Плавно воспроизводить видео с URL в утилите

0 голосов
/ 26 октября 2019

Я пытался воспроизвести видео в Recyclerview, но он не работает должным образом. Для этого я использовал: https://github.com/danylovolokh/VideoPlayerManager.

Может кто-нибудь, пожалуйста скажите мне альтернативное решение для того же.
