各位大大好
因为我有过大的视频文件想要用 ffmpeg 分割，但是一直出现问题，请各位指点。
这个视频文件的分析结果是：
Guessed Channel Layout for Input Stream #0.1 : stereo
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Fast.mp4':
Metadata:
major_brand : isom
minor_version : 1

Metadata:

handler_name : Sound Media Handler
At least one output file must be specified
分割时我使用的命令是：
ffmpeg -ss 00:00:00 -i Fast.mp4 -vcodec copy -acodec copy -t 00:10:00 test_fast.mp4
但是得到反馈：
[NULL @ 0xdf7940] Unable to find a suitable output format for 'test_fast.mp4'
test_fast.mp4: Invalid argument
因为根据结果，mp4 文件分析以及 ffmpeg -codecs 来看，我一直以为是因为缺乏和原始文件一样的 h264 编码支持，所以无法顺利使用复制分割。可是也有人说，因为不需重新编码，所以即使没有 h264 的编码器，也是无所谓的。那到底要怎样才能使用 ffmpeg 来分割视频呢？
我的环境是 openSUSE 13.2.
使用的 ffmpeg 是 3.0.3 ,ffmpeg -version 信息如下：
