How to (most efficiently) download video from Periscope

Majority of the search results for "download periscope" lead to websites allowing me to download the app.

"download periscope stream" is a much better search term that actually led me to two solutions but none of them are convenient.

1) tried and works

http://www.quora.com/How-do-I-save-my-Periscope-video-or-broadcast-to-my-phone/answer/Andrew-Leyden – that requires that the phone is connected all the time

(for the whole 50 minutes of the stream)

2) didn't try, should work

Recording screen + using http://www.instructables.com/id/How-to-record-audio-from-your-computer-using-Quick/ to record audio

(again, 50 minutes waiting)

I also tried using technique described here – https://stackoverflow.com/questions/30073330/downloading-storing-periscope-live-streaming-broadcasts – just by observing network request and populating list of URLs to download via wget:

https://replay.periscope.tv/ ... ==/chunk_1.ts
https://replay.periscope.tv/ ... ==/chunk_2.ts


But that naive version fails – they check cookie… Maybe I should use PhantomJS to accept cookie and then download the chunks? Before I start digging into that – maybe there is a straightforward, off the bat, ready to go solution I'm missing?

The question is generic and applies to any periscope video.

Bonus question – what if the video is mine – can I retroactively save it to the camera roll from the periscope app? (assuming "autosave broadcast" option was turned off)
