我正在尝试开发一种利用 nvidia 硬件加速功能的转码服务（此过程中使用的 gpu 是 Tesla T4）；我想为我的视频生成一个 mpeg-dash 播放列表，以便我可以流式传输它；
ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -i mobil1.mp4 -c:v h264_nvenc -c:a aac \
-map v:0 -b:v:0 4000k -maxrate:0 5500k -bufsize:0 4500k -filter:v:0 "scale_npp=1920:1080:force_original_aspect_ratio=decrease" -map 0:a -b:a 128k \
-f dash dash.mpd
但是当上传移动视频（具有旋转元数据）时，我遇到以下错误：
Impossible to convert between the formats supported by the filter 'transpose' and the filter 'auto_scaler_0'
Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while processing the decoded data for stream #0:0
我该如何解决这个问题？我正在使用以下docker镜像： jrottenberg/ffmpeg:4.4-nvidia
