with some VODs, the clip downloaded doesn't match the timestamp inputted based on what the Twitch player displays at that timestamp.
ex: with VOD 558361951
with argument -start="7 16 20"
this is a frame 10 seconds into the clip downloaded with concat, so it should be 7:16:30
on the twitch player: this frame is actually at 7:16:26
This offset is not constant either, at -start="0 3 10" of the same VOD concat is about 10 seconds ahead of the Twitch player
