执行./rkmedia_vi_rknn_venc_rtsp_test自带的demo出现下面的错误
在/oem/usr/bin/目录下执行./rkmedia_vi_rknn_venc_rtsp_test -a /oem/etc/iqfiles/ -c /oem/usr/share/rtsp-nn.cfg -b /oem/usr/share/rknn_model/box_priors.txt -l /oem/usr/share/rknn_model/coco_labels_list.txt -p /oem/usr/share/rknn_model/ssd_inception_v2_rv1109_rv1126.rknn
会报RK_MPI_SYS_GetMediaBuffer Mode函数 this operation is not allowed!的错误
在执行命令之前也关掉默认开启的IPC应用了，其他的demo程序可以执行，只有这个demo会报错

看这个打印log信息，应该是demo代码里面VI的Chn写错了，使能和绑定写的是1，获取数据是0。把代码改一些应该就可以跑通了
