Summary0001798: Comply with (or at least warn about deviations from) SMPTE Bv2.1 application profile
Description

Things to think about / investigate

  • [6.1] Everything should be SMPTE (ST-429-2); default to SMPTE and warn about Interop
  • [7.1] Hint about or hide behind "advanced" setting: all 30fps, 50fps, 60fps; everything but 24/2D in 4K.
  • Should there be a single "conform to SMPTE Bv2.1" checkbox? Allow, warn, disallow?
  • Does asdcplib do the MIC [10.1]?
  • Check other JPEG stuff in [10.2.1]
  • Audio stuff in [10.3.2]
  • Timed text stuff in [10.4]

Missed out [8.6.1] as it doesn't really say anything.

On going through Bv2.1 I got up to and including 10.1 ("encryptIon") on page 13. Next bits are HMAC/MIC, J2K details, channel assignments, some small bits with timed text, sign language video-as-PCM.

Looks like inspection of the J2K for verification is not easy to do with libopenjpeg.

Need to go through Bv2.1 again checking DoM and libdcp verify support is "good enough" for 2.16.0.
