VitamioBundle
VitamioBundle هي مكتبة مشغل وسائط وإطار عمل للتشغيل لنظام Android مصمم لفك تشفير وعرض محتوى الصوت والفيديو عالي الأداء. توفر وحدة فك ترميز فيديو مسرعة بالأجهزة لتقليل حمل المعالج واستهلاك البطارية على الأجهزة المحمولة.
يتضمن المشروع عميل بث بمعدل بت تكيفي (adaptive bitrate) يقوم بضبط جودة الفيديو في الوقت الفعلي بناءً على ظروف الشبكة لمنع انقطاع التشغيل. كما يتميز بمحرك عرض فيديو قادر على تكوين تنسيقات البكسل ومخرجات الألوان لتحسين الجودة البصرية للشاشات المحمولة.
تغطي المكتبة قدرات وسائط متعددة واسعة، بما في ذلك إدارة الترجمة، والتحكم في سرعة التشغيل، واستخدام رؤوس HTTP مخصصة لتحميل البث. وتدعم بث الوسائط الآمن عبر SSL وTLS وHTTPS المدمج، وتستخدم التخزين المؤقت المحلي لتقليل استخدام النطاق الترددي.
