Không có video nào được viết trong một số phần của video như phân đoạn từ FFmpeg

Tôi đang phân đoạn một video dài 20 phút thành hàng trăm clip nhỏ. Lệnh này giống như

ffmpeg\\ffmpeg -i nx_1.avi -ss 399.37 -t 1 ka1_2.avi

Các ffmpeg là trong một thư mục con.

Nó hoạt động rất tốt cho hầu hết các tập tin video của tôi. Vấn đề là một tệp, đối với tệp đó, một số clip được phân đoạn chỉ có âm thanh, video có liên quan rõ ràng không được ghi vào clip. (Đính kèm tệp nhật ký bên dưới.). Nhưng các đoạn được phân đoạn trong phần khác của video là tốt. Cả âm thanh và video đều ổn. Tôi đã cố gắng phân đoạn một đoạn clip dài hơn để bao quanh phần có vấn đề của video gốc và phát lại nó. Đoạn clip phát tốt cho đến khi phần có vấn đề, nó bị đóng băng ở phần đầu của vấn đề.

Tôi sử dụng ffprobe để thăm dò avi, nó nói chỉ số ODML không hợp lệ. Tôi đoán đây là vấn đề.

Làm thế nào tôi có thể giải quyết vấn đề này?
