- Add support of several output type
* legacy:
From the 0.0.* branch, works with ffmpeg > 0.5
* h264:
Same as legacy but use x264. Faster encoding and smaller file size.
Require a recent ffmpeg
* h264_overlay:
Display both the slides and the speake. Use x264, encoding is much
slower than h264 (~10x)
- Removed PIL dependency
- Fix some encoding issues
- Fix broken slide download due to a markup change
