Anton Khirnov a6cd154463 h264: move the DPB init/uninit to init_context()/free_context() Currently, the DPB is initialized in alloc_tables() and uninitialized in free_tables(), but those functions manage frame size-dependent variables, so DPB management does not logically belong in there. Since we want the init/uninit to happen exactly once per the context lifetime, init_context()/free_context() are the proper place for this code.		2015-04-29 05:52:57 +02:00
