Description
Reproduce command: ffmpeg.exe -i test.mpg
FFmpeg version: current
Output of ffmpeg:
[mpeg @ 01BF9760] max_analyze_duration 5000000 reached at 5016000
Input #0, mpeg, from 'F:\video\mtv\F0155301553685.mpg':

At least one output file must be specified
Problem: ffmpeg detected duration is 22:19:26.97, in fact it's 4min 17s. Mediainfo and players(VLC) detect it correctly.
