Thanks to Colin Weinshenker for his work on multiple camera driver.
Update current status: Our multiple camera driver will dramatically drop frames when record a rosbag. So the solution is we save multiple cameras frames to h264 files and only publish timestamp and frame_id to ROS for post processing. This repo is no longer maintained and will leave it at a base work for anyone working on PX2.
