Hello all...just discovering gstreamer and think it's awesome!

I'm trying to mix multiple rtmp streams together using videomixer...I feel
like i'm getting close but I can't seem to get it going.  Here's what I
have now (and I've tried what feels like thousands of variations of this),
any help pointing me in the right direction is appreciated:

gst-launch-1.0 -e rtmpsrc
location='rtmp://fms.vokledev.com/gstreamer/test1live=1' ! flvdemux !
decodebin ! video/x-flv, width=350, height=250 ! \
videomixer name=mix ! rtmpsink location="rtmp://
fms.vokledev.com/gstreamer/gstream live=1" \
rtmpsrc location='rtmp://fms.vokledev.com/gstreamer/test2 live=1' !
flvdemux ! decodebin ! video/x-flv, width=350, height=250  ! videoconvert !
mix.

Gives me the error:

WARNING: erroneous pipeline: could not link mix to rtmpsink0

I've been able to do other things with an rtmp stream, like reading one in
and pushing it back out to flash media server, but this one has had me on
the ropes for a couple of days now.

Thanks in advance,

Rich
