This is the decoder for the cassette video format, a way to turn videos into audio to put them on normal compact audio cassettes.

Just put this somewhere and include it in your html. No installation needed. ¯\_(ツ)_/¯

Check out the included example index.html file. Just instantiate a new decoder object and pass it the canvas you want to use as output in the options object.

The following additional options are also available

hFreq: 225.0,vFreq: 3,overScan: 0.82,hOffset: 0.06525,pulseLength: ( 0.2 / 1000 ),

Timing parameters. These will be output by the encoder script during encoding.

brightness: 1,saturation: 1,

Brightness and saturation of the image. Increase these if the image looks dull or too dark.

lineWidth: 2.5,

Width of the lines drawn on screen. Increase this when your video has low vertical resolution, decrease this if you want more of a scan line effect.

clearInterval: 50,

How often the screen is cleared. Decreasing this will make the image fade faster. Might be needed for higher frame rates to reduce smearing or ghosting.

blend: true,

Disabling this will reduce ghosting but can also make the image look a little dark and less "CRT-like"
