  • The interlacing information doesn't seem complete to me. How do you know which field(s) you have in any give packet, for example? How do you distinguish between a 25Hz shutter and a 50Hz shutter? Field order switching? Mixing with uninterlaced data?
  • There doesn't seem to be any handling of variable frame-rate data, or a specification for a timebase for the granulepos.
  • The identifier seems a little short. You'd get false positives if somebody wanted to use a "YUVx" format, for example.
  • Is the aspect ratio the pixel aspect or the frame aspect? --Gumboot 03:00, 9 Nov 2005 (PST)
