Mixing lossy live sources

Hello,

Can you advise me on the following point.

I'm mixing two RTMP live sources with the compositor element :
rtmpsrc (do-imestamp=true) ==>
                                                       compositor ==>
rtmpsink (sync=true)
rtmpsrc (do-imestamp=true)  ==>

But the sources are coming from cellphones, through a lossy network (the
cellular network), and packets are lost from time to time. Consequently,
the compositor elements tends to freeze, waiting for both streams to
deliver packets.

Is there a way to ensure a continuous streaming, that is for the compositor
to continue to deliver images even if some (or all) sources do not deliver
images ?

Thank you,

Ben
