FFmpeg 5.1 and 5.0 are two major versions and never ever are guaranteed to be compatible backwardly.
Your tools show that we only added symbols, therefore a program built with 5.0 will run with 5.1 at runtime, which is what .so numbering is about.
We’re not glibc and will never be, because we’re not a libc, nor an OS SDK.
If you build against 5.1, use 5.1 at runtime.
But if you built with 5.0, then 5.1 will run, as expected.
