> The latency issue may be real or not

The latency is obviously real and obviously unavoidable, since there is
a muxer, a protocol, an OS buffer, a protocol and a demuxer in the chain
that are not necessary with a device. We can try to make it as small as
possible, but there will always be some extra latency.

Plus, ffplay does a lot of things that might interfere with the use,
like keeping the frames in sync with their announced timestamps, like a
-re option that cannot be disabled.

Also, the long-term plan for people who work on lavd has always been to
try to replace SDL in ffplay by lavd. It has not progressed very fast,
but it is a goal. This is a step in the wrong direction.
