Which streaming video can I insert?

There are 3 types of extensions which are accepted: .mp4 / .m3u8 / .ism/manifest / .m3u8-aapl.
When the streaming link is invalid it will affect the local preview of the entire project and it will affect the viewing on the web player. Sometimes the web player streaming video can be blocked by the streaming website – this affects the entire VR project too (will load indefinitely). The streaming video MUST have the dimensions 16:9 – otherwise, it will be stretched in those dimensions.
