LiveCompositor Examples Failure - libavutil.so not loading

Hey,

I’m trying to experiment with LiveCompositor but my attempt to run the examples fails:

.../_build/dev/lib/membrane_live_compositor_plugin/priv/v0.3.0/linux_x86_64/live_compositor/live_compositor: error while loading shared libraries: libavutil.so.58: cannot open shared object file: No such file or directory

I’m curious what might be wrong and how to fix it.

Thanks

That shared library is part of ffmpeg, do you have ffmpeg installed on your system?

Yeah, it is

What OS are you using?

Hi, live_compositor is built against a specific version of FFmpeg. We plan to remove that limitation in the future, but for now, you have to install a particular version. In this case, it is FFmpeg 6.

I’m using Ubuntu 22.04

It appears my OS is not compatible with FFmpeg 6

I’ll upgrade the OS and try again

Upgrading Ubuntu to 24.04 fixes this. FFmpeg 6 works on it

Thanks for all the input
