[FFmpeg-user] Rtsp overlay and relay

I am using a Samsung exynos and my plan was to overlay text on live rtsp for an IP camera and sink it to another rtsp server so the h264 feed will have text from a file overlayed 
My question is can I get the overlay or filter on with the least amount i demuxing and decoding so I can reduce the latency as mush as possible 
I will use the codec copy but is there a way to get around the formatting and codecs as both input and output are the same
