Need help with tcp & udp stream for media player

since ue4 does not support udp/tcp stream url to set up a stream media player

RTSP over TCP and RTSP over UDP are supported by WmfMedia media on Windows. For a full list of supported streaming protocols, see https://docs.unrealengine.com/en-us/Engine/MediaFramework/TechReference

i found the udp messassing plugin

This has nothing to do with media streaming or generic UDP networking. The plug-in is a transport layer for the Unreal Message Bus, which is communication infrastructure for writing distributed applications in UE4.

i really don't know how to call any class from that plugin

That's because you're not supposed to. The implementation of the transport plug-in is hidden on purpose. Like I said, this is not what you're looking for anyway.

i'm super lost right now

Yes, it sounds like you have some reading to do on network programming in general and media streaming in particular. However, I suggest that you focus on a simple solution approach right now and learn more on these topics once you have more time.

this project has to be done for the next week

Setting up a proper RTSP media server is the way to go for you as there won't be any additional programming needed. If you cannot or do not want to set up a media server, you can also try streaming via HTTP or HTTPS. Both protocols are supported on Windows.

Some people had luck streaming from hosted cloud storage, such as Google Files and Dropbox. However, some advanced media features, such as seeking and fast forwarding may be unavailable. I would recommend it only as a proof of concept. Also keep in mind that you will need the direct URL to a media file, not some intermediate HTML page that redirects to the file. WMF will not understand those.
