当我ipynb使用GitHub中的RAW按钮下载文件时,它会在浏览器中显示文本(json).
我应该将此文本复制到文件中并命名xxx.ipynb吗?最好的方法是什么?
我试图IplImage使用系统库调用将对象作为参数传递给另一个程序.代码段如下所示.
#include <stdio.h>
#include <opencv/highgui.h>
#include <unistd.h>

void cb(uvc_frame_t *frame, void *ptr) {
uvc_frame_t *bgr, *bgr2, *dup;
uvc_error_t ret, ret2;
IplImage* cvImg;
IplImage* cvImg2;
IplImage* im1,im2;
dup=frame;
// printf("callback! length = %d, ptr = %ld\n", frame->data_bytes, (int) ptr);
bgr = uvc_allocate_frame(frame->width * frame->height);
bgr2 = uvc_allocate_frame(frame->width * frame->height);
if (!bgr) {
printf("unable to allocate bgr frame!");
return;
}
if (!bgr2) {
printf("unable to allocate bgr2 frame!");
return;
}

我正在运行的代码如下.
