Comment (by DonMoir):

 This FLV file is much cleaner but still has an initial gray frame when
 played with ffplay since there is no first keyframe. Flash plays it
 without the initial gray frame.

 In all cases that I have tried where this is a problem, my current
 workaround works but not sure if its going to handle all cases.
