Wirecast Drops during live stream

Hello,

Please let me know what could be the cause of drops during a live stream.  This is the second week I had dropped frames.  This week I had a total of 289 drops during our church live stream.  The internet is 300 up/down and is hard wired during streaming.  See attached computer specs and encoder setting for Facebook and Dacast RTMP.  Note Dacast recently changed their platform and now I am having all kinds of issues.  I used to chose DaCast in the output settings, now they are saying use RTMP and I have to set it up every Sunday. 

Any help you can provide on the dropped frames and how I can save the RTMP settings for Dacast so I don't have to set it up every time we are ready to go live?

  • Thanks for that.
    Have you updated to Wirecast 14.2.1? Please update and test with that version.
    What was CPU% (should be low with QuickSync though)?
    289 isn't a lot of dropped frames. Sometimes it can do that when starting the stream. so it's important to note when those frames dropped.

    DaCast is undergoing changes so it is best to use RTMP until we examine any API changes with them. You should be able to save the DaCast settings with your document. They have to have a persistent stream key and destination (confirm that with them).

    • CraigS yes I have the latest Wirecast update.  
      The CPU did not go over 20%; which was great but odd considering the number of drops.  In the past, I have not exceeded more than 5 dropped frames when live streaming.  But I was not using RTMP and Dacast had not updated their platform.  Never fails, when everything is going great, someone decides to make changes and settings, etc. no longer work.   
       

      The dropped frames were throughout the service.  More so when we added text to a lower third.  I was able to do this in the past with no problem.  
       

      Thanks, I will go back to them.  It’s been 4 weeks of working with them on the new platform.  I may have to leave them.  I appreciate your help.

      Regina Mays Is it possible you can do a test stream to Facebook only. That could confirm the issue is specific to DaCast.

    • CraigS good suggestion.  I will test with Facebook only and see what happens.  I’ll let you know the outcome.

    • CraigS hi Craig, I was able to test the Facebook only and yes the number of dropped frames continued.  That cancels out Dacast but doesn’t explain what is causing it.  Last Sunday I had over 800 dropped frames.  
       

      The number of frames seemed to drastically increase with the sermon bumper and recorded announcements.

    What codec are the bumper and the recorded announcements?
    What happens if you change the QuickSync Profile from Main to Baseline?

    • CraigS hi they are mp4 videos.  If I don’t touch the live stream there are no drops, but as I move lower thirds in/out, add other shots, etc. the drops went up rapidly.  I will test baseline instead of main for the profile and let you know.

     MP4 is a container. The codec can vary. H.264, H.265, etc..

    That might indicate an issue decoding the files or the fast change involved.

     That might give us a hint about an encoder issue if that's involved.

    • CraigS hi, I think it was x.264.  I’ll check and let you know.  I will also change the profile to baseline and see what happens.  I’ll let you know.
