The utilty doesn't seem to work for some of the DASH-IF test assets:

python dashproxy.py "https://dash.akamaized.net/dash264/TestCasesHD/MultiPeriod_OnDemand/TwoPeriods/TwoPeriod_OnDemand.mpd" -o .

I had the same kind of errors when tying to download a live streaming content:

Traceback (most recent call last): File "dashproxy.py", line 289, in main() File "dashproxy.py", line 286, in main run(args) File "dashproxy.py", line 275, in run return proxy.run() File "dashproxy.py", line 115, in run self.refresh_mpd() File "dashproxy.py", line 128, in refresh_mpd mpd = xml.etree.ElementTree.fromstring(r.text) File "/usr/lib/python2.7/xml/etree/ElementTree.py", line 1311, in XML parser.feed(text) File "/usr/lib/python2.7/xml/etree/ElementTree.py", line 1657, in feed self._parser.Parse(data, 0) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe3' in position 116169: ordinal not in range(128)

How could we fix this issue?
