Where did your 1.mp4 and 2.mp4 come from?

I'm download it from Youtube, for example this two video have udta atom:
http://ytapi.com/api/9bZkp7q19f0/direct/18/
http://ytapi.com/api/XSGBVzeBUbk/direct/18/

Code added:
'pasp': read_raw,

• 'udta': read_composite_atom,
• 'meta': read_raw,
  'mdat': read_mdat,
  After this have another problem:
