Warning If you are looking at headless execution for integration with your CI server, please read our recommended Jenkins/CI setup without headless playback. Info Caution: Headless mode is available on Mac and Linux in Chrome 59+.
Do vst for windows work with mac. There are vst's made specifically for Mac. Just no AU's made for windows. I'm not aware of a wrapper that works for this either. Fxpansion made a wrapper but I believe it was for vst to AU or win vst to Mac vst. This may be the same thing the previous poster mentioned. Our website is packed full of free VST plugins, so we want to provide you with helpful information on how to properly install VST plugins onto your computer. How to Install VST Plugins on Windows. This video is for general installation of a VST plugin on your Windows computer.
This is fantastic. I'm using a combination of Chrome and PhantomJS for karma testing right now, for. There are hundreds of tests opening up hundreds of iframes and popup windows, and sending a lot of cross-window messages, and that ends up being really memory hungry. Chrome deals pretty well with garbage collection, so long as I'm careful to de-reference closed windows properly¹, and only uses a maximum of 150mbs.

PhantomJS eats up almost 6GB of memory before it's done, which makes it almost unusable on machines with less memory or CI boxes. Travis is a no-go. I'm hoping running Chrome in headless mode should give a nice speedup for our tests.
----- ¹ Turns out even a closed popup window or iframe keeps a huge amount of memory hanging around. After his announcement, Vitaly answered to the team: > >Is there interest on your side in adopting Chromium as a runtime?

Currently, PhantomJS heavily relies on Qt and QtWebKit. It's not that easy to adopt Chrome as a new runtime. > But I think we could implement PhantomJS as a completely new (with the same API) project that will use Chrome - Phantomium! A combination of: - Making sure all promises are fulfilled or rejected, so window objects don't get caught indefinitely in closure scope for any.then() or.catch() handler functions. - Using WeakMaps as much as possible, when we have things that are tied to a particular window, like message listeners or response handlers in post-robot - Manually clearing up any global references to windows when we destroy an xcomponent instance Finding the references was the tricky bit.
A lot of the effort was finding a leaky test-case, running in 100 times in succession, and deleting code until the memory graph was flat -- then figuring out what I'd just deleted that caused the leak. The problem started manifesting as I added more and more tests -- so now I'm actually checking my tests' memory usage on the fly and failing if they cross a threshold.
Hopefully that should avoid getting into this kind of sticky situation ever again. I've been testing Chrome headless extensively for the past few months, and while it's a good step, but it's not stable for high-volume or even diverse set of webpages. Memory usage is pretty high, lot of heavy webpages result in crashes/hangs, there are many inconsistencies between features available in full version and headless, their debugging protocol has different APIs that work on headless/non-headless in Linux or Windows, and so on. Of the bugs I've submitted, some have been fixed in the upcoming M59, so other critical ones may take longer due to their backlog. I suppose for now (maybe until M61-62), Chrome full with xvfb or even PhantomJS are better options. When you realize that Chrome is about the same size (by LoC) as the Linux kernel [1], you can't help but wish for a leaner & faster headless browser.
There seems to be some work going on building Firefox pure headless as well. Great overall, as long as all the browsers try to follow the RemoteDebug initiative [2]. I've been successfully using Chrome headless in a 500MB Docker container for dumping the DOM for for months (rendering a large variety of sites without restarts for weeks at a time) Run it with: --js-flags='--max_old_space_size=500' to force the VM to keep it GC'd below 500 Chrome v55 was a 30% memory savings, before that I used 1GB containers. It's not perfect, but I am definitely pushing high volume (multiple tabs, concurrent activity) and I am not having any significant stability issues and I am pushing diverse sets of webpages. I'm using more than one Chrome process so I can kill the processes every so often (e.g. After timeout or when they get stuck). Inside each Chrome instance I use 16 tabs, there might be a number of factors at play: - Are you worried about same-origin pollution if you run multiple tabs from the same origin in the same process?
If so -> Extra process - Do you have to take screenshots? You can only take screenshots of the tab that's in the foreground, so you have to activate it first to take the screenshot. This might fail if you have lots of tabs which roughly trigger at once.
You can see what I've built at btw. Yes, this exactly. I wrote Crabby [1] a few months back to schedule automated page testing using Chrome and webdriver but doing anything automated with Chrome is really atrocious. You can't expect to load more than one page every 10-15 seconds on the average 8GB instance and it occasionally crashes or otherwise stops working completely. I ended up writing a simple check using Go's net/http library to do basic performance profiling but it doesn't measure DOM loading like the Chrome checks do.
