13.2 Beta: Transition to Rendezvous Guest Crash

macOS 10.14.6
13.2 Beta 1

When you transition with any option besides Cut or Smooth to a shot with an active Rendezvous guest layer, it crashes Wirecast with the following:

 

Crashed Thread:        83

Exception Type:        EXC_BAD_ACCESS (SIGSEGV)
Exception Codes:       KERN_INVALID_ADDRESS at 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY

Termination Signal:    Segmentation fault: 11
Termination Reason:    Namespace SIGNAL, Code 0xb
Terminating Process:   exc handler [4494]

-This happens when using the Spacebar or the "Go" arrow button to make the transition.
-I tested the Cross Dissolve and Cross Blur and they cause the crash.
-Cut/Smooth do NOT cause the crash.
-Crash happens in default mode, AutoLive, and Live/Preview Swap mode
- If the Rendezvous guest is connected on the shot being transitioned to, the crash happens
- If the Rendezvous guest is disconnected on the shot being transitioned to, the crash does NOT happen
-This crash still happens if the Rendezvous guest is on the shot but their video or audio layer are turned off
-This crash also happened on transitioning from a Media File shot to an NDI shot while Rendezvous guests were connected (there was no Rendezvous guest on either shot, they were just in the project)
-The crash did NOT happen on transitioning from a Media File shot to an NDI shot with no Rendezvous guests

    macOS 10.14.6
    13.2 Beta 1
    IMac Pro
    Rendezvous Guest, Screen Capture, Video Media file.
    Used both Cross Dissolve and Cross Blur to/from Rendezvous guest to each of the other shots.
    Back and forth multiple times no issue.
    Perhaps there's another variable? Hardware?

    The crash thread 83 would be significant to show.

    FYI - I was unable to replicate as well. However, a friend tried this on Windows, and it dies for him on Rendezvous transitions as well... There is something there, just not enough data yet.

    I submitted probably a dozen crash reports, not sure if there's a good way to tie those to this.

    Bryce Seifert If you sent them to us you'd have an option to create a ticket or add to an existing case.

  • I think this is a similar issue https://telestreamforum.forumbee.com/t/m1hx6am/13-2-windows-crashing-after-rendezvous

    FWIW, I am now unable to re-create it–either with a new project or a previous project that had crashed. But the 1st day of the beta, it was constant. I uploaded some crash info on re-open for those, but those don't give you ticket numbers.

    Without a ticket, we can't follow up with the user as they may be anonymous.
    Also, crash reports when restarting may be the ones that go to Apple, no us.

    Nope - The ones DURING the crash go to apple. After restarting, they go to Telestream...

     Those are anonymous unless a ticket is created. While we can examine them we have no way to follow up with the customer.

  • Bryce Seifert : There is an issue in Wirecast 13.2 beta 1 where if you transition using anything other than Cut / Smooth and have Rendezvous Live Output enabled, a crash occurs.  This has now been fixed for the next beta.

    Thank you again for your feedback; this helped us narrow it down.

    • Simon Clarke Hey Simon, could this issue still be active in 14b?  I use transitions other than cut/smooth and have crashing issues in Rendezvous.
