[vlc-devel] capturing state of module chain at runtime

[Thomas Brouckaert]

Hey Walt,

Run vlc with the option -vvv for debug information.
You will see in the log every time VLC is looking for a module and which
module VLC picked.
This should give you a pretty accurate view of the current modules.

I hope this answers your question.

Regards,

Thomas
