I've finally gotten round to releasing a couple of updates to the arc_youtube plugin for Textpattern.
arc_youtube v1.0 sees some relatively big changes to the way the plugin works; mainly due to the move from the old Youtube embed code to the new iFrame version. As a result a load of parameters for the plugin have been dropped and new ones added according to what is available. The new embed code no longer allows for the player's colours to be fully customisable so color1 and color2 parameters have been dropped and the new color and theme parameters have been added. Other new parameters include start that lets you specify the starting point of the video.
Anyone wishing for a simpler upgrade can install v0.4 which includes some bug fixes. The old parameters remain the same (see the plugin's help documentation).
Both versions now support Youtube's youtu.be short URLs as the video parameter and now will be auto-enabled on install.
You can get the latest releases from the plugin's page.
