🐛 xaibo init fails when installing livekit dependencies (av build error)

[MFA-X-AI]

It appears that the current livekit module is broken in both local and the github runner.

Here's the logs from my dev server:

      Warning! You are installing from source.
      It is EXPECTED that it will fail. You are REQUIRED to use ffmpeg 7.
      You MUST have Cython, pkg-config, and a C compiler.

      pkg-config could not find libraries ['avformat', 'avcodec', 'avdevice', 'avutil', 'avfilter', 'swscale', 'swresample']

      [stderr]
      Package libavdevice was not found in the pkg-config search path.
      Perhaps you should add the directory containing `libavdevice.pc'
      to the PKG_CONFIG_PATH environment variable
      Package 'libavdevice', required by 'virtual:world', not found
      Package 'libavfilter', required by 'virtual:world', not found

      hint: This usually indicates a problem with the package or the build environment.
  help: If you want to add the package regardless of the failed resolution, provide the `--frozen` flag to skip locking and
        syncing.

This looks like it tries to compile av because it can not use the wheel and is missing dependencies to compile it.

Unfortunately, there is probably very little we can do about it.

For your particular issue, it already tells you that it expects to use ffmpeg 7 but you only have ffmpeg 6 available. You can try getting it from a PPA, but note you will not only need the binary, but also the dev headers so av can build against those.
