Looking for a sanity check on my understanding.  I've written a test case (see 
below) that passes.  What puzzles me is that the call to mediaStatus() returns 
"LoadedMedia" after a call to unload().  Is that correct?


    void status()
    {
        AVDemuxer demux;
        QCOMPARE(demux.mediaStatus(), MediaStatus::NoMedia);
        QCOMPARE(demux.atEnd(), false);
        QCOMPARE(demux.fileName(), QLatin1String(""));
        QCOMPARE(demux.isLoaded(), false);
        
        QVERIFY(demux.setMedia(testFile1()));
        QCOMPARE(demux.mediaStatus(), MediaStatus::NoMedia);
        QCOMPARE(demux.atEnd(), false);
        QCOMPARE(demux.fileName(), testFile1());
        QCOMPARE(demux.isLoaded(), false);

        QVERIFY(demux.load());
        QCOMPARE(demux.mediaStatus(), MediaStatus::LoadedMedia);
        QCOMPARE(demux.atEnd(), false);
        QCOMPARE(demux.fileName(), testFile1());
        QCOMPARE(demux.isLoaded(), true);

        QVERIFY(demux.unload());
        QCOMPARE(demux.mediaStatus(), MediaStatus::LoadedMedia);  // ??? why 
status shows loaded?
        QCOMPARE(demux.atEnd(), false);
        QCOMPARE(demux.fileName(), testFile1());
        QCOMPARE(demux.isLoaded(), false);
    }
