render the audio.


So without the packet number we need to do parsing;
Every Audio Frame Beginning is marked by the Marker bit as Zero;otherwise it will be 1 or TRUE;
If I developed the amr parser for this scenario, It causes the Screech Sound in audio with particular interval.At client side, I received the RTP packets and Dumped it into a file also givesthe same problem;

Solution:
-----------------

Finally I got the Solution:
we are sending video data at 5000 Port We are sending audio data at 5001 Port ;So it causes the problem;
Instead of it If I changed the things as
video as 4500 and Audio as 5000 means there will be no problem So Every RTP amr packet is having header Info;
For Audio and video There must be some difference.So that we can avoid this situation;
