Description of your issue, suggested solution and other information

When using youtube-dl to download tv-shows, and using output templates (-o), it's problematic for sorting purposes that it's not possible to have a leading zero in the numeric numbering of in particular season_number and episode_number parameters.
This leads to none standard naming of tv shows for indexing purposes and listing in popular media center applications/backends as plex and kodi.

I have a temp solution to this, as to manually specify a 0 in the output template, but that is just odd, as it saves files with 3 digit numbering in season and episode format if epidoe equals 10 or above, se below for my naming:

/%(series)s/%(series)s.S0%(season_number)sE0%(episode_number)s.720p.WEB-DL.H264-YTDL.%(ext)s"

As of now the parameters starts counting at 1, but I would really like to have the possibility to start naming at 01

Please add the possibility to use leading zero in season_number and episode_number parameters.

If anybody has a solution with existing options/parameters/strings, please let me know

Have you even read FAQ?

The special sequences may be formatted according to python string formatting operations. For example, %(NAME)s or %(NAME)05d.

For numeric sequences you can use numeric related formatting, for example, %(view_count)05d will result in a string with view count padded with zeros up to 5 characters, like in 00042.
