Hi There, I am trying to download some video with python but have run aground on the rocky shores of pseudostreaming. Fingers crossed someone else here has some experience with this! Here's what I've done so far...
The initial link is foo.asx so I download that with... handle = urllib2.urlopen( 'http://www.example.com/foo.asx' ) mime_type = url_handle.info().getheader("Content-Type","") data = urllib2.read() It comes back with mime type of 'video/x-ms-asf' and the content... 'ASF http://www.example.com/foo-100.wmv' I then used the same code again to grab the URL (ditching the 'ASF ' bit) and this time it comes back with a mime type of 'video/x-ms-wvx' and two URLs... Ref1=http://www.example.com/foo-100.wmv?MSWMExt=.asf Ref2=http://192.168.0.1/foo-100.wmv?MSWMExt=.asf The latter is no use as it's on a private LAN and the second is the same URL as last time, just with a different mime type and naturally it returns the same thing if I use Urllib2 open and read to fetch it with or without the '?MSWMExt=.asf' part. So... I fired up wireshark and spotted these lines coming back in the headers: Server: Cougar/9.01.01.3862 Supported: com.microsoft.wm.srvppair, com.microsoft.wm.sswitch, com.microsoft.wm.predstrm, com.microsoft.wm.fastcache, com.microsoft.wm.startupprofile Euw... I suspected for a second that meant I have to connect with a MS media player or something but the same URL works fine when I paste it into Firefox and the video starts pseudostreaming away so... How can I get their server to give me the video data? Do I need to ask for the file with some other protocol? RTSP? or change my user_agent string and pretend to be Windows Media Player?? Do I need another module as opposed to urllib2? and if so which one? I've had a search but drawn a blank. I guess I'll plug on in wireshark and see what some other programs do but I'd appreciate it if anyone can put me out of my misery! Yours stuck, Roger Heathcote. -- http://mail.python.org/mailman/listinfo/python-list
