Problems using Tracktion engine within a plugin

Tracktion Engine

That definitely improves things!

Now I no longer see the triggerAndWaitForCallbak() related errors, although after engine initializes there are errors as well, seemingly related to device manager? This is the stack trace without setting a brakpoint (the first assertion failure raised is for tracktion_DeviceManager.cpp:154):

Looks like more message thread assertions. How about this:

    void prepareToPlay (double sampleRate, int expectedBlockSize) override
    {
        if (teMembers.get() == nullptr)
        {
            auto initialiseEngine = [this]
            {
                teMembers = std::make_unique<TracktionEngineMembers>();

                // These 3 functions below used to be in the EngineInPlugin constructor
                teMembers->audioInterface.initialise({});
                setupInputs();
                create4OSCPlugin();
            };

            // Do this async to ensure it happens on the message thread
            if (MessageManager::getInstance()->isThisTheMessageThread())
            {
                initialiseEngine();
            }
            else
            {
                jassert (! MessageManager::getInstance()->currentThreadHasLockedMessageManager());
                WaitableEvent finishedSignal;
                MessageManager::callAsync ([&]
                                           {
                                               initialiseEngine();
                                               finishedSignal.signal();
                                           });
                finishedSignal.wait (-1);
            }
        }

        auto prepareEngine = [this, sampleRate, expectedBlockSize]
        {
            setLatencySamples (expectedBlockSize);
            teMembers->audioInterface.prepareToPlay (sampleRate, expectedBlockSize);
        };

        // Do this async to ensure it happens on the message thread
        if (MessageManager::getInstance()->isThisTheMessageThread())
        {
            prepareEngine();
        }
        else
        {
            jassert (! MessageManager::getInstance()->currentThreadHasLockedMessageManager());
            WaitableEvent finishedSignal;
            MessageManager::callAsync ([&]
                                       {
                                           prepareEngine();
                                           finishedSignal.signal();
                                       });
            finishedSignal.wait (-1);
        }
    }

hi, more improvements! Now I don’t seem to see any more message thread assertions. The app still quits after initialization and I see a number of detected leaked objects (I guess this is because the app does not quit gently). The output is below.

Maybe now this is related to my specific setup, so I should try loading the plugin with other hosts as well.

Can you run this under gdb? It looks like the app is quitting in a weird way before it gets to load the Edit.

I think the assertions are because the whole plugin is being leaked: *** Leaked objects detected: 1 instance(s) of class EngineInPluginDemo

Yes, it would be good to see if this happens in other hosts too. (Like the juce Audio Plugin Host).

This the output in gdb, does not seem to tell much :S

I can’t try with other hosts right now but I’ll try to do it next week see if I get some luck. Thanks!

Ok, I’ve cleaned up the EnginePluginDemo now so that it should work correctly on Linux: https://github.com/Tracktion/tracktion_engine/commit/ffb2690c4d012a3ac325039110574084af1b29e2

I’ve tested this on Ubuntu 16.04 with the JUCE Audio Plugin Host.
I’ve also fixed the PIP so that it should build as a synth now with MIDI input without modification.

If this still isn’t working in the Elk host let me know as there might be something more subtle going on.

47

That’s great, thanks a lot @dave96!
I don’t have a Pi available for testing now (that’s also why I have been silent about the issue since some weeks), but hopefully I’ll be able to test it soon. I’ll also tell ELK guys and see if they can test it themselves so we have an answer to this. @stez-mind

Thanks a lot!

Hi again,
This is just to say I have not yet been able to test again on the ELK hardware, but I could test the engine in plugin demo and my own work-in-progress app (refactored to instantiate the engine like in the engine in plugin demo) in an Ubuntu Virtual Machine (with audio working) and it works fine both using AudioUnitPluginHost and ELK’s sushi host. Hurray!

Once I can finally get my Pi again to run some tests on actual ELK hardware I’ll report. I hope it is going to work just fine although to optimize it for the dual-kernel ELK thing there are some details I’ll have to look like ELK requiring a patched JUCE (not sure if this is still needed). Anyway, I’ll report here once I get some tests done, but this might not be until a month or two from now. Meanwhile I’ll start another thread with some doubts I have about how to structure my app, adding content to te engine value tree, etc.

Thanks everyone, specially to @dave96, for all the answers and time spent on this.

Hi everyone again,

I was finally able to get my rpi running with the ELK hardware and OS, and test @dave96’s changes in the tracktion engine and… it works! I was able to compile the EngineInPluginDemo project from tracktion engine (381e3220571419d726be759f305576bba2df46cc), using ELK’s modified JUCE (which is currently needed for running JUCE apps in ELK). I did some modifications to the EngineInPluginDemo to also play some background file in addition to the synth. I all works fine, including MIDI input. Awesome!!!

I think there are still some optimizations to do for ELK on the JUCE side, because ELK uses a dual-kernel strategy (much like in Bela), and tracktion needs to get some system timer information (using JUCE’s int64 Time::getHighResolutionTicks() method) which in the ELK context becomes non real-time safe. To fix this the method needs to be patched to use a timer function provided by ELK instead of the syscall (much like it is done for bela). If this is not done in this way, then the performance decreases and audio drops might happen because there are many mode switches. It should not be a hard fix and in any case it is not tracktion engine related. I’ll report in this post if I manage to fix that.

Thanks to everyone and specially to @dave96!
