flash media server nellymoser codec problem

i am using flash action script 3 for streaming video and audio via web cam and mice to flash media server.as all know that flash uses nellymoser audio codec for recording audio. i want to convert flash media server flv to 3gp for that i am using ffmpeg but after conversion i am getting audio video synchronization problem.

the problem is coming due to the nellymoser audio codec.

here anyone can suggest me right way to stream audio from flash action script to flash media server using AAC or mp3 codec at the time of recording.

is there any other command line converter that can convert flash media server flv to 3gp ?

i found after goggling that it is not possible to force the Microphone/Camera/NetStream classes to use a codec of your choice.

It is, however, possible to transcode the resulting FLV from the server side to something that uses the 3GP container format and AAC for audio.

I have successfully converted flash media server flv to 3gp with AAC codec that 3gp file is playing fine but it has one major problem that is of audio video synchronization that "video comes first and then audio".

I am using ffmpeg higher version command line tool for this.

how can we do so ?

is there any solution for this problem?
