[FFmpeg-user] How can I concat a video and audio to a longvideo?

[v]

I overcame it by using under a Linux system BUT:the result video is not correct,the attached audio is repeated manytime (My orignal video file is longer than the audio file).

Thank you.
  
 I have tried this but get such error:
  
 [AVFilterGraph @ 0252c240] No such filter: '[0:0]'
Error configuring filters.
  
  maybe the command is broken by line-break.How I can correct it?

I'm at the experimentation stage with ffmpeg as well, so.. ;o)

In the interests of same, I tried the following command,

ffmpeg -i video_file1.mp4 -i audio_file.m4a -filter_complex '[0:0]
[0:1] [0:0]  concat=n=2:v=1:a=1' -strict -2 combined.mp4

During the conversion I received,

[output stream 0:0 @ 0x1b27dc0] 100 buffers queued in output stream
0:0, something may be wrong.

in the console output, just after completion of video section, though
the conversion itself appeared to complete successfully.

While the two files were indeed concatenated in the combined file, the
video section repeated itself while the appended audio file was being
played!  Is this what happened when you tried it?

The version of mmpeg used was,

ffmpeg version N-63064-gb372f67 Copyright (c) 2000-2014 the FFmpeg
developers  built on May  9 2014 22:34:36 with gcc 4.9.0 (GCC)
