// example is 30 minits


AVCONV

avconv -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.avi
avconv -i input.avi -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.avi 
avconv -i input.avi -vcodec copy -acodec copy -ss 01:00:00 -t 00:30:00 output3.avi



~~~~~~~~~~~~~~~~~~

Or

avconv -ss 0 -i source.m4v -t 100 -vcodec copy -acodec copy part1.m4v
avconv -ss 100 -i source.m4v -t 100 -vcodec copy -acodec copy part2.m4v
avconv -ss 200 -i source.m4v -t 100 -vcodec copy -acodec copy part3.m4v 
avconv -ss 300 -i source.m4v -t 100 -vcodec copy -acodec copy part4.m4v

Or do some script like here: http://icephoenix.us/notes-for-myself/auto-splitting-video-file-in-equal-chunks-with-ffmpeg-and-python/

Code:

sudo apt-get install -y PiTiVi avidemux Kdenlive lives

I recomend using Kdenlive



 use Kdenlive, but I wouldn't be surprised if you could even slice video this way in PiTiVi:

    Create a new project with your full lecture.
    Set your start and end points for the first "manageable chunk" in the clip monitor.
    Drag from the video in the clip monitor down to your timeline. It will be just the chunk you chose.
    Set new start and end points in the clip monitor and repeat as needed.
