Download videos

Play the video in VLC
On VLC, check Tools -> Codec information and find a URL there
Open the URL on a browser. Right click the video and choose to save the video.

The method works for youtube and vimeo videos.

Firefox/Chrome add-on

3 Easy Ways to Download YouTube Videos in Ubuntu and Other Linux Distributions

Video DownloadHelper add-on works fine when I test it on Firefox and Chrome. I need to install an app Video DownloadHelper companion app (the source code is on Github) in order to use the extension. It saves the videos to ~/dwhelper folder.

Youtube-dl

https://rg3.github.io/youtube-dl/download.html
- It is based on Python2. Ubuntu 20.04 does not include python2.
What are the Best Youtube Video Downloader for Ubuntu
The Best YouTube Downloader on Linux: youtube-dl, Minutube, ClipGrab

4 Best open source & free YouTube Downloader for Ubuntu Linux

# which youtube-dl
# sudo rm /usr/bin/youtube-dl

# Method 1.
sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

# Method 2.
sudo pip install --upgrade youtube_dl

# Log out and log in
youtube-dl --version
# 2019.01.02

# Download as an mp4 
youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/mp4' URL
# Download a youtube playlist
youtube-dl -f mp4 --yes-playlist URL

For videos with 1080p resolution, youtube-dl will download 720p by default. To download 1080p, see this post

# show the available resolutions
youtube-dl -F XXX
# download the desired resolution
youtube-dl -f 137+141 XXXX 
# Note the two numbers 137, 141 is case dependent. They could be 137 & 140.
youtube-dl -f 22 XXX
# if the format 22 is mp4. If I do not specify the format, the mkv file will be downloaded
# But playing mkv file tends to be stuttering with VLC.

~~This assumes Ubuntu has installed avconv; otherwise video(mp4) and audio(m4a) files will be downloaded separately.~~ To install avconv, install the libav-tools package. Note that libav-tools was replaced by ffmpeg in Ubuntu 18.04.

                                          Doesn't work with -H -D
     -D, --ext-menu                       Use external menu(default dmenu) instead of fzf 
     -H, --choose-from-history            Choose from history 
     -x, --clear-history                  Delete history
     -m, --audio-only   <search-query>    Audio only (for music)
     -d, --download     <search-query>    Download to current directory
     -f                 <search-query>    Show available formats before proceeding
     -a, --auto-play    <search-query>    Auto play the first result, no selector
     -r  --random-play  <search-query>    Auto play a random result, no selector
     -n, --video-count= <video-count>     To specify number of videos to select with -a or -r
     -l, --loop         <search-query>    Loop: prompt selector again after video ends
     -s                 <search-query>    After the video ends make another search 
     -L, --link-only    <search-query>    Prints the selected URL only, helpful for scripting

     --previews=       <left/right>      the side of the screen to show thumbnails
     --upload-time=     <time-range>      Time range can be one of, last-hour, today, this-week, this-month, this-year
                   You can also put the filter as it's own option eg: --today
     --upload-sort=     <sort-filter>     The filter to sort the videos can be one of, upload-date, view-count, rating

     --filter-id=       <filter>          The id of the filter to use for video reults
                   A filter id can be found by going to youtube searching, filtering how you want
                   Then taking the value of the &sp= part of the url
                   Filters may not work especially when the filter sorts for non-videos
                   In addition this overrides any filter provided through options
                   Example: ytfzf --filter-id=EgJAAQ minecraft
                   This will filter by livestream

     --update                             clones the latest commit and installs it
                   on Arch ytfzf is available in the AUR
  Use - instead of <search-query> for stdin

  Option usage:
     ytfzf -fDH                           to show history using external 
                                          menu and show formats
     ytfzf -fD --choose-from-history      same as above
