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 (top section). Then, press the - Command - button to insert the mux command, and finally press the - Mux - button to start the job. Once the muxing is done, a preview of the resulting video will be shown and a - Download - button will also appear. To switch the app theme to dark, please press the moon icon next to the - Mux - button.

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 file is set automatically based on the input video and audio formats. However, 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 out the bug report form on the addon's homepage (https://mybrowseraddon.com/video-audio-muxer.html).
