Hi, Most of the time, using "download helper" plugin for firefox I can get the "playable" uri. (not only well known web site like youtube etc...) But I tried on the web site <a href="http://www.rtl.fr">www.rtl.fr</a>, I selected randomly a video and "download helper" plugin said: <a href="http://v.kewego.com/v/5/0992/37PPGYC6">http://v.kewego.com/v/5/0992/37PPGYC6</a>.mp4?key%3D20d855c7a7fd99fc Note the http://....mp4? key%... So it seems that key%... is used for authentification or something else. Then I tried to play to play it with gstreamer: -- gst-launch-0.10 playbin uri="<a href="http://v.kewego.com/v/5/0992/37PPGYC6.mp4?key%3D20d855c7a7fd99fc">http://v.kewego.com/v/5/0992/37PPGYC6.mp4?key%3D20d855c7a7fd99fc</a>" but I got the same result as if I do not put the key stuff, I mean I got the same result as -- gst-launch-0.10 playbin uri="<a href="http://v.kewego.com/v/5/0992/37PPGYC6.mp4">http://v.kewego.com/v/5/0992/37PPGYC6.mp4</a>" result ->403 Forbidden Sothe video is not playable with the pipeline. But it's still working with: firefox <a href="http://v.kewego.com/v/5/0992/37PPGYC6.mp4?key%3D20d855c7a7fd99fc">http://v.kewego.com/v/5/0992/37PPGYC6.mp4?key%3D20d855c7a7fd99fc</a> Is it possible to configure souphttpsrc for auth, maybe user-pw property ? cookies ? Well, does anyone already encounter this kind of uri ? Sincerely Julien
