description:
Tests: adjusted mp4 tests to use mpeg4 encoder.

It turns out libopenh264 encoder as provided on Fedora is not stable,
and, in particular, mp4 tests fail due to this on current Fedora Rawhide.
As a workaround, switched to using mpeg4 internal encoder instead,
which is always available.
