> ffmpeg -y -vsync 2 -i "concat:25.avi|50.avi" test.mp4

This produces an invalid file as FFmpeg does not create
fully compliant vfr mp4 files (that is at least what Baptiste,
the author of the relevant code, claims).

Please tell us more about the properties of your actual
input file to give us a chance to help you.
