facebook displays green screen

Facebook displays GREEN.  But wirecast was showing that the live output was correct. 

First time this has happened. Using 10.0; streaming to Facebook Live and RTMP for Twitter / Periscope. About 1 hour into the broadcast the destination was displaying a full green screen - as per the image. On the wirecast side it was displaying images being sent to Facebook but the resulting image was just green. I unplugged cameras and re-added them but the same thing was appearing on facebook - unsure why. I had to stop the stream and restart, which worked but not ideal during a sport event.  I had streamed successfully for 1 hour before this with no issues. 

Ive a powerful laptop and everything was done correctly so. 

 

Any help appreciated

  • Update to Wirecast 10.1. Do a local recording as well. That will confirm that Wirecast encoder is working properly. It's quite possible there's an issue on Facebook's side.

  • This happens with more than just Facebook. I have several machines that this happens to...Windows 10...running WC8.2  Happens randomly across different machines. The live and preview screens show fine, but all recordings are Green. 

    Usually a reboot resolves the issue, however, since it is across different computers and different hardwares, it has to be a WC issue.

  • Tony Addotta does it happen after a period of time? Mine is usually about the 60 min mark. WC is showing cameras operating and outputting but the end result is green screen. Or black. Both on WC 9 and WC 10. Bizarrely the audio, which is on a different level is working fine. Which camera to hdmi converter do you use?

  • Tony Addotta when it was immediate with me it was my nvidia gpu drivers. But these are up to date now. I also use the magewell usb 3.0 to hdmi. Could be some correlation there. I’m still testing mine out for all errors.  Do you have multiple cameras coming in or just one?

  • Jamie stevenson doesn't matter what source I use. Camera or graphic feed. The thing that gets me is that it is completely random among 70 computers. Never know when it will happen..and trying to duplicate it is near impossible. Cannot determine if it's the magewell or the graphic driver..Nvidia 1050s..I have yet to see if this is happening on both magewell versions (driver or driverless). I'll be testing all week...if you see anything let me know..I'll update if I find anything.

    Thanks.

  • Tony Addotta There's been many updates since version 8.2. Facebook has also made changes since then. Please update to Wirecast 11 and test in a new document.

  • Jamie stevenson Please update. All fixes are relative to our current version. Update to Wirecast 11 and test with a new document. It does sound like you may have a hardware issue though.

  • CraigS As I said before, it is completely random. I will test with the newest version, but probably will not know anything for weeks.

  • Tony Addotta The audio is the same here,,,Get clear audio just a Green record. Unfortunately the only work around I have is to do a test record prior to go-live and checking the recording. If it is green then reboot, if not, then it "should" be good.

  • Tony Addotta It sounds like it might be a GPU or hardware related issue though. That's especially so given it's random. In order for use to investigate there'd usually be a pattern to an issue.

  • CraigS I understand that pattern would be needed,,however to speculate that 70 computers (some from different manufacturers and some different GPUS ) Could be a hardware or graphic card problem is a little hard to swallow.

  • Tony Addotta At first we thought the same thing, that it was only happening on x type computer systems. Then we received a call alerting us that it happened on a Y type computer (assuming that x and y are to different computer with different hardware).

  • Tony Addotta Perhaps there's something you have installed in all of them, A specific utility for example. Given the large number of computers running Wirecast we'd see this pervasively if it were a Wirecast only issue.

    One thing I'd do professionally is create a user account on each computer just for live streaming. This limits the impact of user account based issues that may have run software for other purposes.

  • CraigS There is only one user per machine Nothing gets run on these computers except for WC, a network analyzer for live streams, and all the WIN10 background processes, other than that they're clean . Standard windows 10 install. Now, are you saying that Telestream only test on a computer that only has windows installed and nothing else? No drivers for hardware, nothing to monitor the bandwidth, no diagnostic tools to help troubleshoot issues? Do you have a list of known software/hardware/or configurations that have issues with WC? I'm not disputing that it could be something that was installed or maybe uninstalled, or an update (Win10). Sorry,  I don't mean to sound adversarial, just frustrated. I'd be happy to share specs and take recommendations.

  • Tony Addotta We haven't experienced the issue. Some machines dedicated but we test on personal machines as well.

    You can report the issue but we need a means to duplicate it. Since this is only occurring some time into the stream it may indicate something changing over time or running in the background causing this. 

    Isolate one machine. Create a new Admin Account. Run using something simple like a webcam (no video input cards) and let it run for some hours and see if it occurs. Using X264 instead of QuickSync or NVENC to eliminate those encoders. You can eliminate internet entirely and just do a local recording.

  • CraigS Need to clarify, this does not happen some time into the stream..this is immediate on our systems. even if we change the source from vga (record, stop) to hdmi (record, stop) to sdi (record, stop), all three recordings are green. so far the only thing that has fixed it is a restart of wirecast.  

    This happens on local recording, using x264, on an external usb3.0 devices (Magewell)

    Please explain. Immediate when starting Wirecast, selecting a specific source or source time. In other words describe as a series of steps taken and when it occurs. I think there may be a pattern, even if intermittent. Rarely is something truly random. It may only appear random because the pattern isn't obvious.
    Please list the steps and describe at what point it would occur. Describe as if I was opening Wirecast for the first time on my computer for example.

     Already not random. That means a process is being stopped and then started. Restarting a process fixes the problem.

    Is this visible in Wirecast Live Broadcast Area?
    Does this only happen after your start recording?

  • Take computer out of case, setup peripherals (video capture equipment) We use a usb 3.0 Magewell device to pull in the feed. Start computer. Start Wirecast.  Connect source to device, (can see it in preview), send to live, (can see it in Live)..Hit record...

    End record, Check video file, Green from start to finish.

  • This issue generally will not be caught until the end of the recording day.

     So it displays OK in Wirecast but the recording is bad.
    That would inputs OK, Processing OK, Encoders problem.

    What encoder presets are you using (and is it x264, QuickSync, NVENC) and are they customized at all or just using presets as is?
