Description

In Multilayer bitstream SPS may contain no PTL information.
In this case decoder issues warnings like:

  • "Warning: Profile set to none or unknown value"
  • "Warning: Level set to none, invalid or unknown value"

For Multilayer OLS PLT should be extracted from VPS.

Also, when vps_pt_present_flag[i] = 0 decoder should follow Spec:

When vps_pt_present_flag[ i ] is equal to 0, the profile, tier, and general constraints information for the i-th profile_tier_level( ) syntax structure in the VPS are inferred to be the same as that for the ( i − 1 )-th profile_tier_level( ) syntax structure in the VPS.
