show current played song / Playlist in Textfile or via Telnet

I've pretty much nailed down this bug. It happens when a Hotcue is activated (the track was previously paused) and then you hit the play button. Judging from the code this might have been done more as a *feature* than it being an actual bug. For reference, this is the actual offending code, from src/engine/cuecontrol.cpp[649]:

void CueControl::cuePlay(double v) {
    QMutexLocker lock(&m_mutex);

    if (m_bPreviewing && !v) {
    // we're previewing? Then stop previewing and go into normal play mode.
        m_pPlayButton->set(1.0);
        m_bPreviewing = false;
    }

    if (m_bPreviewingHotcue && !v) {
        m_pPlayButton->set(1.0);
        m_bHotcueCancel = true;
    }

    lock.unlock();
}

Where it checks for m_bPreviewingHotcue is where it gets hung up.

Looking through the logs apparently this was a *feature*. This fixes the long standing issue of getting the track to resume when previewing using cue and then pressing the play button.

Great... Those comments were meant for another bug. As for this feature, you can use the CUE file recording feature in the new 1.10 version of Mixxx. If you have it record a CUE file along with the sound recording it will spit out the playlist into the CUE file. The output gets flushed after every song is logged so it can be used on the run.

Mixxx now uses GitHub for bug tracking. This bug has been migrated to:
