Advanced usage

Config

There are 2 properties to configure: api_key and store_dir. At the first time, api_key is empty and you have to set it before using other features.

# set new `api_key`
ytdl config api_key YOUR_OWN_YOUTUBE_API_KEY

# change `store_dir` to new path
ytdl config store_dir /storage/downloads/youtube

# get the current value of `api_key`
ytdl config api_key

# show all
ytdl config

By default, store_dir is being set to /home/{YOUR_USER_NAME}/ytdl_files, you should change it to more appropriate place.

Playlist

Note that this command does not download actual video/audio, but a list of indexed items.

# get playlist metadata into `{store_dir}/{title}.json`
# this file contains a list of videos with their ID and title to download later
ytdl playlist https://www.youtube.com/playlist?list=PLAYLIST_ID

# get playlist metadata into `{store_dir}/my_custom_playlist_name.json`
ytdl playlist https://www.youtube.com/playlist?list=PLAYLIST_ID my_custom_playlist_name

For example if we download the playlist Linux Tips and Tricks

The indexed file looks like below:

Then we will have some powerful ways to download the videos in this list with ytdl video or ytdl audio.

Video

Download a single video file.

# download a video file to `{store_dir}/video/{VIDEO_TITLE}.mp4`
ytdl video https://www.youtube.com/watch?v=VIDEO_ID

# custom name
ytdl video https://www.youtube.com/watch?v=VIDEO_ID my_custom_video_name

To download multi items from indexed playlist, please refer the following arguments:

• --index_file: path to playlist index file (required)
• --since: video ID of the video where you want to start downloading from
• --limit: number of items to download, count from since or the begining of the list
• --prefix_name: to auto naming downloaded file
• --prefix_num: to auto naming downloaded file

Examples:

# download all videos from saved playlist index file above
# these video files will be stored in `{store_dir}/video`
ytdl video --index_file "/path/to/Linux Tips and Tricks.json"

# download 5 videos from saved playlist index file above, since first item
ytdl video --index_file "/path/to/Linux Tips and Tricks.json" --limit 5

# download 5 videos from saved playlist index file above, with prefix name
ytdl video --index_file "/path/to/Linux Tips and Tricks.json" --limit 5 --prefix_name "Linux Tutorial"
# downloaded videos should look like "Linux Tutorial - 1.mp4", "Linux Tutorial - 2.mp4" and so on
# prefix_name will be useful when you want to put these files into an already created list for your different purpose

# download 5 videos from saved playlist index file above, with prefix name and prefix number
ytdl video --index_file "/path/to/Linux Tips and Tricks.json" --limit 5 --prefix_name "Linux Tutorial" --prefix_num 25
# this will be useful for the playlists those are splited to multi parts
# in this case, your serie "Linux Tutorial" had already 24 items before, now count from 25 onwards
# downloaded videos should look like "Linux Tutorial - 25.mp4", "Linux Tutorial - 26.mp4" and so on

# similar to above command, but start from given item
ytdl video --index_file "/path/to/Linux Tips and Tricks.json" --since VIDEO_ID --limit 5 --prefix_name "Linux Tutorial" --prefix_num 25

While downloading video, the stream with highest resolution will be selected.

Audio

This is similar to ytdl video, but only download audio file. While downloading, the stream with highest abr (average bitrate) will be selected.

# download a audio file to `{store_dir}/audio/{VIDEO_TITLE}.mp3`
ytdl audio https://www.youtube.com/watch?v=VIDEO_ID

# custom name
ytdl audio https://www.youtube.com/watch?v=VIDEO_ID my_custom_audio_name

To download multi items from indexed playlist, please refer the following arguments:

• --since: video ID of the video where you want to start downloading from
• --limit: number of items to download, count from since or the begining of the list
• --prefix_name: to auto naming downloaded file

# download all audios from saved playlist index file above
# these audio files will be stored in `{store_dir}/audio`
ytdl audio --index_file "/path/to/Linux Tips and Tricks.json"

# download 5 audios from saved playlist index file above, since first item
ytdl audio --index_file "/path/to/Linux Tips and Tricks.json" --limit 5

# download 5 audios from saved playlist index file above, with prefix name
ytdl audio --index_file "/path/to/Linux Tips and Tricks.json" --limit 5 --prefix_name "Linux Tutorial"
# downloaded audios should look like "Linux Tutorial - 1.mp3", "Linux Tutorial - 2.mp3" and so on
# prefix_name will be useful when you want to put these files into an already created list for your different purpose

# download 5 audios from saved playlist index file above, with prefix name and prefix number
ytdl audio --index_file "/path/to/Linux Tips and Tricks.json" --limit 5 --prefix_name "Linux Tutorial" --prefix_num 25
# this will be useful for the playlists those are splited to multi parts
# in this case, your serie "Linux Tutorial" had already 24 items before, now count from 25 onwards
# downloaded audios should look like "Linux Tutorial - 25.mp3", "Linux Tutorial - 26.mp3" and so on

# similar to above command, but start from given item
ytdl audio --index_file "/path/to/Linux Tips and Tricks.json" --since VIDEO_ID --limit 5 --prefix_name "Linux Tutorial" --prefix_num 25

Downloaded stream will be converted to .mp3 with ffmpeg.
