As a plugin API, Frei0r's main emphasis is on simplicity, to round up the most common video effects into simple filters, sources, and mixers that can be controlled by parameters. Frei0r plugins can be shared by many host applications, avoiding duplicate efforts by different projects. Frei0r is not meant as a competing standard to more ambitious efforts trying to satisfy the needs of many different applications and more complex effects, as it doesn't provides things like an extensive parameter mechanism or event handling.
Release Notes: This release fixes several major bugs in existing plugins and adds 20 new plugins, some of them optional with a dependency on the Cairo library. The new filters are: IIRblur, Vignette, Keyspillm0pup, Timeout, Posterize, Dither, Spillsupress, Emboss, Colgate, RGBNoise, Colorize, Softglow, ColrHalftone, Sigmoidaltransfer, Colortap, Cairogradient, Cairoimagegrid, and Medians. There are also two new mixers: Cairoblend and Cairoaffineblend.
