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!
