20230806将ASF格式的视频转换为MP4

2023/8/6 18:47

缘起，自考中山大学的《计算机网络》，考试《数据库系统原理》的时候找到视频，由于个人的原因，使用字幕更加有学习效率！

由于【重型】的PR2023占用资源较多，速度较慢【占用硬件资源较大】。

剪映不识别ASF这个视频格式，只能使用MP4了。

于是ffmpeg登场了！当然将ASF转换为ts格式剪影应该也是可以支持的！

另：尝试使用MKVToolNix将ASF转换为MKV失败！

ffmpeg将常见视频格式转换为mp4

1，avi、mkv、mp4等格式转为mp4

ffmpeg -i 1.avi -c copy 1.mp4

2，wmv、asf等格式转为mp4

ffmpeg -i 1.asf 1.mp4
