Wirecast Dropped Frames/Video Stops Streaming

During my stream, the "dropped" number will slowly increase and then at some point the video portion of the stream cuts out and it it says it's sending "0 kbps." Sometimes it cuts out after 15 minutes and sometimes it'll stream problem-free for two hours, but it usually cuts out at some point during my stream. To solve the problem in the moment, I just stop and start the stream.

 

My setup includes a HD camcorder with an HDMI cable running into a Magewell converter and then running into the USB port. I also have audio coming through via a second USB port.

 

Any solutions to this, so it doesn't keep dropping off?

  • I'd like to help but there's not enough information. It could be an older version of Wirecast, an issue with certain source files. CPU or encoder related. 

    Please do read READ BEFORE POSTING at the top of this product forum. We endeavor to trouble shoot this as quickly as possible so including complete details reduces a lot of back and forth questions.

  • Sorry for not giving more information. I am using Wirecast 8. I am so knew to this and not a tech person at all, so I am not sure what is relevant. My processor is an Intel (R) Core(TM) i7-6700HQ CPU @ 2.60GHz with installed memory of 16.0 GB. I don't know if that's relevant or not. Is that helpful?

  • Mark Janzen What is your upload speed using this app?
    Also what encoder setting are you using?
    Speed vs data rate can be a cause of dropped frames.

  • Mark Janzen can you post a screenshot of the upload speed test results as well?

     

    Can you test using x264 instead of MainConcept?
    Is your CDN asking for Keyframed aligned? I see that in your setting and usually that's not enabled unless requested/required.

  • Here is a screen shot. The app you sent me continually crashed and wouldn't test, so i tried a different one.

    I got a screenshot from our stream provider for the settings and was asked to duplicate that. Not sure it's required. It was just what had been checked.

  • CraigS I tried both of those options you suggested and the same problems continue. Any further ideas. Like before, it went 2 hours without any issues and then suddenly the stream dropped off three times in 30 minutes.

  • Mark Janzen As a test try going to a different CDN. It could be a free Ustream account for example. Try a document just using a webcam for example.

    That it's happening after two hours sounds like it's accumulative issue with settings, ISP, CDN since those are the only points that might change over time (outside of a memory leak).

    Since you have an i7 CPU you can also try Intel QuickSync (again examining the possibility this is an encoder issue) but it you're seeing this with both MainConcept and x264 it would seem less likely that the encoder is at issue.

    BTW you had indicated 39mbps up originally and your test shows 11.5mbps. Is it possible your speed is fluctuating over time? Or perhaps there's a data cap? These are all potential issues.

    Like
  • CraigS So, I tried streaming to a different CDN and the results were the same. I also tried Intel QuickSync and still I am getting the a number coming up under "dropped." Do you have any other possible solutions? Could it be something that is not synced with my camera and wirecast somehow? I just am at a bit of a loss as to how to solve the issue. Thanks!

  • Mark Janzen As a test use a new document with only a webcam and just do a local recording with an MP4 preset.

    Reset Wirecast Preferences as well before running the test. Wirecast > Help > Send Support Information but click on the lower left Reset Preferences.

    That will remove the potential impact of any source issues or internet connection or server issues. Make sure you're using a fast drive, at least USB3 and 7200rpm but SSD or RAID0 is even better.

      Icewasbest Keep in mind he was on a much older version of Wirecast and hasn't posted to the thread in three years. You may not have the same issue.

       Please explain exactly what you mean by "stopping" as that can mean several different things.

      Icewasbest said:

      ISPs promise speeds but don't always deliver. You'd need to include the results of a speed test and especially upload and packet lose results.

      CraigS Hi Craig

      So what i mean with stopping is that sometimes when i do a livestream to an example youtube bc it mean more information it says that wirecast send not enough kilobyte (1600) when on wirecast its supposed to send 4 mb and sometimes wirecast stop sending instantly and all rendez vous are closed except that rendez vous is still on for other people since im using rendez vous on my other computer meanwhile and it still work while on my main it doesn't sometimes it can stay like 5 hour without interruption sometimes it stop the stream 30 minutes after the begginig sometimes later. 

      i forgot to mention that i use the internet cable its the first time i use it since my computer dont have a wifi card

      Speed test:

     The data rate set in the encoder is a target and it can vary by content. That generally wouldn't stop the stream. 

    Your upload test looks good enough to go to Facebook and YouTube at the same time without bandwidth issues.

    Icewasbest said:
    sometimes wirecast stop sending instantly

     Sorry but it's not clear how you're determining this. 

    Icewasbest said:
    all rendez vous are closed except that rendez vous is still on for other people since im using rendez vous on my other computer

     This may be a different issue. 

    I'm sorry but it's unclear what you're doing and what is happening.

    You need to describe step by step with a clear description so that we could repeat the steps. 

    You may need to take screenshots or do a screen recording showing what is happening.

      CraigS Ok sorry for mis understanding

      So first of all i i go on wirecast make the rtmp and facebook live ready

      then before the live begin we always use rendez vous 2-5 people

      when i am in the LiveStream for a moment everything is normal the live is clear and everything but i do get notification saying the sending is low

      (translation: ur current flow (1676,29 kbit/S) is inferior to the recommend flow. we recommend you to use a flow of 4500 Kbit/s.

      but that dont really bother me since the video still goes but when i keep going its like litterally the internet stop for wirecast like imagine you'r computer get no internet instantly well that what happend so at the end my stream stop sending any signal to youtube/facebook and i dont see the Rendez Vous guests anymore. Like litteraly Wirecast Receive No internet and send no internet and the only way fix it is to wait a long time or restart Wirecast . and i was thinking maybe there is a problem with my internet but i dont think because when it stop on my computer it works on other devices . if needed i can give you teamview if needed so you can maybe find the problem because whatever i do i dont find it. i hope i was able to make you understand better 

      (My main computer is a windows 10)

      (i use a macbook as other device to connect the Airpods so that the animator can listen to the guests)

      (right now im doing this by putting some 24/24 h livestream with wirecast to see if maybe it got something to do with time but right now it seems not but i still keep doing it)

      (it happend to me in the past when i was on the same computer but i was using 1.13 so i dont think its not the version)

      (i tried changing of cable of ethernet but no change and since it got no wifi card i can't try with it)

      (we are actually unable to put a wifi card bc all stores are closed bc of corona)

     You mention Facebook but I think you mean YouTube. Yes Youtube will sometimes show that. As long as Wirecast streaming icon is green and the stream can be viewed on another computer it's good.

     I would do a speed test at that moment. Providers can have temporary problems. If Wirecast loses connection to the internet its stream icon would go red with a line through it.

     

    Icewasbest said:
    f needed i can give you teamview

     You would need to contact premium support for that. You should do that if you have premium support. If the internet has a problem then TeamViewer would also not work though.

     its what it does a red line on the wirecast logo on the deskstop

     As soon as that happens do a speed test.
    That is caused usually by either a bad internet connection or an issue at the server.
