Fix potential race condition when frame field information SEI arrives before picture timing SEI

  • Overview 0
  • Commits 1
  • Pipelines 2
  • Changes 4

Picture Timing SEI is intentionally not used in parsing of frame field information SEI.

In the existing code retrieving the picture timing SEI from HRD could return a nullptr, when the SEI has not arrived yet. The pointer is dereferenced without checking and passed into frame field info SEI parsing function and used for a consistency check.

This refactoring moves the check after parsing of all SEI messages.
