SaveTube is a JavaScript application that allows downloading videos from video sharing web sites by adding on the bottom right of the page window a menu with all formats and definitions of the video. Below are all supported sites. There is an extra script that gets all video streams from an web page.

The main video sharing web sites on which you can watch videos using SaveTube.

Installation

Usage
Read the following information on how to use the script.

Select the video from the menu or use the options window to select the preferred video definition and container.

Download
Click this button to save the video stream. The script will try to download the video directly when the browser supports this feature. The second icon is shown while downloading. If the browser doesn't support direct download the script will show a link. Click "Link" and the browser will show the open popup window. Some browsers don't have this feature and will open/play the video, for these right click (two-button mouse) or control and click (single-button mouse) 'Link' and 'Save link as'.

DASH
Some sites use DASH streams, which are audio only and video only. These are shown in the videos menu as "Video Only" and "Audio Only". Download both streams and use an external tool to multiplex them. This can be made automatic, enable DASH download support in the options window and the videos menu will show new videos as "Video With Audio". You can download these using a browser protocol and an external script, read below for more details.

HLS
Some sites use HLS streams, which breaks the stream into a sequence of small chunks. These are shown in the videos menu as "HLS". You can download these using a browser protocol and an external script, read below for more details.

Options
Click the vertical dots to open the options window.

Definition (SD, HD etc.)
Select the default (highest) video definition.

Container (MP4, WebM etc.)
Select the default video container.

Open Page Link
Enable/disable auto selection of the page link as the default option in the videos menu. This requires a browser protocol. With this option enabled only the page link is sent to the external application which gets and downloads the streams.

Autosave
Enable/disable video auto-download. If it's on the video download will start when the video page is loaded or when a new video format is selected. This works for "High Definition MP4" YouTube videos or if the browser supports direct download.

Show Save Link
Enable/disable showing the stream link when clicking the download button. When it's on the direct download is disabled.

Save DASH
Enable/disable DASH streams (video with audio) download. This requires a browser protocol and an external application for muxing the audio and video streams

How to download DASH, HLS or any video on Linux and BSD platforms:

1 Create the savetube script, bash example using ffmpeg for HLS and DASH (audio and video streams multiplexing) or youtube-dl for downloading any video

savetube.sh

#! /bin/bash

d="/home/Video/YouTube"
i="$(echo "$1" | sed -e "s/savetube://" -e "s/SEPARATOR/|/g")"
t="$(echo "$i" | cut -d "|" -f 1 | sed -e "s/%20/ /g" -e "s/ +$//" -e "s/^ +//")"
v="$(echo "$i" | cut -d "|" -f 2)"
a="$(echo "$i" | cut -d "|" -f 3)"
f="$(echo "$v" | grep -qi "video/webm\|\.webm" && echo "webm" || echo "mp4")"
if [ "$a" = "" ]; then
   if echo "$v" | grep -qi "\.m3u8"; then
      ffmpeg -y -i "$v" -c copy "$d/$t.$f"
   else
      youtube-dl "$v" -o "$d/$t"
   fi
else
   ffmpeg -y -i "$v" -i "$a" -c copy "$d/$t.$f"
fi

2 Create the savetube protocol file in ~/.local/share/applications

savetube.desktop

[Desktop Entry]
Name=SaveTube Protocol
Exec=/path/to/savetube.sh %u
Type=Application
Terminal=false
MimeType=x-scheme-handler/savetube

Enable protocol:

xdg-mime default savetube.desktop x-scheme-handler/savetube

Test:

xdg-open savetube:http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4

3 Activate the protocol

How to download DASH, HLS or any video on Windows:

1 Create the savetube script, batch example using ffmpeg for HLS and DASH (audio and video streams multiplexing) or youtube-dl for downloading any video

savetube.bat

@echo off
setlocal

set "d=D:\Videos"
set "i=%~1"
set "i=%i:savetube:=%"
set "i=%i:SEPARATOR=|%"
for /f "tokens=1,2,3 delims=|" %%a in ("%i%") do (
   set "t=%%a"
   set "v=%%b"
   set "a=%%c"
)
set "f=mp4"
if not "x%v:video/webm=%"=="x%v%" set "f=webm"
if not "x%v:.webm=%"=="x%v%" set "f=webm"
if "%a%"=="" (
   if not "%v:.m3u8=%"=="%v%" (
      "C:\Program Files\ffmpeg\bin\ffmpeg.exe" -i "%v%" -c copy "%d%\%t%.%f%"
   ) else (
      "C:\Program Files\ytdl\youtube-dl.exe "%v%" -o "%d%\%t%"
   )
) else (
   "C:\Program Files\ffmpeg\bin\ffmpeg.exe" -i "%v%" -i "%a%" -c copy "%d%\%t%.%f%"
)

3.2 Create the savetube registry file, change the script path and execute it

savetube.reg

REGEDIT4

[HKEY_CLASSES_ROOT\savetube]
@="URL:savetube Protocol"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\savetube\shell]

[HKEY_CLASSES_ROOT\savetube\shell\open]

[HKEY_CLASSES_ROOT\savetube\shell\open\command]
@="\"D:\\Scripts\\savetube.bat\" \"%1\""
