Hi everyone, I’m currently working on a project that requires the video feed from a drone in Gazebo. I’m launching the simulation using the command make px4_sitl gz_x500_vision, which runs without issues. In QGC, I’ve set the video settings to UDP h.264 on port 5600, but I’m not seeing any video fe…

I believe I have this same issue. When running in classic were you using a camera plugin? I haven’t found where there is an ability to stream video on UDP in gazebo that is not gazebo-classic. Just seems odd that isn’t a solved problem, so I feel like I’m missing something.

Hi Mark, I’m pretty sure this just isn’t implemented yet into the simulation on Gazebo Harmonic as the Gstreamer plugins haven’t been made yet that take the /camera topic from gazebo and put it out as a video stream on UDP 5600. I noticed this when digging through the model files for the H480 (I th…

Wow thank you for the reply. I would love to know how you’re able to get video from the camera. Long story short I am hoping to get video back through px4 for a camera that I plan to have on a companion rPi, so I am trying to simulate that from gazebo to qGC and to PX4 so that I can test. I reall…

Hi Mark, No worries, this is the only solution I was able to configure to pull the video feed from Gazebo but sadly it still doesn’t show in QGC. If that was needed I don’t see why you couldn’t write your own ROS2 node that uses gstreamer to put the video feed established out on the correct port fo…

[image] archiehocknell: ros_gz_bridge First, thank you so much for this info. I’m not sure if my setup is broken or not but figured I’d ask to see if you’ve ever seen this. I am able to see the camera in gazebo. I can run gz topic -l and see the camera topic. In fact when I run “gz topic …

Hi Mark, I have seen this before but I cant remember where. Let me have a think but this may help. I think my instructions were wrong on terminal 2. I don’t think it’s necessary to source ./install/setup.bash so step 3 can be omitted. Let me know how you get on.

Unfortunately no. I could see the gz topic getting messages, but I could never get those messages to bridge to ros2. I essentially switched to using px4 with Unreal instead of Gazebo for now.

I cant think of what else to try Gazebo. i’ll give Unreal a try, thanks, appreciate the quick reply!

You need to use the bridge ros2 run ros_gz_bridge parameter_bridge /camera@sensor_msgs/msg/Image@gz.msgs.Image where /camera is the full topic name ros_gz_bridge/README.md 96f92fc71 # Bridge communication between ROS and Gazebo This package provides a network bridge which ena…

Hey @markj9 were you able to find a solution? I’m getting the exact same error, I feel like I’m so close just missing something obvious.
