No necesita Frameworks.

Pueden poner que la URL de Fembed se defina por GET o POST, eso queda a criterio. (Este código, solo funciona con Fembed)

Se puede adelantar el video. 👍 (Gracias al sistema de rangos)

¿Qué hace?
Descarga el video de Fembed (en memoria, no lo guarda) y lo va pasando al usuario constantemente. (Proxy)

Solo hay que copiar el código y guardarlo como PHP. 👍

Se puede usar hosting normal. (Aunque quizás se pare un poco)
