Start multiple camera nodes from single roslaunch XML about realsense-ros HOT 5 CLOSED

Official support for Multiple cameras is being release soon.
Launching multiple camera from a single launch file wasn't in our original acceptable criteria, but we've capture this and it will get addressed -- may not be in the first release.

@mdhorn Do you have a timeline for this release?

from realsense-ros.

We don't have a hard date for this fix. It is high on the list, but there are a couple of other items that are in front of it.

The issue stems from librealsense assuming all cameras would be started from the same process/thread whereas our ROS module launches each as a separate process via a nodelet.

@nmertins @prarobo This required some changes at the librealsense level, which has been implemented in their latest "master" branch IntelRealSense/librealsense@bff3ab5

We are waiting for librealsense to make a "release", to update our ROS repo with the related launch file changes. In the mean time, you could do the following:

• Download the latest librealsense "master" branch as mentioned above.
• Copy the file "realsense_r200_multiple_cameras.launch.xml" in the attachment into the "launch/includes" folder.
• Copy the file "realsense_r200_multiple_cameras.launch" in the attachment into the "launch" folder. Make sure to read the comments in the file and make the changes accordingly. Then launch the file.

Thank you for your patience and please let us know if this works.

Fixed in Release 1.1.0
