How to download only specific time frame

[aliv]

Hi, I have one video which duration is 167 minutes (very long!), because I have limited bandwidth I would like to only download the HD version but only in a specific time frame (for example from 10.00 - 30.00). Is there anyways for me to do it? (for example by using ffmpeg)

The video is

http://concert.arte.tv/fr/soiree-exceptionnelle-nicolas-le-riche-lopera-de-paris

I already have the direct link

http://artestras.vo.llnwd.net/v2/am/ALW/054000/054800/054818-001-A_SQ_0_VO_01370342_MP4-2200_AMM-ALW.mp4

and the m3u8 link

Thank you!

For http progressive download you can use the direct link URL

ffmpeg -ss 00:10:00 -i "http://artestras.vo.llnwd.net/v2/am/ALW/054000/054800/054818-001-A_SQ_0_VO_01370342_MP4-2200_AMM-ALW.mp4" -c:v copy -c:a copy -t 00:20:00 output.mp4

Hi poisondeathray,

This showed up when I downloaded using your suggestion (the video result is HD but it stopped around 2+ minutes).

Do you know what's wrong? Thanks

Maybe you have bad internet connection ? Disconnect? It worked ok here.

Not sure how to "resume" with ffmpeg

Yes you're right, I tried again and it worked. Thanks!
