你好,我使用的设备是jetson orin nx,
在使用jetson-utils时,使用VideoOptions和VideoSource进行CSI相机的图像录制,可以达到19201080 60fps,但是当我使用这两个类进行将每一帧的图像进行逐帧保存为jpg格式的图像时,他的帧率只有4fps左右,并且我看到他仅仅在cpu上运行,并没有像录制视频一样使用到gpu,请问我应该怎么修改才能达到像视频录制一样快的帧率,下面时采集图像的主要代码:
videoSource input = videoSource::Create(“csi://0”,options1);
videoOutput* output = videoOutput::Create(“file://…/resource/image_%i.jpg”,options1);
期待您的回复,感谢。
