./vlc movie.avi --sout="#transcode{aenc=dummy,venc=stats}:std{access=http,mux=dummy,dst=0.0.0.0:8081}"

stats: Initial import of a stat oriented module. Use with /vlc --ignore-config -I dummy -vvv movie.avi --sout="#transcode{aenc=dummy,venc=stats}:std{access=http,mux=dummy,dst=0.0.0.0:8080}"

It is much more efficient regarding latency as it doesn't bufferize more than needed, and let the module access take care of that eventually.

Enable with --use-stream-immediate. We may want to default it.

Note: --use-stream-immediate will be only effective on access that don't provide pf_block() for now. This is because I didn't benchmark against the Block method.

Here the gain that I did measure is about 200ms (less latency) when using the http access on a loopback.

Better comment them fully, if you are too lazy to report upstream

wanting to have fun with transcode / audio / filter chains)

less than that of the planar version (uses nearest neighboor instead of
interpolated colors)

Fixes a bunch of crashes at exit.

It needs to be done by the parent (VLM or playlist)
