requestVideoFrameCallback polyfill

[wlcx]

requestVideoFrameCallback isn't available in !chrome currently, so add a polyfill

The current box only seems to update when the video is playing - so if you step through frame-by-frame or jump to a specific timecode, current stays at the value of when you stopped

Good point. Have added a seeked listener which seems to be good enough?

Just noticed the current time also appears to be one frame off. Marking an in or out is accurate, but current is consistently 1 frame ahead. Can't figure out where its coming from tho

@rrah so I generated a test video (only at 25p admittedly) with BITC, and I noticed the converted video seemed to have 1 extra frame on the end. otherwise it seemed pretty much bang on to me

At least for me, if I load a video, Current starts at 00:00:00:01. If I mark an In or Out, it's recorded as 00:00:00:00, but with Current still being 00:00:00:01
