[Android] understanding vlc and reduce latency

[shiv garg]

i am new to vlc project. we are using vlc to display feed from three ip cameras on an android tab. but there is lag of 3s . My work is to reduce the lag to below 1s. i tried reducing the network catching it solved the issue little but did not completely. so i have to understand the vlc source code so that i can lay down a framework to comment exactly how much latency is there in the whole pipeline. i cannot debug the source on android. kindly guide me with the way how should i understand the source code of vlc media player and how i can reduce the latency in rtsp streaming... 
but kindly guide me through how i can understand code of vlc media player. so that i can contribute towards it in future.
