    VLC Lyric Control (VLyriC)

    Control live text overlay(s) over a live video feed or file using VLC.

    VLC Lyric Control (VLyriC) is a light-weight utility built to work with VLC 2.0.8 in order to display and control live text overlay(s) on top of a video feed or file that is being played by the instance of VLC that VLyriC is connected to.

VLyriC is geared towards individuals who need to broadcast a live video feed of a large meeting or conference (primarily LDS Stake Conferences), and include a text overlay to display names/titles of those speaking and/or lyrics of songs to be sung during the meeting or conference. VLyriC depends on the .NET Framework 4 (either the Client Profile or Full frameworks are OK), and has been run on Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 8.1. This project is based on the original VLyriC written by Charles Boling (http://ebs.boling.us/apps/vlyric/).
