Ffmpeg split video into multiple chunk but in different duration length

Question

I know how to split video into equal duration length, but here i want to split video into un-equal parts and number of parts and duration will be different for each time.

For ex, video length is 50 sec, i want to split it in 4 parts. 
1) 0 sec - 5 sec 
2) 6 sec - 22 sec
3) 23 sec - 34 sec
4) 35 sec - 50 sec

I assume you don't intend to leave one-second gaps out of the output files, right? So you really want 0-5, 5;01-22, 22;01-34, ... — L. Scott Johnson, Dec 18 '19 at 15:19

If you're capturing and segmenting all the input, use something like

ffmpeg -i input.mp4 -c copy -f segment -segment_times 0,5,22,34,50 output%d.mp4

It is not working, it creates blank video in different duration. – Vicky Dec 19 '19 at 04:07

Try with a different codec than "copy". Either leave off the `-c copy` altogether or specify your preferred encoding. – L. Scott Johnson Dec 19 '19 at 12:46

Ugh. Sorry. The `-vn` means no video. (A holdover from a different use of this). – L. Scott Johnson Dec 19 '19 at 12:48

If you looking for audio, then you can try this, modifying a version of @L. Scott Johnson

ffmpeg -i audio1.mp3 -c copy -f segment -segment_times 5,22,34,50 output%d.mp3
