我想将此 AVI 文件的容器更改为 MKV，无需编码。
ffmpeg -i Killing.Time.S01E01.HUN.WEB-DL.XviD-DART.avi -c:v copy -c:a copy Killing.Time.S01E01.HUN.WEB-DL.XviD-DART.mkv
尝试了这个命令，但是它不起作用。:(

Stream #0:0 -> #0:0 (copy)

答案1
AVI 没有可供转换的内部时间戳，使用 -fflags +genpts 让 ffmpeg 创建它们。
ffmpeg -fflags +genpts -i input.avi -c:v copy -c:a copy output.mkv
