Title: Add inputNativeFramerate to options, restore live input functionality #214

By setting inputNativeFramerate:true, buildFfmpegArgs will add "-re" option as first argument to ffmpeg command. See #214 discussion.
From ffmpeg documentation
```
The FFmpeg's "-re" flag means to "Read input at native frame rate. Mainly used to simulate a grab device."
```
