Empty UI after building from source code in VST2 and VST3 crash

Hi!

After assembly on Mac OS X 12.1 (with M1), the x64 VST2 plugin works in the Ableton Live 11, but it has an empty interface window (just white). x64 VST3 plugin crash the Ableton Live 11, crash log lines:

dpf_factory::create_instance => 0x16c461518 {dpf_tuid_class} {v3_component} 0x30f6aca88
dpf_component::unref                   => 0x6000037ec510 | refcount is zero, deleting everything now!

My build log:

What can I fix?

ps I am very inspired by the ability to develop VSTs with JS UI, hopefully, in the future, this will become generally accepted! :)

Hi, thanks for the report. This plugin depends on this library which is actually a wrapper around DPF that adds plugin-environment-friendly web views and JS bridge for a subset of the DPF API. The underlying native plugin formats support (including VST3) comes from DPF and last time I checked VST3 was work in progress, don't expect it to work yet.

I would start by testing if any of DPF's own VST3 examples work for you. If they do work then it is worth revisiting the web wrapper (haven't touched it for a while). If not, please file an issue on DPF's GitHub based on one of its examples.

Also regarding the VST2 it is probably related to M1... unfortunately I don't have access to such kind of computer.

Got it about VST3... but I want VST2 anyway. I build it for x86, not ARM, there shouldn't be any difference between M1 and Intel CPU. Most of my old VSTs work great on M1.
I tried to build hiphop and its examples, there's UI only in d_astone, d_jitdrum and d_webgain works with white windows. All VST3 plugins crash the same way. Ok, how can I debug it or make something useful to solve this (UI work)?

The UI in 1.0.1 release you built doesn't work either - just a white window.

I see. d_astone implements a native view using DPF's graphics library, d_jitdrum, d_webgain and castello implement a web view. So if the later three are failing it is definitely the web view part and not DPF...

It has to be some M1+Rosetta thing. Mac specific code can be found here

I would add some debug messages especially in CocoaWebView.mm , then a host can be started from the command line to read such messages for example /Applications/REAPER.app/Contents/MacOS/REAPER . Assuming the plugin DSP works and there are no crashes, I'd start by checking if the AppKit / WebKit stuff is initializing as expected. The web view is initialized in CocoaWebView::CocoaWebView(). I'd love to do this on my own but the issue is just not reproducible on x86. Ping me if you need further debugging tips.

Another interesting test is to add console.log() calls in the plugin's JS code, they are redirected to stdout. That will tell us if the WKWebView is running at all or not...

What happens when running the plugin in a x86 host? so everything goes through Rosetta (both host and plugin).

What happens when running the plugin in a x86 host? so everything goes through Rosetta (both host and plugin).

This's how I do this. You can't use ARM plugins with an x86 host.

Will try to debug it tomorrow.

Well, I found a bug: the white screen appears when your custom VST2 path contains spaces - we need to escape them, the webview can't find the html

But after this it has random crashes: 30% VST2 can start the first time and works fine (or crash), 100% it will crash DAW if it will be added to a track the second time. The same way the rest hiphop examples plugins work (except d_astone, it works stable before and after the patch).

Crash traces looks like:

Well, I found a bug: the white screen appears when your custom VST2 path contains spaces - we need to escape them, the webview can't find the html

Oh wow cannot believe that was it, thanks! my local paths do not contain spaces so that makes total sense.

But after this it has random crashes: 30% VST2 can start the first time and works fine (or crash), 100% it will crash DAW if it will be added to a track the second time. The same way the rest hiphop examples plugins work (except d_astone, it works stable before and after the patch).

Probably related to memory management, left a comment in the PR.

Probably related to memory management

Yes, can we do something?

I am not an experienced JS/Obj-С/VST developer really and my capabilities in this are rather superficial. I want to write several VST2 sequencer plugins with a nice interface with minimal effort, I think your framework would suit me, I like its minimalism and the size of the final files, and the ease of assembly, but its current stability scares me. It looks like there are serious problems with different OSs/DAWs.

What PR? I don't see anything new here

It looks like there are serious problems with different OSs/DAWs.

Please create new GitHub issues for those and I'll have a look asap.

DPF has been around for quite some time and there are several plugins released with it, its VST2 support should be stable at this point. Cannot say the same for the webview wrapper which is rather new and untested; take stability with a grain of salt... The only other framework that deals with web views I am aware of is iPlug2. But it is also rather new as of 2021.

I haven't had time lately to continue working on this but the current feature set is complete and has some degree of testing on various DAWs on the three platforms. I have some plans for new features like http support, for allowing remote UIs...

Do you see the code review here ? removing [urlObj release] in CocoaWebView.mm @ 120 will probably fix the issue.

Wow, yes! That fixes the crashes. Will update the PR.

Well, these my problems on mac were only reason at the moment. I looked into the bugs list in the hiphop repository and saw something about crashes on windows. I have not tried this yet, but any crashes are bad. Live It is not clear whether this affects any created on hiphop plugins or just some use case. Live on Windows is one of the most popular DAW / OS combinations and I want to be calm about it.

Do you see the code review here ?

Nope, I can't see anything here. Maybe you should commit/publish your code review somehow? Didn't use it for a long time.

The only other framework that deals with web views I am aware of is iPlug2.

I will check, thanks! I'm also researching this thing on top of JUCE, it looks good but more complicated. All I need for a sequencer is to transmit midi notes by some events, I think any such framework should handle this. I think I'll start with yours and move on to another in the process if I suddenly need some functions or it doesn't suit me.

By the way, I wanted to know if I can compile a single universal ARM/x64 compatible binary plugin for Mac OS? If yes, then how? Looks like I can make like here, but I don't really understand what I need to do with Wasmer (it's x64 hardcoded)

I agree crashes are a very bad thing, particularly in a plugin context because a faulty plugin can bring down the entire host if it does not implement isolation. So all issue reports are welcome and take priority over new features.

I really do not master GitHub and also it is becoming more convoluted over time. Not sure what happened to the code review, it should be accesible from the PR.

I started this project because could not find a multiplatform web view that is suitable for use in a plugin environment. Creating the web views was challenging but the result works and looks very promising for real plugins. I'd be happy if someone also ported the web views to JUCE or iPlug2. I picked DPF because it is a minimalistic framework that does not depend on any proprietary plugin SDKs. I personally like that and Hip-Hop builds on that philosophy.

I cannot think of a reason why the web view shouldn't compile on M1, it is just the Makefiles are not adapted to it and yes they contain hardcoded x64 stuff. If you need WebAssembly DSP support then the Makefile should download the right static library (see WASMER_PKG_FILE), if not just do not define HIPHOP_AS_DSP_PATH and the Makefile will not try to download Wasmer or link against it.

What happens when running make without arch -x86_64 ?

I personally like that and Hip-Hop builds on that philosophy.

That's nice, but it supports only VST2 and rare LV2. I might want to have more supported formats in future. I don't care about VST3 actually if VST2 works fine, but AU / AAX is pretty useful for macOS users.

I cannot think of a reason why the web view shouldn't compile on M1...

There is no reason here, just compilers are able to assemble one universal binary from separate x64 and ARM so that the user does not download the version for his platform. I'm not sure how it works now, I tried it and it stopped on the platform-specific Wasmer build. I need to see how Wasmer is used here, I'm not sure if I need it now.

It will just build the ARM64 version but I use Live host in x64 (for all my old plugins) and it won't work. Now it builds x64, but I would like to make a universal build.

Oh, it works without wasmer!

Great, looks like the effort for getting universal binaries is low because M1 binaries can be already built. I didn't know that... Will revisit this soon, at this point it is expected many Mac developers already own a M1-based computer.

DPF has an AudioUnit branch but seems abandoned, I'd really like support for AU as well but requires a considerable effort. Unfortunately I don't have the time to contribute to DPF itself so I'm favoring new features on top of it.

I suggest checking iPlug2. It is under active development and I think it comes from the same people involved in REAPER. One of its examples is an experiment with a web view.
Similar effort but on top of JUCE tomduncalf_juce_web_ui
Then there is a related project called react-juce that allows JUCE projects to create UIs with React.js. I think it does not run a web view but allows writing JavaScript at least.

thanks for this review! I will definitely check it out

Hi @Tolsi FYI the hiphop project now creates macOS universal binaries by default and also supports VST3. The latter is only missing a pull request to be merged into DPF (#360). Meanwhile this fork is available https://github.com/lucianoiam/DPF/tree/develop.
