Made it!

nm -D electron | awk '/ \w (av|ff)/{print $3}' | xargs rebind -w -i electron

With that patch to rebind:

So crazy but works.

Is this workaround still necessary?

It's fixed in latest versions of Electron (restored explicit dependency on libffmpeg).
I like the previous behavior a bit more though, because you don't have to depend on shared ffmpeg libraries with specific version (major number) on target user system.

(Actually it's possible to remove libffmpeg dependency even in latest versions, but it's even more crazy, you need to patch binary for that.)
