# تنزيل محتوى فيديو HappyHorse

> نزّل ملف MP4 المكتمل لمهمة فيديو HappyHorse عبر مسار المحتوى.

استخدم نقطة النهاية هذه لتنزيل ملف MP4 لمهمة فيديو HappyHorse مكتملة. إذا كانت المهمة لا تزال قيد التشغيل، فستُرجع API خطأ JSON بدلًا من بيانات الفيديو الثنائية.

## قبل التنزيل

* أنشئ مهمة باستخدام [إنشاء فيديو HappyHorse](./create).
* نفّذ الاستطلاع باستخدام [استرجاع فيديو HappyHorse](./retrieve) حتى تصبح قيمة `status` هي `completed`.
* مرّر معرّف المهمة نفسه إلى نقطة النهاية هذه.

## تخزين الوسائط المكتملة

يكون نص الاستجابة عبارة عن محتوى ثنائي `video/mp4`. احفظ هذه البيانات في وحدة التخزين الخاصة بك عندما يحتاج تطبيقك إلى وصول دائم إلى الوسائط المُولَّدة.
