Compile FFmpeg on Ubuntu

This guide supports Ubuntu Precise Pangolin 12.04, Ubuntu Oneiric Ocelot 11.10, Ubuntu Natty Narwhal 11.04, and Ubuntu Maverick Meerkat 10.10. Separate guides are available for Ubuntu Lucid Lynx 10.04 and Ubuntu Hardy Heron 8.04. This guide will enable several external encoding and decoding libraries: libfaac (AAC encoder), libfdk-aac (AAC encoder), libmp3lame (MP3 encoder), libopencore-amr (AMR encoder/decoder), librtmp (for additional RTMP protocols), libtheora (Theora encoder), libvorbis (Vorbis encoder), libvpx (VP8 encoder/decoder), and libx264 (H.264 encoder). These are optional and may be omitted if desired. This guide will also install many filters (see the filter list in the [Filtering Guide](https://ffmpeg.org/trac/ffmpeg/wiki/Fi

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

	=Navigating=
	visit('/projects')
	visit(post_comments_path(post))

	=Clicking links and buttons=
	click_link('id-of-link')
	click_link('Link Text')
	click_button('Save')
	click('Link Text') # Click either a link or a button
	click('Button Value')

	literally always have to look up the meaning of :limit in migrations when it comes to integer values. Here's an overview. Now let's memorise it (oh, this works for MySQL, other databases may work differently):

	:limit Numeric Type Column Size Max value
	1 tinyint 1 byte 127
	2 smallint 2 bytes 32767
	3 mediumint 3 byte 8388607
	nil, 4, 11 int(11) 4 byte 2147483647
	5..8 bigint 8 byte 9223372036854775807

	Note: by default MySQL uses signed integers and Rails has no way (that I know of) to change this behaviour. Subsequently, the max. values noted are for signed integers.
