Tôi đang sử dụng lệnh này để chuyển đổi video từ M4V và AVI sang FLV:
ffmpeg -i 'video_1355440448.m4v' -s '640x360' -ab '64k' -ar '44100' -q:v '1' -f 'flv' -y video_1355440448.flv
Tôi có hai máy chủ:
- một máy chủ với phiên bản FFmpeg N-48249-g5079568, trong đó các video hoạt động tốt.
- một máy chủ khác có phiên bản FFmpeg N-48332-gfe5a2fc, trong đó các video không hoạt động tốt.
Không có lỗi trong cả hai máy chủ và cả hai máy chủ đều chuyển đổi video có cùng kích thước. Nếu tôi nhấp để phát video này, nó sẽ tạm dừng để đệm và bắt đầu sau 30 giây hoặc lâu hơn.
Một máy chủ hiển thị phần nào được tải với một đường màu đen, nhưng máy chủ khác không hiển thị phần này.
Tôi đã tìm thấy một cái gì đó Một máy chủ có
