كيف أنشئ صفحة بث مباشر لموقعي؟

يمكنك الاستعانة ببعض السكريبتات التي تؤدي هذه الوظيفة، تجدها مجانية أو بمقابل، حيث تعمل هذه الأكواد على إنشاء فيديو مباشر على موقعك، ليُرى من قبل المستخدمين للموقع خاصك.

• VideoStream.php
• php-live-transcode
• FOS-Streaming

أيضا يمكنك استعمال live من خلال قناة على موقع يوتيوب وذلك بالستعانة بـ api Youtube.

فلإنشاء فيديو بشكل مباشر انطلاقا من موقع يوتيوب:
