I get an error when republishing the image I shot with ros2 run ffmpeg

Question

I get the following errors when republishing the image I took with ros2 run ffmpeg.;

ros2 run image_transport republish ffmpeg in/ffmpeg:=image_raw/ffmpeg raw out:=image_raw/uncompressed --ros-args -p "ffmpeg_image_transport.map.hevc_rkmpp:=hevc"`



terminate called after throwing an instance of 'image_transport::TransportLoadException'
  what():  Unable to load plugin for transport 'image_transport/ffmpeg_sub', error string:
According to the loaded plugin descriptions the class image_transport/ffmpeg_sub with base class type image_transport::SubscriberPlugin does not exist. Declared types are  image_transport/compressedDepth_sub image_transport/compressed_sub image_transport/raw_sub image_transport/theora_sub

I don't want to replace the parameters specified in the errors. I want to do this with ffmpeg. how can i fix this

After running ros2, I want to list the topics, echo them and view them with rviz2 and image uncompressed.Afterwards, I want to use and show this uncompressed image in my Python detection project.
