Package request: ros-jazzy-web-video-server, ros-jazzy-async-web-server-cpp

[jfrancis71]

Package name

ros-jazzy-web-video-server, ros-jazzy-async-web-server-cpp

Operating System(s)

• linux-64
• linux-aarch64
• osx-64
• osx-arm64
• win-64

Additional context (optional)

I would like to use the web video server to support streaming images from my robot to my browser based application.

I believe ros-jazzy-async-web-server-cpp is a dependency of the web video server.

Previously I was unable to build these two packages from the repository in a RoboStack Jazzy environment.

However, both of these packages have received PR's which means I can now build these from the GitHub repo's:
https://github.com/fkie/async_web_server_cpp: branch ros-develop
https://github.com/RobotWebTools/web_video_server: branch ros2

These are the PR's which fixed the build (they are now merged into above mentioned branches):
fkie/async_web_server_cpp#7
RobotWebTools/web_video_server#190

Tested on Ubuntu 22.04.5 LTS, RoboStack Jazzy on a Dell Intel machine and also on Raspberry Pi 3B+ Ubuntu 22.04.5 LTS, RoboStack Jazzy.

Do you want to open a pull request? You can include the PRs as patches if they haven’t been released yet.

I am sorry I don't really know how to do a PR for this.

@jfrancis71 What do I need to do to include web_video_server to RoboStack distribution? Should I just release the new version to rosdistro?

However I wasn't quite sure what it meant. Is the answer yes?....

To be clear on what I think I do understand, the PR's to make this work with RoboStack have been merged into the relevant branches (on the relevant original GitHub repo's).

Apologies for not being more precise, my knowledge of the release process and conda builds is a bit vague. Any help would be much appreciated.

I notice that in https://github.com/RobotWebTools/web_video_server

they have a new commit bumping version from 2.1.0 to 2.1.1 in package.xml

rosdistro_snapshot.yaml in Robostack Jazzy has the following entry:
web_video_server:
tag: release/jazzy/web_video_server/2.1.0-1
url: https://github.com/ros2-gbp/web_video_server-release.git
version: 2.1.0

There are some docs in https://robostack.github.io/Contributing.html, if you are confused after reading this feel free to ask more questions.

Can I just add it to vinca.yaml under tag packages_select_by_deps: (specifically under the conditional Linux tag)?

running vinca --multiple --platform linux-64 has built a recipe file in ./recipes/ros-jazzy-web-video-server/recipe.yaml

I am unsure how to test it.

Also I note, in rosdistro_snapshot.yaml; it is referring to the older versions for web_video_server and async_web_server_cpp; do these need to be updated?

Question: Does it actually need to be added to vinca.yaml, or is it the case that there is already an attempt to build it, but it is not available as a conda package because it failed to build (using previous package version)?

Thank you

I am unsure how to test it.

You can just add it to vinca, and run pixi run build. This will generate the recipe and try building it.

Also I note, in rosdistro_snapshot.yaml; it is referring to the older versions for web_video_server and async_web_server_cpp; do these need to be updated?

In theory, the rosdistro_snapshot.yaml should only be changed on sync/full rebuilds, to avoid possible ABI incompatibilities due to changes in packages. However, if @Tobias-Fischer is ok with it, just for this time we could even just bump the versions of web_video_server and async_web_server_cpp (only because they were never built before) to avoid the need to apply the patches.

Question: Does it actually need to be added to vinca.yaml, or is it the case that there is already an attempt to build it, but it is not available as a conda package because it failed to build (using previous package version)?

It need to be added to vinca.yaml. All the packages in the vinca.yaml are the one that we build, while packages that are not in https://robostack.github.io/jazzy.html are not in the vinca.yaml (or are not dependencies of packages that are in vinca.yaml.

Works for me :)

[jfrancis71]

Thanks, I think I am making progress.

I run pix run build
The web server package I think does not get built.

I add web_video_server to vinca.yaml under tag: packages_select_by_deps
It fails with build errors (as I experienced in my original conda attempt to build).

In rosdistro_snapshot.yaml I bump the versions of web_video_server and async_web_server_cpp to the newly released versions. It seems to work.

Question: I am doing this on a Dell Intel computer running Ubuntu 22.04.05. Is this build process just building for Linux on Intel or is it targeting other platforms as well? Do I need to check for other platforms?

I have access to Linux ARM and Intel MacOSX. I do not have a windows or MacOSX ARM.

I have access to Linux ARM and Intel MacOSX. I do not have a windows or MacOSX ARM.

The CI in the PR will handle that, feel free to open it, and we can check if there is any unexpected failure.

I have installed and tested web-video-server using RoboStack Jazzy (mamba install) on both a Dell Intel, and Raspberry Pi 3B+ (all Ubuntu 22.04.5)

I am pleased to say it works on both platforms.

Thank you all for your help.
