I set the http_proxy environment variable, but still getting the same error. <o:p></o:p> Can you tell me why this error is coming again and again? What mistake did I made?  I check the proxy using Curl, its fine.<o:p></o:p> <o:p> </o:p> Regards,<o:p></o:p> Deb <o:p></o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: Ron McOuat [via GStreamer-devel] [mailto:<a href="http://n4.nabble.com/user/SendEmail.jtp?type=node&node=1578051&i=0" target="_top" rel="nofollow">[hidden email]</a>] Sent: Wednesday, February 24, 2010 11:36 AM To: <st1:PersonName w:st="on">Debojyoti Pal</st1:PersonName> (WT01 - PES-Mobile-Auto-CE Practice) Subject: Re: Playbin unable to play http stream<o:p></o:p> </div> <o:p> </o:p> I added user authentication to souphttpsrc around Nov 2008 when there was no means to provide basic or digest authentication on direct access to a URL and souphttpsrc did not accept the <a href="http://user@password" target="_top" link="external" rel="nofollow">http://user@password</a>  embedded format either and still does not. I had a strong need for this capability in my own work. Looking at the libsoup documentation it looked like it was possible to service error code SOUP_STATUS_PROXY_AUTHENTICATION_REQUIRED in the same callback routine as regular authentication SOUP_STATUS_UNAUTHORIZED both of which are in function gst_soup_http_src_authenticate_cb() so I added properties proxy_id and proxy_pw to the souphttpsrc element properties to source the values for proxy authentication. Unless libsoup reads the environment for these values and could do proxy authentication automatically I know I didn't put the code in to read the environment to pick up the properties from there instead of from the added element properties. In retrospect using the environment is likely a better approach because proxy settings are often a system setting. I also have limited ability to test this since proxy is not part of my environment. I suppose setting up squid is all that is really needed and force a test environment to use the squid setup. My workload has prevented me from testing this further. Maybe the best approach is to file a bug report and if there is someone better skilled at using a proxy environment to find what is wrong with this? I believe libsoup has had a number of issues with proxy over time but think that is not an issue now but don't take my word for it, I was getting this from reading the libsoup discussion area and not actual testing. Going back to the URL in the original request I tried the gst-launch command on a stock Ubuntu 9.10 Karmic system without a need for proxy and the pipeline says it got EOS during preroll and did not display the picture in a video sink which is not surprising since the URL content is only a single JPG image. I would normally associate using gstreamer with processing a sequence of video frames instead of just one image. Not to discourage you from gstreamer but grabbing a single image frame looks more like a file transfer job which libCurl you mention does quite well. I probably just don't know what you want to do with the image content after it is acquired so my comment is probably not valid.
