mediainfo.js

This is a JavaScript port of the excellent MediaInfoLib and meant to be run directly in a browser. mediainfo.js was created using Emscripten.

Demo

Try it out in your browser: https://mediainfo.js.org

Build

Make sure the Emscripten tools can be found in $PATH. Something like this will do:

source ~/programs/emsdk_portable/emsdk_env.sh

First you must build the dependencies:

./build-deps.sh

Then build mediainfo.js using:

./build.sh

The resulting files are mediainfo.js and mediainfo.js.mem.

• open
• open_buffer_init
• open_buffer_continue
• open_buffer_continue_goto_get
