Encoding Video

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

//To be used on shadertoy.com
//Uses the image at iChannel0 and warps it into polar coordinates
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    vec2 relativePos = fragCoord.xy - (iResolution.xy / 2.0);
    vec2 polar;
    polar.y = sqrt(relativePos.x * relativePos.x + relativePos.y * relativePos.y);
    polar.y /= iResolution.x / 2.0;
    polar.y = 1.0 - polar.y;

About compression

Audio compression is used to reduce the dynamic range of a recording. Dynamic range is the difference between the loudest and softest parts of an audio signal. It was originally used to guard against defects when cutting wax and vinyl phonograph records, but generally became useful as a way of increasing the loudness of an audio recording without achieving distortion.

The goal of most compression applications is to increase the amplitude of the softest parts of a recording, without increasing the amplitude of the loudest parts.

Compressor anatomy

Compressors generally all have the same conceptual parts. However, not all compressors present variable controls for all parts to the user. If you don't see all of your compressor's controls here, there's a chance it either has a fixed value (and no control), or is named something else:

OEmbed Liquid Tag for Jekyll

This is a simple liquid tag that helps to easily embed images, videos or slides from OEmbed enabled providers. It uses Magnus Holm's great oembed gem which connects to the OEmbed endpoint of the link's provider and retrieves the HTML code to embed the content properly (i.e. an in-place YouTube player, Image tag for Flickr, in-place slideshare viewer etc.). By default it supports the following OEmbed providers (but can fallback to Embed.ly or OoEmbed for other providers):

• Youtube
• Flickr
• Viddler
• Qik
• Revision3
• Hulu
• Vimeo
