Video & Audio Muxer Extension

Video & Audio Muxer is an add-on that helps you easily mux video-only and audio-only files and generate a video file with embedded audio in your browser.

It uses the FFmpeg library which is compiled from C and C++ language to JavaScript with the Emscripten project. Emscripten is a source-to-source compiler that can compile native C/C++ codes to JavaScript language.

To work with this add-on, just open the app UI and drag input files (video & audio) in the app UI. Then, press on the - Command - button to insert the mux command and finally press on the - Mux - button to start the job. Once the muxing is done, a preview for the resulting video will be shown and a - Download - button will also appear.

Note 1: if you are familiar with FFmpeg commands, you can enter your mux command in the input field. The - Command - button in the app only inserts a common mux command.

Note 2: the default extension for the output video is set similar to the input video file. You can change this file extension, but please enter a proper FFmpeg command to change the final file extension, otherwise, the FFmpeg engine will not be able to mux the inputs for the chosen output file extension.

Note 3: if you have a feature request, or found a bug to report, please fill the bug report form on the addon's homepage (https://mybrowseraddon.com/video-audio-muxer.html).

Errol Flyne (ID: 0000008507af0362) Voted 5 ★ - Updated 03/06/2021 Very simple, quick, effective, does lossless mux of which many big software couldnt. Very surprising. Cannot mux multiple audio to video for example: just edit audio and synchronize to video stream at another software but mux here in this extension; which i successfully did.
