Error with avidemux3_cli

[JP]

I installed avidemux 2.6.4 on my 64-bit CentOS system.  I ran this command, which should produce an output file consisting of 31 frames of video

avidemux3_cli --load IN.avi --begin 32 --end 62 --save OUT.avi

The input file is a raw format where each frame is stored in full (no inter-frame encoding).

The problem is the output video has all the original frames.  Nothing has been excluded.

How can I use avidemux3_cli to extract segments of a video file?
