You are using tcp so worst case you'd have drop the connection or feed
another cluster.

You are about to get into the lands of the segmented formats.

The current segment muxer in Libav originates from my early try to bake
something like hls but using webm and some lines of javascript, never
advertised it a lot since it was just an experiment though.

If you set the size and time to be large enough you won't see many problems.
