PHP stream remote video file

Let’s say I have a video on a remote server and this its url

“http://domain/video-path/video.mp4“

What is the correct way to stream this video using php with seekable..

I know how to stream the video using fopen and fread but it can’t seek with remote file

Answer

I’m using this, working both local & external video, seekable & resumable
