Your whole description makes no sense, are you streaming mpeg-ts or AVI or?
Also where does the delay come from? Have you tried getting the cam out of the loop by streaming from a file? Getting VLC out of the loop by using a file it transcoded before directly?
Either way MPEG-TS is a horrible format for low-delay streaming, it does not contain sufficient data in the headers so a lot of parsing and reading additional data must happen.
There's an option for FFmpeg to make it stop reading in so much before going on and start the actual transcode.
