ساخت ویدیو پلیر حرفه ای با جاوا اسکریپت ( لیست پخش ، پیش نمایش فریم )
ویدیو پلیر با جاوا اسکریپت – در این آموزش با javascript خالص بدون هیچ فریمورک و کتابخانه ای ویدیو پلیر حرفه ای و شخصی سازی شده ی خودمان را می سازیم .
ویدیو پلیر اختصاصی با امکان playlist و پیش نمایش هر فریم ثانیه را در زمان بردن ماوس بر روی seekbar را دارد .

لیست نظرات
سلام. میشه کاری کرد مسیر فایل روی سرور مخفی باشه یا کاری کرد که فیلم قابل دانلود نباشه؟
درود ، میشه این کار با استفاده از ساخت encode انحصاری برای ویدیو انجام داد . اما مبحث پیشرفته ای هست و توی چند تا مقاله نمیشه توضیح داد .
سلام وقتتون بخیر امکان استفاده از کد‌های مورد نظر برای وردپرس وجود داره؟
سلام بله
