FFMPEG 可以将 EXR 转换为 TIFF，也可以将 TIFF 转换为 JPG，但不能将 EXR 转换为 JPG

我尝试批量转换扩展图片JPG图像。转换扩展到JPG 不起作用，当我尝试打开文件时出现损坏错误。

ffmpeg.exe -y -i C:/test.exr C:/outs.jpg

但转换EXR 转 TIFF 功能美好的

ffmpeg.exe -y -i C:/test.exr C:/outs.tiff

并转换TIFF 转 JPG 功能以及：

ffmpeg.exe -y -i C:/test.tiff C:/outs.jpg

我不想双重转换文件来获得最终结果..有解决这个问题的方法吗？

第一个命令的输出：
