Mux pipeline problem

[JPM]

Hi,

The follow pipeline mux two UDP streams (video from a camera and audio from
a microphone) to a mkv file.

gst-launch-1.0 -q udpsrc multicast-group=224.1.1.1 auto-multicast=true
port=6000 ! jpegparse ! \
queue ! mux. udpsrc multicast-group=224.1.1.2 auto-multicast=true port=6000
! \
audio/x-raw,format=S16LE,rate=48000,channels=1 ! volume volume=10 ! queue !
\
mux. matroskamux streamable=true name=mux ! filesink location=test.mkv

Everything is OK but when the server does not send audio the video disappear
in mkv file.

Any alternative pipeline to fix this problem ?.

Regards
