common_cabac_state

HEVCCABACState* HEVCLocalContext::common_cabac_state

This is a pointer to the common CABAC state.

In case entropy_coding_sync_enabled_flag is set, the CABAC state after decoding the second CTU in a row is stored here and used to initialize the CABAC state before decoding the first CTU in the next row. This is the basis for WPP and in case slice-threading is used, the next row is decoded by another thread making this state shared between threads.
