FFmpeg搭配QuickSync无法实现硬件解码的问题求助

各位大佬好，我现在遇到个棘手的问题：想用Intel核显的QuickSync实现H264视频的硬件解码转H265编码，但硬件解码一直失败，报错提示：

Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scaler_0'

我用的是FFmpeg官方QuickSync教程里最基础的命令，硬件编码是正常的（这个例子里是软解码）：

ffmpeg -v verbose -hwaccel qsv -i VID_20230526_174925.mp4 -c:v hevc_qsv -b:v 5M output.mp4

但换成硬件解码的命令就不行了：

ffmpeg -v verbose -hwaccel qsv -c:v h264_qsv -i VID_20230526_174925.mp4 -f null -

看完整输出我发现，我的视频带有90度旋转的元数据，FFmpeg自动插入了transpose滤镜来处理旋转，但QuickSync硬件解码输出的是qsv格式的硬件内存表面，而软件滤镜（比如auto_scaler_0、transpose）没法直接处理这种硬件格式，导致格式转换失败。

我已经试过各种基础排查了，实在没思路了，有没有大佬能指点一下怎么解决？
