J.EVC

JPEG based H.261 inspired video codec created as part of my bachelor thesis.

Supports encoding a set of frames both into AVI MJPEG and into a proprietary format designed to emulate the technologies used by H.261.

A semi functional decoder implementation is also included.

Installation

The codec requires Java 20.

$ git clone
$ cd J.EVC
$ mvn clean compile assembly:single
$ java jevc.JVidEncoder

The codec is designed to be used from the command line. The following CLI flags are available:

-i : Input file path
-o : Output file path
-f : Frame rate
-p: Use parallelization
- f: Per-Frame
- g: Per-GOP
- o: Frame Operation
- c: Combination
-m: Compress to MJPEG
-b: Enable benchmarking
-e export: Export benchmark
-d: Create debug frames
-q: Quiet mode
-h: Help

Example:

jevc -i inputFolder -o outputFolder/out.jvd -f 30 -p c -b -e ./benchmark.txt -q

The decoder requires ffmpeg to be installed. Due to it's unfinished nature, no documentation will be provided. Have fun :)
