Fatal application exit errors

Ever since we upgraded to Wirecast 13.0.02 on our Windows 10 machine we are getting Fatal Application Exit errors when we close the program. We also are experiencing a high number of dropped frames, something we did not experience in previous versions. Any suggestions?

 

We are running Windows 10 on an Intel Core i7-3770K cpu at 3.5Ghz with 8Gb ROM and an Nvidia GeForce GT520 video card.

     That's a fairly old processor. Please check your CPU % and make sure it's comfortably under 80%

    Nvidia GeForce GT520 video card

     Please check and update the driver for the GPU.  That may be part of the issue.

  • CraigS CPU usages does not appear to exceed 50 percent. Usually hovers between 35-45.

  • Larry Badger The GPU driver updated? Include version number

  • The GPU driver version is 23 21 13 8846 dated 11/29/2017. Bios version is 75.19.24.0.0 . Ran the update function and it told us this is the latest version available.

       The dropout problem is occurring throughout the roughly 90-minute service (First United Methodist Church of Yuba City). Yesterday we had over 1,100. Problem seems to be worse when we run video and video with a text scroll overlay. An example is attached:

    Video is scrolling white text on green screen background running over a live camera shot. Settings on the video clip are:

  • Larry Badger Please include CDN and specific encoder preset or settings you're using in Wirecast.

  • CraigS Here are screenshots of the settings we are using. Our CDN is Boxcast

     

    The first is the preset we are using for recording in the computer. The second image is the RTMP setting for Boxcast and the third is the encoder we are using for the RTMP

  • Larry Badger It doesn't look like you're following their Wirecast integration recomendations

    Please stick to our presets as they point to. The keyframe rate is every 60 frames. You have 15 frames.

  • Larry Badger Additionally you're mixing recording and streaming frame rates 29.97 and 30fps. That can be another problem as well. Please keep to one frame rate.

  • CraigS Thank you for your comments. I will let you know where we are when I go through the setups again.

  • Larry Badger You're welcome of course. Our presets are optimized based on the CDN's recommendations.

  • CraigS  Since last time:

        Boxcast engineers reset our streaming settings by remote. They reset the keyframes to 2 saying it is easier on the system encoding.

        We eliminated video-on-video scrolling and now scroll video text over png/jpg images. The framing on the video is 29.97 and keyframes 30.

        We have disabled the recording in the computer and our cpu usage has dropped to 23 - 30 percent.

            Boxcast ran a 30-minute test and showed a dropout-free signal at their end.

        But the bottom line is we are still showing dropouts on our end, particularly when the scrolls are used, and we are seeing them frequently when we simply do a crossfade from one camera to another. Sunday we had a few even show up when the software was simply sending a static CDN pre-stream-start video.

         And the Fatal App Exit continues every time we close wirecast.

        We are running a shadow effect on our lower thirds type. Could this be part of the problem? I have seen others mention it related to this version of Wirecast.

        And while I'm at it, prior versions of Wirecast have allowed us to save the "deinterlace" settings on our camera inputs but this version will not save that., We have to reset each input every time we load Wirecast.

     How are you doing the scrolls (complete settings you mention the shadow)?
    Also, transition such as dissolves can cause a momentary spike in resources and bandwidth used so I'd need to know you upload bandwidth

     If you use Wirecast Help> Send Support Information it will send us your crash logs. Open a ticket if you don't have one already.

    That might be related to the input devices and the drivers so I'd need that information.

  • CraigS The scrolls are mp4s with white type and a black outline on the type set against a green-screen backdrop. They are produced using Sony (now Magix) Vegas and are 29.97 FPS. They have no shadowing. We are running them over a jpg image.

    The shadowing is on our Lower third name lines. We use only Wirecast type, no color backgrounds, no scrolling. We do not have NewBlue Titler.

    Our max upload bandwidth is 30 Mbps. Actual speed was 27.5 Mbps.

     Wirecast has two places where shadows can be added. Can you let me know which one?

    Disable it and see if it has any impact on drop frames or even the crash on exit.

     That might be part of the issue as well. Can you export from Vegas using Quicktime Animation codec (or ProRes 4444 but I suspect that's not supported)? They have alpha channels so it would eliminate chroma key plus the resources used to decode MP4 long GOP.

  • Shadow is applied in your second example, at text level. Turned it off on one slideand watched it for a bit. It helped but still dropped frames.

    Did file a support ticket (00703144). Trying to find out if we are licensed to used Titler, if that came with one of the auto upgrades. Haven't heard back.

    Fatal application exit errors continue, crashing the entire computer now whenever we close out Wirecast.

  • Larry Badger We've been including a free version of Titler Live for some time. The version you have depends on when you bought Wirecast.

    On or about January 22nd you were emailed information for Titler Live Express from us.
