How to increase the buffer size of libdc1394?

不晓得换成英文标题能不能获取注意了，哈哈。
怎么增加libdc1394的缓存大小？？？？？？？？？
我在中标麒麟5上使用flycapture软件时，遇到了一个问题。
提示错误如下：
Source: IidcCameraInternal.cpp(445) Built: Nov 30 2011 14:49:25 - Error starting isochronous stream.
+-> From: Iso.cpp(1551) Built: Nov 30 2011 14:48:59 - Failed isochronous initialization. Error: 0x14.

幸好官网有解决方案：
*

In your application, manually specify the number of requested image buffers so that the maximum does not exceed 64 MB. Using the FlyCapture 2.0 API, set the numBuffers member of the FC2Config struct. Then, call the SetConfiguration member function of the Camera object.
*

Transmit images in Raw8 pixel format, and perform color processing in your application.
*

Run your application on a newer installation of Linux that uses the Juju FireWire kernel driver stack. This driver stack is compatible with libdc1394 v2, and allows buffer sizes greater than 64 MB. For more information, see https://ieee1394.wiki.kernel.org/index.php/Juju_Migration.
但是啊，前2个貌似不行，屡试不行。
第三个所给的网址也不能解决问题
所以哪位大侠若知道怎么增加1394缓冲大小，麻烦告小弟声，拜谢！
