@ -150,6 +150,8 @@ # OUTPUT TEMPLATE
|
||||
- `ext`: The sequence will be replaced by the appropriate extension (like flv or mp4).
|
||||
- `epoch`: The sequence will be replaced by the Unix epoch when creating the file.
|
||||
- `autonumber`: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.
|
||||
- `playlist`: The name or the id of the playlist that contains the video.
|
||||
- `playlist_index`: The index of the video in the playlist, a five-digit number.
|
||||
|
||||
The current default template is `%(id)s.%(ext)s`, but that will be switchted to `%(title)s-%(id)s.%(ext)s` (which can be requested with `-t` at the moment).
