[ros-users] image_rotate can't find compressed image format

[Blaise Gassend]

Have you tried setting compressed_image_transport_jpeg_quality
somewhere in the tree above the image topic (in the root for example)?

That should get rid of the error, but no idea if it will fix the lag problem.

This should probably be ticketed against image_pipeline.
