    http://blog.add0n.com/2015/05/11/a-guide-to-video-and-audio-conversion-using-ffmpeg.html

  3. Is it possible to use Media Converter's conversion capabilities in other extensions?

    Yes, Media Converter has a built-in API system which makes it possible for other Firefox extensions to use it directly, https://github.com/inbasic/media-converter/blob/master/connect.md. There is no need to call the UI. You can send conversion commands directly from a Chrome enabled JavaScript environment. In fact, the actual Media Converter's UI uses these API calls to perform all the conversions.

  4. I am not using Media Converter everyday, is there a way to move the icon from Firefox's toolbar to free up space?

    Yes! It is recommended to move Media Converter's icon to the menu-panel. Read a Comprehensive Guide to Firefox Customization for details.

  5. How does the extension do the conversion/muxing?

    The extension uses the powerful FFmpeg to do all the conversion requests. Basically it is a UI over this command line tool.

  6. What are the supporting conversion methods?

    The conversion window supports drag and drop of either local file(s) or a downloadable link. So basically you can convert multiple files at once only if they are locally available.

  7. Why does the extension ask me to download FFmpeg?

    This extension requires FFmpeg audio and video converter to perform all its conversions. Basically it is only a wrapper to the command-line FFmpeg media converter. If you already have FFmpeg in your system, most likely the extension will find it and use it. If not you can point the extension to use the installed FFmpeg. If you don't have FFmpeg though, then you have two options. Either let the extension to install it for you or manually get it from https://www.ffmpeg.org/download.html and then ask the extension to use the downloaded executable.

  8. How can I abort the current conversion?

    If for any reason you would like to abort the current operation, you need to force-stop FFmpeg process from your OS activity monitor. Next version will implement this feature in the UI.

  9. Media Converter doubles the length of original file after conversion. Is there any way to fix this?

    Most likely there is something wrong with your FFmpeg executable. Try to get a fresh copy from https://www.ffmpeg.org/download.html and point the extension to use the new executable.

  10. When I try to point the extension to use FFmpeg on Mac or Linux, the actual binary path is selected instead of the symlink. How can I fix this?

    This is a bug with Firefox open file module. There is no easy fix for it. However, you can follow the instruction on https://github.com/inbasic/iaextractor/issues/36 to manually set the correct path for FFmpeg executable.

  11. When the extension combines a video and an audio files together into a single file, does it re-encode the files or the quality is intact (there is no re-encoding)?

    No, the process does not involve re-encoding, thus the quality of both video and audio streams is maintained.

  12. I'm trying to extract audio from a video file, but whenever I do, I get this error: ffmpeg.js --> toAudio --> could not predict output format. Any workaround?

    This mostly happens when you drop a download link to the conversion window. Make sure the link you dropped is actually a downloadable stream, not just the link to a page containing the video file. If you are not sure, first download the file manually, then drag and drop the downloaded file to the conversion window.

  13. How can I add or remove the toolbar button in Firefox?

    To add/remove the toolbar icon right-click on a free space in your Firefox toolbar and select "Customize...". Now you can drag and drop the button to a new position.

  14. Media Converter's icon suddenly disappeared from my Firefox browser. Is there any fix?

    For an easy fix, try the Media Converter in a clean profile, http://blog.add0n.com/2016/01/30/how-to-use-firefox-profile-manager.html. If you have many extensions on your current profile and dont wish to switch to a new profile, you need to debug the extension and report the bug in the GitHub page to find the problem and hopefully address it on the next release. To do so, close all your Firefox windows. now open a single window, and then open Error Console (Ctrl + Shift + J in windows and Command + Shift + J) in Mac OS. There must be an error there preventing the Meda Converter from initiating. Take an screenshot of the console and share it in GitHub as a new bug.

  15. How to install Media Converter in your Firefox?

    To install Media Converter, head to Mozilla Store and click on "Add to Firefox" button.

  16. How to uninstall Media Converter from your Firefox?

    To uninstall Media Converter go to Firefox -> Add-ons -> Extension Name, then press Uninstall button.

  17. Is it possible to change the sample rate of the MP3 converter?

    Yes, you can change the sample rate of the converter by changing the command line to -y -i %input %quality -ar SAMPLR_RATE %output.mp3 where SAMPLR_RATE is the preferred rate (like 22050 or 44100).
