Thanks, yes. I would like to create the following components:

1) read DCP file from disk and demux using asdcplib, a separate library
using openssh
2) store uncompressed video and audio in container
3) stream using RTSP protocol to VLC client

I chose RTSP because I would like the VLC client to be able to seek,
rewind, ff, pause.

I would prefer raw video, as long as VLC client supports it.
