[gst-devel] Reduce latency for a MJPEG over UDP multicast pipe

I am trying to reduce the latency for a live video feed from a camera
connected to a video grabber board, compressing using MJPEG and distribute
it over UDP to a computer uncompressing the video and imediately render the
video to the display. Today, using Dual core Inte CPU's and Gbit network,
the total latency for the above scenario is 200 ms (from the light hits the
camera until the pixel illuminates). 

Q: How can I tweek the latency to get it as short as possible. 

Basically, I want to remove all buffers, compress/decompress with such
codecs and rates so it is as quick as possible. Less focus on packet loss
etc..
