mini-decoder.js

Simple raw video frame decoder for JavaScript using openh264 and libvpx libraries.

This work is based on https://github.com/kazuki/video-codec.js.

Build

We use Docker to build:

docker build -f Dockerfile -t builder .

Get the build artefacts:

docker run --rm -ti --init -v $PWD:/opt/output builder

The Docker container will copy openh264_decoder.js, and libvpx_decoder.js into your current working directory.

Install

Simply copy mini-decoder.js, openh264_decoder.js, and libvpx_decoder.js into your project. Then, you can feed raw frames into it using

decodeAndRenderH264('videoFrame' /*your canvas*/,
                    640 /*frame's width*/,
                    640 /*frame's height*/,
                    rawData /*frame's rawData*/));

decodeAndRenderVPX('videoFrame' /*your canvas*/,
                   640 /*frame's width*/,
                   640 /*frame's height*/,
                   rawData /*frame's rawData*/),
                   'VP80' /*if rawData is encoded using VP8, otherwise 'VP90'*/);
