Can I publish live streams to Unreal Media Server with any other encoder than Unreal Live Server?
Yes, you can do it with any software/hardware encoder that sends streams in MMSH (MMS over HTTP) protocol. You can do it with Windows Media Encoder and VLC player, for example. Using Unreal Media Server configurator, you need to create a live broadcast of type “Rebroadcast stream from Microsoft Media Services” and supply mms link to pull stream from the encoder.
