Revision history [back]

Lately i observed this issue is always with all other camera packages also. The problem is, when i set in launch file for any node then it is not working. When i run individually it works.

For e.g. When i set usb_cam node in launch file with some custom parameter then process dies and if i don't use launch file and try to roslaunch usb_cam from command line it works.

Is there anything which needs more attention?
