thanks for this.

just as a heads up, this requires ffmpeg and json.

Usage

Save the file above to your system.

chmod +x periscope.sh
./periscope.sh TOKEN

You get the token by following the instructions in this post. Scroll down to the section that talks about getAccessPublic.

To make this work, you must change line 4, it seems.

curl -v "https://api.periscope.tv/api/v2/getAccessPublic?token=${TOKEN//=/%3D}" | json > periscope.json

becomes

curl -v "https://api.periscope.tv/api/v2/getAccessPublic?broadcast_id=${TOKEN//=/%3D}" | json > periscope.json

s/token/broadcast_id/ basically... for some reason it comes out looking worse than on the website, though.

I suggest changing the last two lines to these simpler ones (which also give the file a unique name), they take longer but they also don't touch the video quality:

ffmpeg -i playlist.m3u8 periscope$TOKEN.mp4
cp -v periscope$TOKEN.mp4 ..; cd ..; rm -frv periscope; file periscope$TOKEN.mp4

@byalextran: are those notes to yourself?
@tomck: i have found your comments just now, but your are quite right about s/token/broadcast_id/.
@byalextran, @tomck: have a look at the improved version!
