Hi:
I have this SDP in my wowza server, for receiving a stream

v=0
o=- 0 3641250070 IN IP4 XX.XX.XX.XX
s=Wowza Media Server
c=IN IP4 XX.XX.XX.XX
t=0 0
m=audio 10000 RTP/AVP 0
a=rtpmap:0 PCMU/8000
a=ssrc:3610129879 cname:user3527564912@host-d993365d
m=video 10002 RTP/AVP 101
a=rtpmap:101 H264/90000
a=ssrc:276642451 cname:user3527564912@host-d993365d

The stream is being received great(I can hear and I can watch it from rtmp://[my-wowza-ip]:1935/[app]/filename.sdp), but when I try to record it with Wowza, the generated .mp4 file has no audio.
With .flv it works, but with .mp4 no.

What can be happening?
