downloading rtsp streams

python, vlc, rtsp, streaming, helpers

Downloading some recordings from the plone symposium east 2011 site.

There are some nice session recordings on


Problem: there are streamed, not downloadable. But I'd like to have them for watching while on the train etc.

What have I found out?

I manually took the ids of the recordings that were interesting to me from the respective pages that link to them, and wrote a script that scrapes the actual 'movie pages' for the stream url (it contains session titles etc.).

This is the script:

import urllib2, re, os
streams = dict([(s[0],s[1]) for s in [l.split() for l in open('streams.txt').readlines()] if len(s)==2])

for name, num in streams.items():
 pageurl = 'https://streaming.psu.edu/media/?movieId=%s' % num
 page = urllib2.urlopen(pageurl).read()
 result = re.findall('<param name="QTSRC" value="(.*?\.mp4)"/>',page)
 movieurl = result[0]
 command = '/usr/bin/vlc -Irc %s --sout=file/mp4:/home/joerg/Desktop/plonemovs/%s.mp4 vlc://quit' % (movieurl,name)
 print command
print 'fini'

This is the data file, should be calles 'streams'.txt:
