[FFmpeg-user] Why the fps of concatenate video file change with old video file?

2016-06-23 Thread cuizhe
I have two wmv video file which 25fps. I concatenate these video file using ffmpeg command line like this: >ffmpeg -r 25 -f concat -i 1.txt -c copy output.wmv 1.txt: file g:\1.wmv file g:\2.wmv It works. But the fps of output.wmv is 30. How can I maintain the fps of concatenate video file?
