  • 4. How does Video Converter addon work?

    This addon uses the free and open source conversion library called FFmpeg. FFmpeg is originally written in C and C++ languages. But within the browser, only JavaScript language is accepted. Therefore, this addon uses a compiled version of FFmpeg library in Javascript language. The compiled version is the result of Emscripten compiler. Please read this Wikipedia page to get more info about Emscripten compiler. All the original FFmpeg commands are also accepted in this Javascript compiled version. However, not every codec is supported yet. So please check for available codecs before using the addon. It is also important to note that, because this library is based on Javascript, it may NOT have the same performance as the C and C++ versions. Since it runs in the browser and has less resources comparing to the native C Ffmpeg application. But, according to our tests it is useful for ordinary usage.

  • 10. Can I also convert audio formats with this addon?

    This addon is specifically designed for video file formats. However, a limited number of audio formats (i.e. mp3) may also be supported. For audio conversion, you need a separate addon.

  • 11. Does this addon has comparable performance to native FFmpeg applications?

    No, since this addon runs FFmpeg in the browser, it runs slower than the native FFmpeg applications/library. However, using the addon is very easy (in fact much easier than the native FFmpeg command-line tool). Simply add it to your browser and it starts to work without any additional plugins. The native FFmpeg library is rather hard to use and may be difficult to install on different operating systems. But this addon is supported on all major browsers and platforms. Please note that, for very large video files, you still need the native FFmpeg library. This addon is only suitable for simple conversions (rather small video files).
