jernej: ndufresne: do you have any idea what Cedrus is expecting for slice_pic_order_cnt ? decode_params.pic_order_cnt_val matches PicOrderCntVal like I said. jernej: what I meant to say is that I don't expect HEVC to be properly specified/documented, which means there may be some fields without a clear meaning. It seems to be the case with v4l2_ctrl_hevc_slice_params.slice_pic_order_cnt. To be clear, v4l2_ctrl_hevc_decode_params.v4l2_ctrl_hevc_decode_params is properly specified and documented to be PicOrderCntVal. So the one that needs to be reviewed is v4l2_ctrl_hevc_slice_params.slice_pic_order_cnt.
