以上代码运行前需要先下载：ffmpeg工具包

下载路径：https://www.gyan.dev/ffmpeg/builds/

需要放在D盘：D:\ffmpeg-9.0.2-full_build\bin注意不要嵌套多层文件夹，bin 直接在 ffmpeg 根目录下面..

CMD直接测试：

用ffmpeg 将 mp4转化成yuv

源视频路径："C:/Users/andin/Desktop/源视频.mp4"

导出yuv路径："C:/Users/andin/Desktop/test1.yuv"

对应命令：

"D:\ffmpeg-9.0.2-full_build\bin\ffmpeg.exe" -y -i "C:/Users/andin/Desktop/源视频.mp4" -pix_fmt yuv420p -colorspace bt709 -color_primaries bt709 -color_trc bt709 -color_range pc -c:v rawvideo -r 30000/1001 "C:/Users/andin/Desktop/test1.yuv"

用ffmpeg 将 yuv转化成mp4

选中的yuv路径："C:/Users/andin/Desktop/test1.yuv"

输出的mp4路径："C:/Users/andin/Desktop/test2.mp4"

对应命令：

"D:\ffmpeg-9.0.2-full_build\bin\ffmpeg.exe" -y -f rawvideo -video_size 1280x720 -pix_fmt yuv420p -color_range pc -r 30000/1001 -i "C:/Users/andin/Desktop/test1.yuv" "C:/Users/andin/Desktop/test2.mp4"
