Big, big thanks goes out to SVNPENN! After numerous program installs, nothing recognized the video, alot of time spent on this.

It literally took me 15mins to get this to work....it's basically spelled out for you here. Thank you once again!

Oh, & once i played the video on nbcolympics.com; video showed up in my youtube acct history, but will not play in youtube (says video "is not available in my country?!"); but there is a standard youtube address so maybe this can help others who know how to sniff it out from there. good luck.

I get the little flv segments, 1.7mb each... but would love a workaround to get the entire video... like they were getting with the steams in previous posts above.
Hi. Seems that some videos don't use that system. Try with other videos

However, I don't live in the US and am having trouble. I've bought a subscription to a VPN so I can access NBCOlympics, but I don't know if it's because I only have a VPN or what, but I am unable to download a full stream in 1080p.

Tried it and it stopped capturing after 1GB.

Do you know if there's a way I can resume the download? If not, if there's a way to capture the stream in parts (like maybe, every 30 minutes or maybe by every 500 MB, etc.) so that there's a lower risk of failure?

If you have a VPN, would you be able to check out european streaming sites (I think it's eurovisionsports.tv) and see if you can find a way for us to download the streams that way? Because the european sites don't use Youtube and I can't find the .m3u8 link when I try to do what your guide needs us to do.

Thanks again. In the meantime, I'll try again and see if I can finish downloading a stream.
Sad, I meet the same trouble as you, have you solved the problem? Hope someone could help us!

I can no longer download videos from July 30 or earlier. The videos still play like normal in a browser, but can no longer be downloaded. I would guess the videos are expiring in some way or other, and later days will eventually expire too, but it's strange because they still play like normal in a browser. Do they still work for anyone else?

Re: How to Capture stream of NBCOlympics.com


 
Hello, can someone help me out here..

I've been using the FFmpeg/m3u8 method to download videos from nbcolympics.com.

Everything has been working fine until now.

I can't seem to completely download this one stubborn video: http://www.nbcolympics.com/video/vol...vs-serbia.html

Everytime it gets to about 21:35 downloaded, FFmpeg stops and it gives an error.

Here is a screenshot of the error in FFmpeg: http://i49.tinypic.com/19xaw4.jpg

I have a feeling this can be fixed with a simple FFmpeg parameter but it's just a matter of an experienced user helping a non-experienced user out a bit. :)

Hey, by the way, if you seek to 21:35 into that video, an experienced user might be able to tell right off the bat why it stops abruptly.
