ffmpeg increases video segments length when used with -segment_time - how to fix?

Question

I am trying to record rtmp stream to file, splitting every 10 seconds.

My ffmpeg command is:

ffmpeg -i rtmp://192.168.16.82:1935 -f segment -strftime 1 -segment_time 10 -segment_format avi E:\record\CAM1_%Y-%m-%d_%H-%M-%S.avi

It works, but the created files are getting corrupted in some way. First file is OK, length is 10 sec; second file's length is 20 sec, and first 10 seconds is the static image; third file is 30 sec, and first 20 seconds are nothing but static image, and so on.

What I'm doing wrong?

AVI doesn't work with PTS, so you'll have to reset timestamps:

ffmpeg -i rtmp://192.168.16.82:1935 -f segment -strftime 1 -reset_timestamps 1 -segment_time 10 -segment_format avi E:\record\CAM1_%Y-%m-%d_%H-%M-%S.avi
