object frame has the following properties:
width - frame width height - frame height pts - actual presentation timestamp, in seconds. lum_data/u_data/v_data - node buffers containing the actual frame data (not copied, shared with the c++ core)
next
Signature: number next()
Get the pts of the next frame.
eof
Signature: boolean eof()
Check if the file decoding is ended (and all the frames have been decoded)
seek
Signature: boolean seek(number position)
Seek to a given PTS, in seconds.
length
Signature: boolean length()
Get the total length of the loaded video (in seconds).
get_direction/set_direction
