command. An additional field "filepath"
that contains the final path of the
downloaded file is also available. If no
- fields are passed, "%(filepath)s" is
- appended to the end of the command
+ fields are passed, %(filepath)q is appended
+ to the end of the command
--exec-before-download CMD Execute a command before the actual
download. The syntax is the same as --exec
+ but "filepath" is not available
--convert-subs FORMAT Convert the subtitles to another format
(currently supported: srt|vtt|ass|lrc)
(Alias: --convert-subtitles)
It may however also contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to [python string formatting operations](https://docs.python.org/2/library/stdtypes.html#string-formatting). For example, `%(NAME)s` or `%(NAME)05d`. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations.
The field names themselves (the part inside the parenthesis) can also have some special formatting:
-1. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a `.` (dot) separator. You can also do python slicing using `:`. Eg: `%(tags.0)s`, `%(subtitles.en.-1.ext)`, `%(id.3:7:-1)s`. Note that the fields that become available using this method are not listed below. Use `-j` to see such fields
+1. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a `.` (dot) separator. You can also do python slicing using `:`. Eg: `%(tags.0)s`, `%(subtitles.en.-1.ext)`, `%(id.3:7:-1)s`, `%(formats.:.format_id)s`. Note that all the fields that become available using this method are not listed below. Use `-j` to see such fields
1. **Addition**: Addition and subtraction of numeric fields can be done using `+` and `-` respectively. Eg: `%(playlist_index+10)03d`, `%(n_entries+1-playlist_index)d`
1. **Date/time Formatting**: Date/time fields can be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it separated from the field name using a `>`. Eg: `%(duration>%H-%M-%S)s`, `%(upload_date>%Y-%m-%d)s`, `%(epoch-3600>%H-%M-%S)s`
1. **Default**: A default value can be specified for when the field is empty using a `|` seperator. This overrides `--output-na-template`. Eg: `%(uploader|Unknown)s`
+1. **More Conversions**: In addition to the normal format types `diouxXeEfFgGcrs`, `j`, `l`, `q` can be used for converting to **j**son, a comma seperated **l**ist and a string **q**uoted for the terminal respectively
To summarize, the general syntax for a field is:
```
The following extractors use this feature:
* **youtube**
* `skip`: `hls` or `dash` (or both) to skip download of the respective manifests
- * `player_client`: Clients to extract video data from - one or more of `web`, `android`, `ios`, `web_music`, `android_music`, `ios_music`. By default, `android,web` is used. If the URL is from `music.youtube.com`, `android,web,android_music,web_music` is used
+ * `player_client`: Clients to extract video data from - one or more of `web`, `android`, `ios`, `mweb`, `web_music`, `android_music`, `ios_music`, `web_embedded`, `android_embedded`, `ios_embedded`, `web_agegate`, `android_agegate`, `ios_agegate`, `mweb_agegate` or `all`. By default, `android,web` is used. If the URL is from `music.youtube.com`, `android,web,android_music,web_music` is used. If age-gate is detected, the `_agegate` variants are automatically added.
* `player_skip`: `configs` - skip any requests for client configs and use defaults
* `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side).
* `max_comments`: maximum amount of comments to download (default all).
