裁剪yuv文件，可以设置起始帧和最后一帧，针对所有分辨率的yuv文件，采样空间也都支持-Cut yuv file, you can set the start frame and the last one, at all resolutions of the yuv file, sample space support

RGB转换YUV，并进行灰度变换。简单的实验，非常简单。sample图片没有。-RGB transfers to YUV .

此示例演示如何有效地使用CUDA视频编码器API编码H.264视频。视频输入在YUV格式作为输入(系统CPU或GPU内存)和视频输出帧编码H.264文件-This sample demonstrates how to effectively use the CUDA Video Encoder API encode H.264 video. Video input in YUV formats are taken as input (either CPU system or GPU memor
