Known MvnCaster Issues

If you aren’t familiar with the name MvnCaster, it is the name of our built in broadcast tool. You can find it by clicking the red Go LIVE Now button at the top of our sites (excluding

Recently we rolled out a new MvnCaster to replace the old Flash based one. Right now it’s in Experimental phase of development due to many browsers implementing WebRTC differently. So far the most stable and RFC compliant implementation is with Google Chrome. Although it does work with Firefox, too.

There are some known issues with the new MvnCaster, here is a list (in no specific order):

  • Audio playback on the Go LIVE Now page causing an echo
  • No video device (black screen) even though webcam is hooked up
  • Getting kicked off air as soon as you start broadcast (we believe this is associated with the no video device error above)
  • Doesn’t work on latest version of Opera or Microsoft Edge
  • Only works in Safari on iOS (iPhone/iPad)

These issues are being addressed and will be rolling out bug fixes to (hopefully) address these known issues. Although the Micrsoft Edge issue may be last on the list due to how broken their WebRTC implementation is.

If you have any questions or experience any issues, please visit Tech Corner and one of our awesome volunteer Tech’s will do what they can to help you!

Flash Is Dead

We have officially shut down our Flash video servers and removed all Flash video players from our sites. If you’re a viewer and use a computer that is less than ten years old, you likely won’t notice anything.



If you’re a broadcaster and your stream isn’t viewable anymore, you will need to update your encoder settings (or even your encoder. Note: Free version of XSplit does not work due to its audio codec.) We recommend using OBS Studio (it’s free and awesome!) [ ]

Here are the basic encoder settings required:

  • Video codec: H.264/x264
  • Profile: Baseline, Main, or High (preferably High)
  • FPS: 30 or 60. Not 29.9, not 50. If you do not use either 30 or 60, expect your viewers to have playback issues on your stream.
  • Video resolution: Any 16:9 ratio should work (Examples: 640×360, 1280×720, 1920×1080). We suggest starting with 640×360
  • Video Bitrate: This depends on your upload speed and the video resolution used in your encoder. We usually suggest 350Kbps to 500Kbps for 640×360 to start out with. Keep in mind that the higher the video bitrate you use, the less likely folks with bad internet will be able to watch your stream.
  • Audio codec: AAC or MP3

Note: If you use a high video resolution in your encoder with a low bitrate, you are likely to have playback issues.


Watching Streams

There is a small group of folks that still use Windows XP. Browser development and updates for Windows XP stopped years ago, meaning the new HTML5 features that modern browsers support, are not supported in Windows XP. So what does that mean for Windows XP users? With Flash removed, they will no longer be able to watch streams on our sites. In fact, they won’t be able to watch HTML5 live streams on any site on the internet since all major websites are dropping Flash. Not to mention that Adobe (the owner of Flash) is officially ending Flash soon.

TL;DR: If you use Windows XP to watch our streams, you’re going to need to use a computer that isn’t old enough to join the military. Sorry.
