I have found one backlogged issue about WebBrowser Unreal Engine Issues and Bug Tracker (UE-40342)
and one solution with unsupported VLC Plugin Live Stream in UE4 - Programming & Scripting - Unreal Engine Forums
Can anybody give some point of view on this stuff?
solved on 4.24: I cloned master (version of 13.12.2018) of the VLC Media Framework plugin and get URL m3u8 like here in the StreamMediaSource. but very interesting of integration h264 in UE systems (Media Player and Widget Browser).
hey thanks for your post! I noticed that the VLC plugin is very unstable and crashes a lot. And additionally it lacks hardware acceleration with kills performance. Did you still find it viable?
Yes, version above is very stable for receiving youtube live stream. In 4.24 I’m using it without any crashes.
