• Online downloader services are scattered all over the Internet. The problem is that you have to manually copy the URL of the video. FastestTube is an excellent add-on allowing users to download videos directly from YouTube.

A while back YouTube started to use DASH format (Dynamic Adaptive Streaming over HTTP) for 1080p and 480p videos. DASH is an adaptive bitrate streaming technology where a multimedia file is partitioned into one or more segments and delivered to a client using HTTP. Now instead of single multimedia file, there are at least 2 separate files: one with the audio line, the other — video. At the moment FastestTube can’t merge them automatically. However we added the facility to download both audio/video files so you can combine them later into a single one with ffmpeg or similar tools.

Custom filename is not yet supported, therefore both audio/video files are downloaded as 'videoplayback'. The audio file has the mime-type: 'audio/mp4' and therefore should have the file extension: 'm4a' or 'mp4' but some browsers may require you to add the extension manually.

For parents who have children, these video downloader software are also what you need because most children are visual learners, and by downloading videos into your devices, such as a nursery rhymes, this would eventually make your child enjoy while learning. Sadly, FastestTube is on their blacklist. As they told new security measures are necessary to 'protect Chrome users from malicious threats', but in reality they are banning our extension for giving users a chance to download videos from YouTube. Enforcing these new policy, Google is only depriving its users of many handy tools, including. There is an app for iphones and other apple products (not sure about other brands) called Better Tube. Keep in mind, this app costs $9.99 to be able to download videos, but you can download as many as your iphone/ipad/ipod can store, and you can c.

Once you have downloaded both video and audio files (‘videoplayback.mp4’ and ‘videoplayback.m4a’ respectively), here’s how you can merge them into a single file:

• Download and install ffmpeg.
• Open a Command Prompt window in your downloads folder and run the following command
  • In case of MP4 format (all, except 1440p 60fps & 2160p 60fps):
  ffmpeg -i videoplayback.mp4 -i videoplayback.m4a -c:v copy -c:a copy output.mp4
  • In case of WebM format (1440p 60fps and 2160p 60fps):
  ffmpeg -i videoplayback.webm -i videoplayback.m4a -c:v copy -c:a copy output.mkv
• Wait until ffmpeg finishes merging audio and video into a single file named 'output.mp4'.

VLC media player allows you to watch the video with an external audio track.

YouTube uses an uncommon codec called Dash for their audio files and some media players can't play it. You can convert the Dash audio format to a more common format using one of the many online services available like this one or that one.

Otherwise you can always manually convert the Dash audio file to any format with ffmpeg. To do so, you need to know your audio's bitrate, which was shown in the download menu. If you don’t remember the bitrate you can check it by running
ffprobe INPUT_FILE
in the Command Prompt window. Just replace INPUT_FILE with the downloaded audio file name.

Then you need to convert the bitrate from kbit/s to bit/s. To do so just add three zeroes after the bitrate (ex.: 128 kbit/s audio would be 128000 bit/s). Thereafter you need to execute the following command in the Command Prompt window:
ffmpeg -i INPUT_FILE -ab BITRATE -vn OUTPUT_FILE

• INPUT_FILE — a path to the downloaded audio;
• BITRATE — audio bitrate (only the numeric value is allowed);
• OUTPUT_FILE — new file's name. Note that you have to use a valid audio format extension for the output file (like .mp3 or .m4a).

Example:

For some qualities Youtube provides videos only in WebM format. WebM could be converted in MP4 with the following ffmpeg command

Please note that such a conversion may take a very long time.
