VEGAS Pro 15 cannot open openfx-misc (Win64)

[GlitchyPSIX]

Loading OFX plugins (Starting video plug-in factory, openfx-misc), VEGAS just crashes with Unhandled Exception (0x0000005), when using the builds from AppVeyor.

I can confirm this on Vegas 12 as well (also tested with mingw binaries). Note that it's only Misc.ofx that crashes, CImg.ofx loads fine.

I also tested with Resolve 15 (mingw and your AppVeyor binaries) and everything is fine.

Btw, I think OpenFX broke Vegas support some time ago. The plugins load, the parameters work, but you only get the source image in the viewer, or the render function never runs, I don't know. Can also confirm same behavior in openfx-arena (that at some point in time I used in Vegas 12). Not super important for me, but I though you should know.

CImg.ofx loads fine, but the preview changes nothing
Loading the binaries included with Natron directly in the OFX folder will load everything but crash VEGAS upon trying to show an effect.

Also, was openfx-arena privated? I can't seem to be able to access it anymore.

Hitfilm works fine in both VEGAS and Natron by the way so something's up...

You mean "Vegas broke OpenFX support"?

Those crashes are usually tracked down using the ofx Log (which is enabled when compiling plugins in debug mode.

Sometimes (eg with Resolve) the ofx log doesn't work and the only way is to use printf, or to disable the code from the rendering functions (getROD, getROI, render) using #if 0 and then gradually re-enabling it until the crash appears.

Since the crash happens at launch time, my guess is that it's simply that one plugin tries to get a host property which doesn't exist on Vegas, and thus throws an exception. This is easily fixed by setting the second parameter of propGet*() to false. If someone finds out which property is not supported by Vegas, please write it here and I'll document that in https://github.com/NatronGitHub/openfx-misc/blob/master/README-hosts.txt

It would be nice to have the full host description for Vegas: compile the Rectangle plugin with #define DEBUG_HOSTDESCRIPTION enabled.

For testing purposes, build the plugins separately (make nomulti)

I'll try, recently went down and installed VC++E 2010 to build with VS as I'm not experienced with building from MinGW/Cygwin

I was not referring to the crash when I wrote "OpenFX broke Vegas support". I was talking in general, since no plugins that uses https://github.com/NatronGitHub/openfx seems to do anything in Vegas anymore. They load, the parameters work, but the render action seems to do nothing(?).

[devernay]

As I wrote before, it's probably simply because of an unsupported property in Vegas. The ofx log helps a lot in this case.

[rodlie]

sure, I will do it tomorrow (getting late here).

I may be doing something wrong, but now I can't find the log. (Rectangle -- Compiled with MinGW, crashes upon selecting effect/generator)

Thanks @rodlie
OpenFX 1.1...
Now do you think you can find the unknown property that causes that exception?
@GlitchyPSIX on my mac, Sony Catalyst Edit puts the OFX log in /Applications.ofxTestLog.txt, so it can be anywhere in the filesystem... Look for a file called "ofxTestLog.txt" after runnin the plugins compiled in debug mode. The next solution is to launch vegas from cmd.sys, and do some printfs in the code. For testing purposes, you should compile each plugin individually. Makefiles do that, but I don't think it's in the VC++ project

[GlitchyPSIX]

Yeah, the VC++ project doesn't have the option to build separately, so I went with using MinGW-64
I'll run VEGAS from cmd and give you results once I get something
Oh no it appears I'll have some issues seeing the printfs

[devernay]

You should try with the newest appveyor artifacts. I just fixed a major bug in the openfx Support lib and added more compatibility
