هذا امتداد لتنسيق ملف MPEG-ISOBase Media Format BitStream Library https://github.com/dicomj/mpeg-isobase. يرجى العثور على مزيد من التفاصيل هناك.
إذا كنت ترغب في التحقق من مكتبة MPEG-MP4 وبناءها ، فسيكون الإجراء كما يلي (يتطلب برنامج التحويل البرمجي C ++ 17 الحديث):
تحقق من MPEG-MP4
git clone [email protected]:DicomJ/mpeg-mp4.git mpeg-mp4بناء MPEG-MP4
