| Summary | 0000183: Regarding qp_per_matrix and qp_rem_matrix | ||||
| Description | In streams with multiple sequence the decoder crashes after the second sps is activated as the qp_per_matrix and qp_rem_matrix contain junk. This occurs because :- 1. On encountering a new sps activate_sps() is called 2. In activate_sps() init_frext() is called where the init_qp_process(img) is called. In this function the qp_per_matrix and the qp_rem_matrix are assigned values. 3. After returning from init_frext() the init_global_buffers() is called. 4. In this function the global_init_done = 1 so free_global_buffers() is called. if (global_init_done) { free_global_buffers(); } 5. In the free_global_buffers() both the qp matrices are freed by the function call free_qp_matrices(); 6. Hence when we decode the next slice both the qp_per_matrix and qp_rem_matrix contain junk. | ||||
