* New transcode module:
* $_GET['filter'] determines which torrents should be shown and can be empty/all (default), uploaded, snatched or seeding
* $_GET['target'] further filters which transcodes one would like to do and can be empty/any (default), v0, v2, 320 or all
* Here, 'any' means that at least one of the formats V0, V2 and 320 is missing and 'all' means that all of them are missing.
2013-05-30 08:00:30 +00:00
* 'v0', etc. mean that this specific format is missing (but others might be present).
2013-04-02 08:00:31 +00:00
*
2013-02-27 08:00:35 +00:00
* Furthermore, there's $_GET['userid'] which allows to see the page as a different user would see it (specifically relevant for uploaded/snatched/seeding).
