推荐答案

它不起作用，因为"webm"文件格式不支持"concat协议"(也称为二进制concat).avi，mpeg-ts支持该功能.请找到 FFMPEG Concat 文档对此进行详细讨论.

It is not working because the 'concat protocol' (also called as binary concat) is not supported for 'webm' file format. It is supported for avi, mpeg-ts. Please find the FFMPEG Concat documentation talks about this in detail.

解决方案:如上述文档所述，您可以使用以下更为灵活的"concat demuxer":

Solution: As mentioned in above document, you can use the 'concat demuxer' which is more flexible as below:

ffmpeg -f concat -i mylist.txt -c copy output


Where mylist.txt is something like:

# this is a comment
file '/path/to/file1'
file '/path/to/file2'
file '/path/to/file3'

在当前目录中合并2个mp4文件(video1.mp4和video2.mp4)的示例.

Example of combining 2 mp4 files (video1.mp4 and video2.mp4) in current directory.

ffmpeg命令:

ffmpeg -f concat -i filelist.txt -c copy output.mp4

"filelist.txt"的内容

content of 'filelist.txt'

file 'video1.mp4'
file 'video2.mp4'

级联的视频可用@ output.mp4

concatenated videos available @ output.mp4
