Why is it doing that? Is it doing non-blocking writes to ’stdout’? If so,
then it probably shouldn’t. If you do blocking writes to ’stdout’, and nothing
is currently reading from the other side, then your encoder will just block
until the other side needs data.
It does non-blocking writes because otherwise everything else stalls.
We're only sending one of the streams to live555, the other streams
can't stop just because no-one is pulling the RTSP stream.
