Android Question VLCb4a OptionList

[Hackito]

Hello, I am researching the vlcb4a library, I would like to know what are the options that can be added to b4a apart from the normal ones for its execution, the idea is to reduce the delay in videos.
I would also like to know why these options don't work, when placing them I get an error. (java.lang.IllegalStateException: can't create LibVLC instance)

Option List.Add("--File-caching=0")
OptionList.Add("--network-caching=300")

Dim OptionList As List
    OptionList.Initialize
    OptionList.Add("--aout=opensles")
    OptionList.Add("--audio-time-stretch")
    OptionList.Add("-vvv")
    VLCVideoview1.SetVlcOptions(OptionList) 
    StartStreaming
