Compressed image transport support

[roboticlemon]

Hi All,

Currently this driver doesn't appear to support compressed_image_transport which means recording the image topic will use an absurd amount of disk space. This also affects streaming for viewing purposes (like over a wireless connection).

Are there any plans to implement such support or does anyone know of any forks that do?

Cheers

I'm not sure if this helps but you can republish the stream (compressed_image_transport, Section 4) and get the compressed stream that way

rosrun image_transport republish raw in:=camera/image_raw out:=camera/image_repub

It is a bit of a hack solution but is what I've been using.

do you mean doing sth like this?
rosrun image_transport republish raw in:=/camera/color/image_raw/compressed out:=camera/image_repub image_transport:=compressed
if so the realsense complains about the encoding needed by the subscriber:
[ERROR] [1650095024.946461092]: Client [/image_republisher_1650095024664204994] wants topic /camera/color/image_raw/compressed to have datatype/md5sum [sensor_msgs/Image/060021388200f6f0f447d0fcd9c64743], but our version has [sensor_msgs/CompressedImage/8f7a12909da2c9d3332d540a0977563f]. Dropping connection.
could you help me out?
