opencv读取MP4视频文件报错 Inappropriate ioctl for device

照着horizon_runtime_sample自己写了yolov5 Demo测试上板推理速度读取视频时报错

执行脚本

bin=../aarch64/bin/run_yolov5_672

lib=../aarch64/lib

export LD_LIBRARY_PATH=${lib}:${LD_LIBRARY_PATH}

export BMEM_CACHEABLE=true

${bin} \

--model_file=../../model/yolov5_672x672_nv12.bin \

--image_file=../../data/det_images/2.mp4 \

--config_file=./config.json \

--image_height=672 \

--image_width=672 \

--top_k=5 \

--videoFlag=true

报错代码
cv::VideoCapture capture;
VLOG(EXAMPLE_DEBUG) << FLAGS_image_file;
capture.open(FLAGS_image_file);
int index = 0;
if (!capture.isOpened())
{
VLOG(EXAMPLE_DEBUG) << "文件打开失败";
return -1;
}
