Server could not record G.711?

Hi,

I live a stream to the application "livepkgr" with H.264 and G.711(come from IP camera), I can get the video and audio from player, but there is only video data in the .f4f file, no sound data.

and in the .flv file(when with "record"), there is only audio data.

Doea anyone know why this happened?

Should I set some configuration or something?

Thanks.
