Video creation and manipulation in Clojure
Currently you can use it to encode H264 video from a sequence of image frames. Not much support for anything else yet.
Telegenic is a wrapper for the pure-Java JCodec library for video encoding / decoding. You may need to manually install the jcodec-javase dependency into your local maven repository, as this is currently not available on Maven Central. You can download the artifacts here:
(use 'telegenic.core)
(use 'mikera.image.core :as img)
(let [;; A green frame
f1 (img/new-image 100 100)
_ (img/fill-rect! f1 0 0 100 100 java.awt.Color/GREEN)
;; A green frame
f2 (img/new-image 100 100)
;; A sequence of frames. Frames can be re-used for efficiency.
frames (concat (repeat 20 f1) (repeat 20 f2) (repeat 20 f1) (repeat 20 f2)))]
;; finally encode everything into an mp4
(encode frames {:filename "out.mp4"})
