Default (Feature Request) Manual Audio/Video Sync

hi
I would like to request a option for manual audio video sync as present in vlc in pc and bs player or dice player in android.. but unlike bs player (limits to 3 sec) or dice player (limits to 1 sec) with manual entering of time... as some of the videos from youtube or other sites like daily motion come with faulty a/v sync an android plays them as it is without correctin them.. so if its possible pls add this feature
