 ### Motivation
 The motivation behind this project is that streaming with a feature-rich, bleeding-edge client such as OBS and FMLE is very CPU intensive even on reasonably capable machines.  In situations such as live code streaming, where the broadcast is an auxiliary concern, there is more utility in reserving those extra cycles for primary development tasks.
 
-A command-line solution is the obvious choice for such scenarios but obviously lacks real-time control and preview.  This project was created to mark a reasonable balance between headless performance and a graphical feature set.  Initially a simple ffmpeg command-line launcher GUI; it has since become a gStreamer native library implementation.

+Also, the ffmpeg bash script that AvCaster was originally conceived to wrap is in [this gist](https://gist.github.com/bill-auger/9480205a38d9d00d2fa3) if an ultra-lightweight command-line webcasting tool is more suitable.  It is capable of recording to file or streaming to an RTMP server with screen capture, webcam, text overlay, and stereo audio.  It requires some manual configuration o/c, but is approximately twice as nice.
