gstreamer-full: new recipe

[fnadeau]

Specify library name and version: gstreamer-full/1.24.2

gstreamer and its pluggins are maintained at a different pace.
gstreamer- 1.22.6
gst-plugings-base 1.19.2
gst-plugings-good 1.19.1
gst-plugings-ugly 1.19.1
gst-plugings-bad 1.19.1
gst-libav 1.19.1

From a maintainability point of view, any update from gstreamer upstream requires 6 PR for conan to catch-up. This does not include PR for missing items such as gst-rtsp-server. Since 1.24 it is now possible to do a full build static. This would make the version bump way easier. It should be possible to have a full build dynamic, this could be added later.

There is still a bit of work and testing todo. I would like to gather interest and comment on the package.

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
  • 2.3.0, it's close, just ahead. It actually needs 2.3.0 since it uses subprojects in meson.
• I've tried at least one configuration locally with the conan-center hook activated.
  • Hook don't works with conan 2

This won't work, unfortunately. The user-provided values for options are not available in config_options() or even configure(). You will have to del self.info.options.xyz' the options that have no effect in package_id()` instead.

[fnadeau]

I'm not sure I follow. Doc seems to do it in configure(), see second snippet where they remove fPIC.

I have no issue with moving it to package_id(), just want to understand a bit better. Thanks

[valgur]

@danimtb Maybe you or someone else from the team can clarify whether the configure() step can be used like that or not, given that you were wrestling with similar issues in the Arrow recipe. Does the standard if self.options.shared: del self.options.fPIC even work as intended?

[fnadeau]

I'm re-reading the doc and I think it should be in configure() and not in config_option() (that was a mistake as you pointed out, only settings is populated), and not in package_id(). I'll wait for confirmation on this. Thanks

[valgur]

Looks promising at a first glance. Thank you very much!

All of the sub-packages, except for gst-libav to some degree, are very likely to be used simultaneously, so packaging them as a single unit makes sense to me.

As for the difficulty of bumping 6 different packages one-by-one. That is currently quite painful indeed, but Conan devs have mentioned that support for modifying of multiple packages in a single PR will likely be added some time soon. @RubenRBS do you know if and when that feature might land on CCI?

The v2 pipeline failed. Please, review the errors and note this is required for pull requests to be merged. In case this recipe is still not ported to Conan 2.x, please, ping @conan-io/barbarians on the PR and we will help you.
