I hope to find something like. I don't believe you can from here :. Based on the code, you seem to be right.

Is there a good reason to connect this statically to video0? Or are other packages avilable with a more flexible interface?

In order to ease the manual installation process, we provide the necessary Chocolatey packages. Please download these packages from this GitHub repository. Once these packages are downloaded, open an administrative shell and execute the following command:. Download the latest package for Windows, e. Note Ardent and earlier : There seems to be an issue where extracting the zip file with 7zip causes RViz to crash on startup.

Extract the zip file using the Windows explorer to prevent this. Start another command shell and run a Python listener :. See the tutorials and demos for other things to try.

So I'd like to check how to upstream it with you before the final PRs:. Personally, I think it would be best if you made a PR to this fork, and then we eventually merge it in here. As this repository is used only for a set of demos and is not tested on all our platforms or actively maintained, I would recommend starting with option As far as maintenance goes, I don't think any of us in the ros2 team has the bandwidth to take on additional packages.

I got confirmation from vrabaud that he is willing to host the ported packages on a ros2 branch of the upstream repository and to give you write access to maintain the ros2 branch of that repository. A ros2 branch has been created. Next we'll fix the root cause there with after your issue moved there or you can contribute if you like. I'd like close this thread, because I think it has already been achieved, and thanks for all your great support! Skip to content.

Nice work! Regardless of the maintainers' stand on the existence or maintenance of a ros2 branch, changes that are backward compatible if any should be submitted on the latest ROS 1 branch to minimize the diff between the ROS 1 and ROS 2 version.

Is the only aim of ROS 2 to change to distribution protocol? ROS 2 will allow you to use the ROS2 concepts and communication protocol but will not change the internal code of these libraries. ROS 2 has several goals and one of them is changing the distribution protocol. To find more information about the various goals of ROS 2 and changes from ROS1 I encourage you to look at the design documents available on design.

It really helps, I think I will use only ROS 1 with the nodelets functionnalities in order to be as close as possible of real time. Skip to content.

Wiki Tutorials.I had a question regarding the installation of OpenCV. Is there a particular reason why OpenCV is precompiled instead of using the OpenCV versions available in chocolate repository? My memory is hazy, and I don't have a Windows machine to verify handy at the moment. But I believe the binary releases from upstream and chocolatey were compiled for Python 2 rather than Python 3, which is needed for ROS 2.

From the OpenCV chocolatey package description :. This package installs precompiled OpenCV binaries. This does not allow you to customize the features compiled into your installation. This download is about MB. If you wish to customize the features compiled in your installation, then you must compile OpenCV yourself.

I didn't see anything in the description of the chocolatey package which hints at the target python interpreter for current releases.

If they've switched to Python 3, we may be able to deprecate our custom binary distribution in favor of the chocolatey package.

At the time we weren't able to use the Chocolatey packages, not sure if they were non-existent or not built with VS Another motivation for building a custom version was also to have for internal testing and to ship to users the debug libraries. As it looks like the Chocolatey packages came a long way in the last couple years, it may be worth reconsidering the chocolatey packages and checking if they're built with Python 3 bindings for future-proofness.

Though the debug libraries will likely not be included so users building in Debug would need to either build their own or ROS 2 releases could keep shipping a custom built archive. Oh thank you for expanding on the reason for the prebuilt binaries. I appreciate that. For now I will just use the OpenCV provided.
