Checked video_embed_field admin config screens and see some settings per field but don't see an option to turn on Vimeo API:
Looks like to enable Vimeo API from embed URL, just need to tack on ?api=1. I am able in video_embed_field.handlers.inc:56 to add it like
'defaults' => array(
'width' => '640px',
'api' => 1,
<iframe src=".."...but does render in flashvars below that in html rendered source.
Is there a more configury method of going out it other than editing module code? If that's the way to go about it, would you accept a patch to provide it as an option?
