ffmpeg流文件合并concat

使用ffmpeg的concat可以实现简单的流文件合并功能。

 例如：

./ffmpeg -i concat:"out002.ts|out003.ts|out004.ts" -acodec copy -vcodec copy -f mp4 cat.mp4

注意： 输入的各个流需要编码参数一致，否则输出的文件会跟预期不同。

Physical concatenation protocol.

Allow to read and seek from many resource in sequence as if they were a unique resource.

A URL accepted by this protocol has the syntax:

concat:URL1|URL2|...|URLN

where URL1, URL2, ..., URLN are the urls of the resource to be concatenated, each one possibly specifying a distinct protocol.

For example to read a sequence of files split1.mpeg, split2.mpeg, split3.mpeg with ffplay use the command:

ffplay concat:split1.mpeg\|split2.mpeg\|split3.mpeg

Note that you may need to escape the character "|" which is special for many shells.
