问题描述

我目前正在写使用OpenCV的,并在以下情况下实时应用:
我试图从火线800插入一个HDV摄像机拍摄的图像。
我试图对指数环上cvCaptureFromCam使用,
但没有摄像头无法找到(除了摄像头)。

I'm currently writing an real time application using OpenCV and in the following case: I'm trying to capture an image from a HDV camera plugged in firewire 800. I have tried to loop on index used on cvCaptureFromCam, but no camera can't be found (except the webcam).

还有就是我的code样品,它在指数环(逃避0的原因是网络摄像头的指标):

there is my code sample, it loop on index (escaping 0 cause it's the webcam's index) :

CvCapture* camera;
int index;
for (index = 1; index < 100; ++index) {
    camera = cvCaptureFromCAM(index);
    if (camera)
        break;
}    
if (!camera)
    abort();

在它停止对中止任何时候。

On any time it stops on the abort.

我编译在OSX 10.7和我已经测试:

I'm compiling on OSX 10.7 and I have tested :


  • OpenCV的1.2私有的框架

  • OpenCV的2.0私有的框架(这里找到:的 OpenCV2.0.dmg

  • OpenCV的由我自己编(第二版)

我知道问题是省著名商标,并有很多讨论此事,
但我不能TI找到任何解决方案。

I know that the problem is knowned and there is a lot of discussion about this, but I'm not able ti find any solution.

有谁一直在同一案件中?

Does anyone have been in the same case ?

问候。

推荐答案

首页应在启动 0 而不是 1

如果不工作,也许你的相机不支持的OpenCV。我建议你​​检查它是否在兼容性列表

If that doesn't work, maybe your camera is not supported by OpenCV. I suggest you check if it is in the compatibility list.
