ioctl(fd, VIDIOC_QBUF 返回 -1 通常表示在将缓冲区入队列时发生了错误。这可能是由于以下原因之一导致的： 1. 您传递的参数有误。请确保您提供的是正确的缓冲区指针和索引。 2. 您的摄像头可能已经关闭或发生了其他错误，导致无法对其进行缓冲区操作。 3. 系统资源不足，例如内存不足、文件描述符不足等。您可以检查错误代码以获取更多信息。如果错误代码是 EINVAL，则表示您传递的参数有误。如果错误代码是 EIO，则表示输入/输出错误，这可能是由于以下原因之一导致的：设备已经关闭、设备已经被卸载、设备损坏等。您可以查看系统日志以获取更多详细信息，以便更好地诊断问题。同时，您可以尝试重新打开设备并重试操作，也可以尝试释放一些系统资源以腾出更多空间。
