21. Video in the Rapucation Site
• Don’t serve it from Plone
• It is stored in Plone (on the filesystem)
• Students can upload high res versions in any format
for the instrumental and full sung version

22. Use a Streaming Provider

thats-my-word,en,http://localhost:8080/rapucation/songs/thats-my-word,videoclip

23. Use a Streaming Provider
• Convert it to one default format and size
• Upload it to ftp.streamingprovider.com
• Update the song on the plone site with the correct video http-url
params = urllib.urlencode( {"status": status,
"mtype" : movie_type,
"file" : filename
})
set_url = auth_song_url + "/@@set_conversion_status?" + params
set_result = urllib.urlopen(set_url).read()
