I did an SVN update (to revision 948), rosmake'd, and then applied rosparam and queue changes. Still no success. Did confirm that the parameter was getting set (rosparam get) Did also notice that varying the parameter changed the sample rate (kind of like framerate did) Haven't seen any impact of the queue in the pipeline. I tried this for the video posted above. I generally use launch files, but I've also tried the same commands at the command prompt with no difference in result. Did I miss a step? Is anyone else having success? -- View this message in context: http://ros-users.122217.n3.nabble.com/gscam-and-stored-video-tp1598009p1642605.html Sent from the ROS-Users mailing list archive at Nabble.com.
