Bitstream feature name: Resolution change in SPS

Bitstream feature description:
rep_format( ) structure in VPS signals picture width & height, chroma format, bit depths and conformance crop window parameters.
For base layer (layer_id = 0) or independent non-base layer, SPS signals picture width & height, chroma format, bit depths and conformance crop window parameters. 
These parameters can override values signalled by VPS rep_format( ).
The bitstream has 2 rep_format( ) structures signalled in VPS Extension. SPS for layer 0 signals new resolution.

- OLS_1 -   Layer: 0, PTL Idx: 1 (Main 3.1)
            Layer: 1, PTL Idx: 2 (Scalable Main 4)

Number of layers: 2

Profile, Tier, Level information: Num PTL = 3
