- updated parser for 422 specific syntax elements - updated iqitrecon module to handle 422 subtu's. Verified functionality for intra only slices - add support 422 i/o - restrict combinations of output chroma format and internal chroma format allowed. That is, for a given chroma format idc not all output color formats are supported. The output format can now be either same as internal color format or 420p. Test: ./hevcdec Change-Id: I9dbf5c141aceb8ffcbe063aa35856eeed11e3d4f
