                            youtube-dl additional arguments



**yt-audio requires either URL or custom argument(s) (or both) as mandatory input(s).**



### Custom Arguments

yt-audio gives user the ability to setup their own custom arguments for managing/synchronizing audio/playlists. Custom arguments can be configured in yt-audio's *(config.ini)* configuration file.



**IMPORTANT NOTE: The user, if required, will have to copy the [configuration file](https://github.com/pseudoroot/yt-audio/blob/development/config.ini) as it is not copied during installation.**



**Unix/Linux Users:**

The default config location is **$XDG_CONFIG_HOME/yt-audio/** directory. In case *$XDG_CONFIG_HOME* is not set, the file can be placed in **$HOME/.config/yt-audio/** directory.



**Windows Users:** The default config location is **C:\\Users\\\\\.config\\yt-audio**



**Setting up custom arguments**



The config file *config.ini* has URL_LIST[] option where users can specify arguments with corresponding URL and (optional) save directory. It's format is as follows:



    URL_LIST = [

                    # "['-short_arg1','--long_arg1','Help Text/Description']::URL::PATH"



                    # PATH (optional) specifies output directory for that particular playlist

                    # PATH should be absoulte directory path

                    # URL: Complete youtube title/playlist URL

                    # These arguments are visible in --help



                    # "['-e','--example1','Example playlist']::URL::PATH",

               ]



URL_LIST takes comma-separated string values. Each string value is formed from 3 components:



- CLI Argument - Argument to register. It is written in form: ['-short_arg','--long_arg','Help Text/Description']

- URL: Youtube playlist/title URL.

- PATH (optional): Path where this particular playlist/title will be saved. Provide absolute PATH here.



All custom arguments are visible in --help [`$ yt-audio --help`]



The default save PATH is **$HOME/Music**.  PATH can be configured by user in config file (OUTPUT_DIRECTORY = \). For playlists, one more directory of \ is created where all playlist records are saved.



#### Keeping track of downloaded titles/playlists

yt-audio has an added feature of keeping track of audio files using **file's metadata**. This removes the requirement of additional archive file to store title(s) info (option provided by youtube-dl).



User can specify any of the two ways to keep track of downloaded titles. (By default, downloaded titles are **not tracked**)



_**Using File Metadata**_



To use file's metadata, pass `--use-metadata` argument to yt-audio. To use metadata everytime, you can set `USE_METADATA = 1` in config file. Metadata method requires following to work:

- `--add-metadata` argument to youtube-dl (`--add-metadata` argument is added by yt-audio by default. If you don't want this, you can re-configure youtube-dl command in config).



_Known limitations of using metadata method_

- I have tried this method with both MP3 and M4A format. MP3 works fine. M4a does not work.



**_Using Archive File_**



To use archive file method, pass `--use-archive` argument to yt-audio. To use archive file everytime with yt-audio, you can set `USE_ARCHIVE = 1` in config file. This will create 'records.txt' file in title's download location.



`--use-archive` flag simply passes youtube-dl's `--download-archive FILE` argument to youtube-dl. You can pass your own filename to youtube-dl as well with `--ytdl-args \"--download-archive FILE\"`. More info about ['--ytdl-args'](https://github.com/pseudoroot/yt-audio#passing-additional-paramaters-to-youtube-dl) argument.



    # Enable metadata

    $ yt-audio --use-metadata [URL/custom_args]



    # Enable archive file - creates records.txt file

    $ yt-audio --use-archive [URL/custom_args]



    # Enable archive file - creates archive.txt file

    $ yt-audio --ytdl-args \"--download-archive FILE\" [URL/custom_args]



_If both metadata and archive file are enabled, archive file method is used_



#### Title/Playlist-specific PATH

User can also specify any arbitrary path for a particular playlist/title. This PATH can be specified as URL::PATH. If PATH is not provided, PATH from config file is used. If no path is present in config, **$HOME/Music** path is used



#### Changing output format

Downloaded file's output format can be specified with `--output-format` argument. [Output Template](https://github.com/ytdl-org/youtube-dl/blob/master/README.md#output-template). Default output format is `"%(title)s.%(ext)s"`



#### Passing additional paramaters to youtube-dl

yt-audio gives user the flexibility to pass additional parameters to youtube-dl directly from command-line. Additional arguments can be provided with `--ytdl-arguments` yt-audio argument. Arguments passed to `ytdl-arguments` are passed as-it-is to youtube-dl.



    $ yt-audio `--ytdl-args \"--download-archive FILE --user-agent UA\"`



**NOTE:** Make sure to escape double-quotes **"** when passing arguments to `--ytdl-args`. Else the arguments passed to `--ytdl-args` will be read as input arguments to yt-audio.



#### Modifying default youtube-dl/helper commands

The commands used by yt-audio can be modified from config file. Unusual parameters might break the program. If the parameter is legit and should have (ideally) worked but it didn't, please [raise an issue](https://github.com/pseudoroot/yt-audio/issues/new).



## Usage Examples



    # Synchronizes/downloads --custom1 and --custom2 custom argument URLs and download specified URL as well.

    $ yt-audio --custom1 --custom2 https://youtube.com/playlist?list=abcxyz



    # Saves playlist to /my/path/p1// and single audio to /some/another/path

    $ yt-audio https://youtube.com/playlist?list=abcxyz::/my/path/p1 https://www.youtube.com/watch?v=abcxyz::/some/another/path



    # Adding additional youtube-dl arguments

    # This will append additional arguments to youtube-dl download command

    $ yt-audio --ytdl-args \"arg1 arg2\" https:youtube.com/abc https://youtube.com/xyz::DIR



    # Different output format

    $ yt-audio --output-format "%(display_id)s.%(ext)s" https://youtube.com/...



## yt-audio defaults

The following commands are used by yt-audio to download and manage audio. The commands are configurable using config file.



**youtube-dl audio download**



    # (-x --print-json -o "$OUTPUT$" $URL$) are mandatory

    $ youtube-dl -x --print-json --audio-format mp3 --audio-quality 0 --add-metadata --embed-thumbnail -o "$OUTPUT$" $URL$



**get playlist/URL info**



    $ youtube-dl --flat-playlist -J $PLAYLIST_URL$



**get file's metadata** (used when downloaded titles are tracked using metadata)



    $ ffprobe -v quiet -print_format json -show_format -hide_banner "$PATH$"



## Limitations

- Keeping track of downloaded tracks works with youtube.com only (for now).
