I have an iframe with a video, for example:
<iframe src="http://player.vimeo.com/video/18150336" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
The source won't always be vimeo, it can be YouTube, BrightCove, Hulu etc etc.
Is there a way to use jQuery/JavaScript to "seek" to a certain time in the video? For example, if I wanted to get to 3:41 inside of a video could I write code to automatically seek to that time w/o API access to the sites providing the video?
Sure. You can use VideoJS. You may have a hard time getting control of the iFrame as you put it. You can embed various video hosting sites' video with VideoJS, supposedly.
<script>
VideoJS.DOMReady(function() {
var player = VideoJS.setup("current_video");
player.play();
player.currentTime(666);
});
</script>

Unless your website also has the host, protocol and port of http://player.vimeo.com, you can not run any code on the iframe's document.
Unfortunately, not always. There is no single solution to seek a time in a Flash video if you don't know what the source of the video is.
If you ever encounter HTML5 video, you can try this: Start HTML5 video at a particular position when loading?
That iframe will give you trouble, however in general you can do this without a library.
// get the video element
let video = document.getElementsByTagName('video')[0]
// jump it to a specific time
video.currentTime = 10 // the number of seconds you want it to be at
