Configure monorepo build to include plugins-rs?

General Discussion
1

I was able to manually hack and compile the plugins, but I didn’t get it’s it’s possible at all to configure meson on the monorepo so that it includes and compiles gst-plugins-rs all together with the rest.

The thing is, it’s disabled by default and AV1 is kinda impossible to do without rtpav1pay, which is in rust, even tho av1parse, is included by default…? any way we could improve the experience here?

I’ve tried many things, but always got with an empty gst-plugins-rs folder in my build folder and this python error I coult not get over, even after manually copying the source in there.

Things I’ve tried:

  • when doing meson setup builddir/ -Drs=enabled
[...]

Subproject gtk : skipped: feature gtk disabled

Executing subproject gst-plugins-rs

subprojects/gst-plugins-rs/meson.build:1:0: ERROR: Unhandled python exception

    This is a Meson bug and should be reported!

tried also meson configure build.old/ -Drs=enabled, but no difference…

I have cargo & cargo-c installed, not sure what I am missing…

Thank you!

Just to be sure, you can also build gst-plugins-rs (or just the rtp plugin there) separately using cargo once you have built the other monorepo modules. Either inside the uninstalled dev environment, or against the installed libraries (with PKG_CONFIG_PATH etc set).

Not an answer to your question, but I think there’s not enough info there anyway (what branch/commit are you building? what’s the full meson configure log etc.)

Thanks for your reply. Yes, I managed to build them separately as mentioned before, but I was wondering how is it supposed to work with the monorepo build and configure steps, for example to compile just the video plugins in rust, not all?

I’m using just the git main branch from yesterday (version 1.25.1.1) and the commands that i’ve posted above.
