javascript - How often does the timeupdate event fire for an html5 video

Question

Learning html5 stuff. It's pretty awesome! Wondering how often the timeupdate event fires.

SIDE NOTE: There are so many interesting possibilities with the js video api. For instance, it might be possible to use ctrl + F to search through video. Run a voice recognition as part of video processing, then create a long key value store with timestamps as keys and words as values, and write a function that searches for instances of those words, but returns timestamps and seeks your video. Anyways, that's just one crazy idea youtube should jump on.

Any help with timeupdate would be awesome!

Answer 1

According to this Bugzilla page:

Firefox fires the timeupdate event once per frame. Safari 5 and Chrome 6 fire every 250ms. Opera 10.50 fires every 200ms.
