ViveDisplayExtractor crashes

[Erhannis]

Windows 10 Home, version 1511, 64-bit
Using the build from OSVR-Vive-build57-64bits.zip
Using the server installed by OSVR-SDK-v0.6-1363-g92d6d9d-build341-win-64bit.msi

When I run ViveDisplayExtractor, it crashes, without showing any output. When I click debug, Visual Studio reports to me the following error:

Unhandled exception at 0x00007FF68BC3F8CB in ViveDisplayExtractor.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

with the following, probably useless call stack:

>	ViveDisplayExtractor.exe!00007ff68bc3f8cb()	Unknown
 	ViveDisplayExtractor.exe!00007ff68bc39861()	Unknown
 	ViveDisplayExtractor.exe!00007ff68bc53903()	Unknown

When I try to start the OSVR server, it too crashes, debugging giving the following error:

Unhandled exception at 0x00007FF961E40BEB (com_osvr_Vive.dll) in osvr_server.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

with the following call stack:

 	com_osvr_Vive.dll!00007ff961e3365a()	Unknown

 	osvrServer.dll!osvr::server::ServerImpl::m_loop() Line 240	C++
 	osvrServer.dll!osvr::server::ServerImpl::start::__l8::<lambda>() Line 146	C++

It's possible that I'm using mismatched versions of the server and plugin, but I don't know how to match them. The server build numbers start at 171, and the vive build numbers stop at 57, so I figured those must not refer to the same thing.

hello Erhannis,

I meet the similar issue too, osvr server always crashed when I try to use it load com_osvr_vive.dll.

I've added some debug code and find it maybe caused by the latest driver_lighthouse.dll.

in DriverWrapper.h,

    /// This method must be called before calling
    /// startServerDeviceProvider()
    bool isHMDPresent() {
        if (!(foundDriver() && foundConfigDirs() && haveDriverLoaded())) {
            return false;
        }
        if (!loader_) {      <-- it will be crashed at here. 
            throw std::logic_error("Calls to isHMDPresent must occur "
                                   "before startServerDeviceProvider!");
        }
        return loader_->isHMDPresent(locations_.rootConfigDir);
    }

I remember that I've load this driver successfully before, but without any update in osvr side, it can't worked now. I've checked my driver_lighthouse.dll, the version date is 2017.01.04.

I think it maybe worked with the old version, but I can't find it.

hello Erhannis,

I find an old version of driver_lighthouse.dll(20160917), with this version, all the function can work well.

But I can't upload it to here, could you please leave your email at here, then I can share it with you via email.

[Erhannis]

Oh, thanks! Yeah, [email protected] should work. Do I overwrite the new driver with this older one, or just put this older one in a particular place?

[smallccn]

Hello Erhannis,

I send the old version via email, please refer it.

You can backup the new driver with another name, and pull the old one to the fixed path(Steam\steamapps\common\SteamVR\drivers), then it should be worked.

[Erhannis]

Thanks! I haven't tried it, yet, but hopefully soon I will find time.

Hi,

I've got a similar problem on windows 7 and would like to ask if anyone of you could send me the old driver, too? [email protected]
Best,

Hi,

Is there any progress on actually fixing the issue? I am also trying to get this to work.
What could I do to help?

@Erhannis ,

Please checkout the latest version of the plugin (also available for download at http://access.osvr.com/binary/vive), which fixes the DisplayExtractor crash along with updating to the latest OpenVR SDK version.
Let us know if you're still getting the crash when you run the latest version.

Thanks,
