Tell me what is wrong here:

drivers/frame_provider/decoder/h264_multi/vmh264.c

          	    rdata32 = READ_VREG(VDEC_PIC_QUALITY_CTRL);
          #ifdef DEBUG_QOS
          	    pr_info(" [Picture %d Quality] After Read : VDEC_PIC_QUALITY_CTRL : 0x%x\n",
          			pic_number, rdata32);
          #endif
          		/* reset all counts */
          	    WRITE_VREG(VDEC_PIC_QUALITY_CTRL, (1<<8));
          	}
          }
          
          static int get_dec_dpb_size(struct vdec_h264_hw_s *hw, int mb_width,
          		int mb_height, int level_idc, int max_reference_size)
          {
          	struct h264_dpb_stru *p_H264_Dpb = &hw->dpb;
          	int pic_size = mb_width * mb_height * 384;
          	int size = 0, size_vui;
          
          	switch (level_idc) {
          	case 9:
          		size = 152064;
          		break;

Your sample have mb height/widht/total: 2d/50/e10 level_idc 28 max_ref_num 3.

This is level 40 as it’s 0x28:
So size = 12582912:
12582912 / (0x2d * 0x50 * 384) = 9
