 Replying to [comment:32 hackeron]:
 > as indeed the issue is seems to be with that camera's specific web
 server. If I put the file on my own nginx server, I am able to open
 without issues.

 It looks like Mobotix provides a MIME boundary enclosed in quotes -
 http://developer.mobotix.com/docs/mxpeg_frame.html. Uncommon, but valid
 according to RFC 2046. Other people had ran into this before -
 https://code.google.com/archive/p/aforge/issues/157

 Having a full packet capture (including HTTP request/response) will help
 in both confirming this, fixing and verifying the fix. Please provide a
 packet capture (refer to http://www.howtogeek.com/104278/how-to-use-
 wireshark-to-capture-filter-and-inspect-packets/, if unfamiliar with
 Wireshark).
