Thanks. DCP is a container for video and audio, and other metadata. I would
like to create
a plugin that decompresses the video, and then streams over an existing
protocol,.

So, my question is: what is the best streaming format to use, once I
decompress ?
For example, are there lossless video streaming formats ? Lossless because
the original
is "visually lossless", so don't want to lose too much image quality.
