Multiple tests fail not able to find certainly present codecs

Overview

When packaging this package for openSUSE (version 10.0.0 from the tarball from PyPI, with ffmpeg limited to the unencumbered codecs, the full log) I get 24 tests failed including beauties like:

[  478s] ______________________ TestCodecs.test_codec_opus_decoder ______________________
[  478s] 
[  478s] self = <tests.test_codec.TestCodecs testMethod=test_codec_opus_decoder>
[  478s] 
[  478s]     def test_codec_opus_decoder(self):
[  478s] >       c = Codec("opus")
[  478s] 
[  478s] tests/test_codec.py:68: 
[  478s] _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 
[  478s] av/codec/codec.pyx:184: in av.codec.codec.Codec.__cinit__
[  478s]     ???
[  478s] _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 
[  478s] 
[  478s] >   ???
[  478s] E   av.codec.codec.UnknownCodecError: opus
[  478s] 
[  478s] av/codec/codec.pyx:193: UnknownCodecError

which doesn’t make any sense whatsoever (of course, opus is free and libopusenc is present, see the log). Any ideas, what’s going on?

Expected behavior

Tests should pass.

Actual behavior

See the log

Build report:

Again, see the log.

Investigation

I would hope that the test suite is build with isolated tests already.

Reproduction

Just run the test suite with the packages enlisted in the log (I cannot find any limitations on the versions of packages used).
