Secondary Display Output Unstable

I currently have both a HP Elitebook Core i7 and a Apple MacBook Pro M1 running the latest version of Wirecast. I have had issues at the last three events I've broadcast with the new secondary display output. Two with the Windows 10 based PC and one with the MacbookPro. The issue I'm having is the output will go black and stay that way until I reset the Wirecast software. It shows video in the preview window via the secondary display output configuration menu but is sending black to the HDMI output. Also, last night the secondary output from the MacBook Pro would randomly turn its self off and the icon would deactivate and would need to be reset. It was not a hardware issue because the LiveU Solo I had connected would instantly show the home screen background. After the 3rd or 4th reset of the secondary display output it went black and actually crashed the entire system and caused the MacBook Pro to reset. Also last night after getting home I had issues sending audio to the HDMI output when running a test. I had to reset Wirecast after the first attempt to select the secondary output to get an audio output. I tested the HDMI out via an Apple brand AV splitter and a IO Gear splitter with both the same results last night. I never had the crash or audio issues with the windows based Wirecast but did have the black output with a reset needed to fix.

So having two totally different platforms with similar issues I would say the secondary output is not a stable means of broadcasting right now. Anyone else having these issues? I can't chance using Wirecast on paying gigs until this is fixed.

  • Wirecast 14.2.1? People sometimes miss updates so we always need version numbers.
    Secondary Display Live Output taken out of the computer how? 
    M1 MBP only has two Thunderbolt Ports
    HP Elitebook what is GPU and are you using HDMI out?
    Are the ports used only for the Display Out?
    What is on the other Thunderbolt port of the M1 MBP?
    Please explain what you mean by "reset Wirecast"
    Are you using Audio Device as well?
    What is system CPU% when this occurs?
    What is the video source(s) in the shot when this occurs?
    Are you also using Multi-Viewer Output at the same time?
    Do you have Live GPU Accelerated Icons enabled in Wirecast Preferences and if so is it highest or reduced?
    What other programs are running on the computer as that may impact GPU resources?
    Did you touch this button at any point as it will turn off the Display Out? 

    Please answer all the above in detail.

      14.2.1

      One port had a av splitter with power pass through. Charger in the USB C port, HDMI out to a LiveU Solo, a ethernet out to a ATEM Television Studio. Second port a EZ Cap HDMI running via USB 3.0 type C 1080i from the ATEM.

      Output was 720p to the LiveU.

      Icons are software defualt. Brand new computer and hasn't been changed. 

       

      CPU less than 20% the entire night.

      Only other program was the ATEM control software.

      Nothing was physically pressed via the TouchPad or keyboard. I watched the icon deactivate on it's own without any set pattern or operation of the software. The black output sometimes happens on the first attempt to output and has happened several minutes into a broadcast.

      Like I said it rebooted the MacBook Pro M1 after the 4th black output and reset.

      Very low CPU usage and nothing hogging the GPU at the time.

  • By reset I mean the black output requires the software to be closed out fully and reloaded back to the saved configuration. When the icon deactivated simply clicking it would start the output again. Two separate issues.

     I suspect splitting a TB3 port (they're TB3/USB4 ports with USB-C connectors). may be the issue. 

    As a Test, I suggest using only the built-in webcam and some media files and going TB3; USB=C) to a monitor directly and then testing Secondary Display Output reliability. Don't use the second port at all for this simple test.

     Thanks because there is a Reset procedure that involves deleting all preference settings.

      CraigS So I've had this same issue happening all of a sudden the last 48hrs. I engage the 'secondary display output' and like that it just displays a black screen on the second monitor.

      My setup: Mac Book Pro 16inch 2019 - Big Sur 111.6.1 - Wirecast 14.3.4 - only two usb c ports connected (one with power adapter, the other with second monitor).

      After a while of restarting Wirecast as well as my Mac and switching cables, removing any hubs from signal flow, testing all 4 usb c ports for the second monitor (all working fine).... I stumbled on what looks to be (temporary) fix, by doing the following:

      1. In Wirecast go to > Output > Secondary Display Live Output > Configure Displays...
      2. Then toggle between the options you have under 'Audio Device'....e.g if you had it previously set to 'None' then just pick any other device option from there.
      3. Click >OK. This fixed it for me.

      It somehow resets this area, gets rid of the black screen and brings back whatever feed/Mode you were sending to the Secondary Display. You can even go back and set the 'Audio Device' option (step 2) back to 'None' and it still works. You may need to do this every time you load Wirecast, I don't know.... as I have not yet shutdown my machine since figuring out this hack. Seems this area is buggy and needs some looking into.

  • hello 

    I have the issue that same as you 

    and then i have same system 

    zoom computer is window 10 (this is a the computer what gets signal from macbook m1) 

    wirecast computer is mac book air m1 

    I found that problem is occured when i connect hdmi through usb av hub 

    when i connect directly with usb c to hdmi to  zoom computer 

    woking well without self deactivate 

     

    I think m1 silicon versions's bug 

     

    telestream has to fix it !!

     That would mean the hub is the problem if direct connect works. We're finding that the reliability of hubs variable and would recommend against their use if they are causing problems.

     Please explain. Initial description is only two USB-C ports but then you describe removing hubs.

    Please explain what your setup is exactly when this issue occurs.
    I understand your steps to fix are but I need to confirm your hardware setup.

     This may need more information. Please explain.

      CraigS Yes, I did have a hub connected to one of my usb c ports and from the hub connecting via hdmi to secondary monitor. I removed the hub from the chain and went direct usb c cable to hdmi input on second monitor and issue was still occurring (so hub not the issue). Each time I pressed the 'output to secondary monitor' button in Wirecast it would just cause the screen to go full black. This is issue is now fixed for me, per the solution I described before.

     Thanks for that important confirmation.

    So it's every time you enable it after it's been setup?

     Seems more of a workaround since you shouldn't have to switch the audio back and forth. We'd want to check on that.

  • Hi, I was waiting for update, but but but.... WC15 Came out and "Secondary live output" is still an issue.

    I have two Macs setup with identical Anker USB-C to HDMI unit as hardware video out.

    Mac 1 - Graphics card: Radeon Pro 560X 4 GB
    Intel UHD Graphics 630 1536 MB

    with 2.6 GHz 6-Core Intel Core i7

    Works fine(ish) at least I can output live via Anker HDMI unit without WC14 going "black screen"

     

    Now on Mac 2 - Radeon Pro Vega 20 4GB Graphics card with 2.4 Ghz 8-Core i9 CPU.

    The WireCast, both on 14 and latest 15v is not working. Meaning as soon as I setup the "live ouput" function and click "OK" - then my Mac screen goes to black no externa output- nothing.

    I have to maually shut down WC App in order to get control back on the mac.

    The only difference between computers that I can see is Graphics card realy.

    I was really hoping that WC15 will solve this, but no, still same issue.

    So I have one Mac not usable for "LIVE OUTPUT".

    Thanks,


    Denis
