Solutions to streaming https mp4 video

Hi everyone, as the title said, I’ve been stuck for weeks researching ways to stream video mp4 from the HTTPS link, I found some packages but they require payment and a license because in this project I develop an SDK so I can’t use any packages from the asset store to apply this project. Right now I researching my way of streaming video, are there any solutions or ways to do this? Thank you all very much
