我分别在RTX 4090和Jetson TX2 NX的虚拟环境中使用pip install pynvjpeg安装了pynvjpeg。
在RTX 4090和Jetson TX2 NX中，我分别使用OpenCV中的imencode和pynvjpeg中的encode方法对分辨率4K的图片进行编码时间测试。

在RTX 4090中，使用OpenCV的编码方式，编码时间70ms；使用pynvjpeg的编码方式，编码时间10ms
在Jetson中，使用OpenCV的编码方式，编码时间110ms；使用pynvjpeg的编码方式，编码时间150ms
为什么在Jetson中，使用pynvjpeg的编码方式，编码时间会更长？
