Bài viết này sẽ hướng dẫn các bạn tạo script python sử dụng FFMPEG tạo hàng loạt video từ file mp3 và file ảnh làm background.
Nội dung Script
Script python này sẽ tìm kiếm file mp3 trong thư mục được chỉ định, tạo video và xóa file mp3 sau khi hoàn thành.

Áp dụng
Ví dụ mình sẽ tạo các thư mục như sau
- /tmp/create_video/mp3 #Thư mục để file mp3
- /tmp/create_video/image #Thư mục để file ảnh
- /tmp/create_video/video #Thư mục để file video
Liệt kê file trong các thư mục:
Thư mục để file mp3
[root@ITFROMZERO create_video]# ls -l mp3/ total 73760 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_10.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:55 test_1.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_2.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_3.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_4.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_5.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_6.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_7.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_8.mp3 -rw-r--r-- 1 root root 7550469 Jan 7 15:56 test_9.mp3

Sau khi tạo file thành công, các file mp3 đã bị xóa
[root@ITFROMZERO create_video]# ls -l mp3/ total 0
Như vậy mình đã hướng dẫn các bạn tạo video hàng hoạt bằng script python kết hợp ffmpeg. Chúc các bạn thành công.
