Play without delay

[aradeonas]

I am looking for a way to play 2 video in a row without any delay (or very tiny delay) when changing files.
I had 1 mp4 file and with ffmpeg I split it into 2 file and now I want to add them in playlist and play them but I don't want user feel changing video but when I test it because off loading file there is a delay.
I think about stream second file into memory before first file end but I don't know how to do it with VLC.
