Streamerz

A playground of video processing examples in Akka streams and Scala (with some Kafka).

It's always been said that the best way to learn a topic through meme engineering. This set of libraries enables all the fun you never wanted to have.

Examples

  1. Rendering your webcam to the terminal in Ascii art

    $ sbt "examples/runMain examples.AsciiWebcam"

  2. Render video (and audio) to the terminal in Ascii Art

    $ sbt "examples/runMain examples.AsciiVideo"

  3. Create a swing video player that can play/pause an mp4

    $ sbt "examples/runMain examples.VideoPlayer"

  4. Run a web server that streams your webcam to web browsers in Ascii art

    Dependencies:

    $ brew install kafka 
$ brew install zookeper

    Run in 3 terminals:

    $ zkServer start
$ kafka-server-start.sh /usr/local/etc/kafka/server.properties

$ sbt "examples/runMain examples.asciiweb.feed.AsciiImageProducer"

$ sbt "examples/runMain examples.asciiweb.ws.Main"

You can now check your webcam/drone feed as an Ascii-art animation on http://localhost:8080
