No underwater video and ROV can not move by joystick in GAZEBO

[Shepherd-Gregory]

Hi~
I'm using this package to run open-source SLAM algorithms but I haven't got any underwater video except mosaics on the /image_raw window, the ROV can not move by joystick in GAZEBO either, and after I click the "play" button on GAZEBO GUI, the ROV disappears soon ...

My system env:

~ Ubuntu 16.04 64bit + ROS-Kinetic
~ 16G RAM+i5 4210U+ integrated graphics chip + xbox360 joystick (test ok)

My cmd lines:

1. run bluerov node:
   $ roslaunch bluerov_ros_playground bluerov2_node.launch bluerov_node_device:=udp:localhost:14550
2. Visualize video stream:
   $ roslaunch bluerov_ros_playground video.launch
   3.Run SITL and start gazebo.launch:
   $ cd ardupilot/ArsuSub
$ sim_vehicle.py
$ gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480 ! videoconvert ! x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5600
$ roslaunch bluerov_ros_playground gazebo_teleop.launch

The README.md confuses me and I would be appreciated if you can help.

Hi Shepherd, sorry for not updating this repository and helping others. This repository was an initial step to create a good BlueROV2 ROS package. But since ROS, Ardupilot and Gazebo changes and breaks so much, it's not possible for me to track all necessary changes in this repository.

Right now it's not possible for me to debug and help your problem, but I can give small hints.

The video will only work if you are connecting with the real ROV, it does not work with the simulation, and it should work without problems.

The Ardupilot simulation, should work if you use the correct version of each package, but right now this is a bit hard, you'll probably need to update something in the code and debug to check what is going on.

Hey, bro~ Thanks for your previous work and prompt reply. I'll try to conduct the simulation with Ardupilot, and finally run my pkg on a real ROV. Anyway, thanks again~
