Kya Ghar Se Online Bhej Diya Hua Video Copyright Hai ya Public Domain?

Arre yaar, mere dost ne mujhe ghar se online bhej diya hai ek video jo kuch Bollywood song hai. Lekin maine dekha hai uske peechhe ek video hai jo beech mein aati hai, phir song start hota hai. Main sochta hun ki agar maine is video ko apni Facebook profile par post kiya, toh phir kya hoga? Kya ye mere liye copyright hai ya phir public domain ho gaya hai? Bas ek saadhaaran video hai, aisa nahi hai na phir bhi mera dost kaha hai ki ye copyright hai aur maine kuch kar le raha hun. Toh kya karne se pehle main janta hun ki kya hoga?

Ab batao, ye kya hoga?
