That sounds feasible, yes. However streaming MP4 is generally not
supported unless it's fragmented MP4. You'll have some problems with
that and it will also involve some delay.

Is this really a MP4 container and not just raw h264? Can you somehow
output raw h264 or everything a container that is better for streaming
(e.g. mpegts)?
