[PhotoFloat] [PATCH] HTML5 video for PhotoFloat

[Jerome Charaoui]

Hi,

Here's a set of patches which add rudimentary support for video in
PhotoFloat. There's surely a lot of room for improvement, but it works
well enough for me.

Features :

* Requires ffmpeg or libav-tools
* Generates thumbnails
* Transcodes videos to WebM (vp8/vorbis) format
* Downscales to 720p
* Reduces bitrate to 800kbit/s
* Rotates video per metadata indication (useful for mobile-captured video)
* Uses HTML5 <video> for presentation
* Uses Modernizr to validate HTML5/WebM support in browser
