GNOME Bugzilla – Bug 573173
Added Quicktime HTTP tunneling to the RTSP src element
Last modified: 2009-04-02 20:39:06 UTC
I have added functionality to the RTSP src element to tunnel RTSP and RTP through HTTP as defined by Quicktime. (See the following link for details of how this tunneling works: http://developer.apple.com/documentation/QuickTime/QTSS/Concepts/chapter_2_section_14.html) This functionality is implemented in both gst-plugins-good and in gst-plugins-base. I had to make changes in the gstrtspconnection API to make this work. Since this is a public API I have tried to make it as backward compatible as possible, and in my tests I have managed to use an 'old' rtspsrc element with the new libgstrtsp.so library. There are two ways to use HTTP tunneling with the RTSP src element. 1) Use an HTTP URL in the location property, i.e. location=http://someserver/... 2) Use an ordinary RTSP URL and set the protocols property to 8 I have also added functionality in the RTSP source element to use an HTTP proxy when tunneling over HTTP. The proxy usages is enabled with the 'http-proxy' property. Note, for proxy to work HTTP tunneling must be enabled using an HTTP URL (see 1 above)

GIT contains a similar patch that doesn't touch the message stuff but encapsulates the handling entirely in RTSPConnection, which I think it nicer. No proxy support yet as it's unclear how to do that.
- Added proxy support to the new git HTTP tunneling version. One new property, proxy, on the rtspsrc element. Both gst-plugins-base and gst-plugins-good are updated. Proxy will only work for HTTP tunneling, but could if needed be extended to RTSP proxy (if this exists). Note, no need to use http:// in the url as stated in the beginning of this report, rtsph:// will work. - Fixed bug in gstrtspconnection.c, do_resolve() returned pointer to local (stack) memory.

I don't think the last proxy change works. The GET/PUT request is now: GET /somepath HTTP/1.0 but I think it should be: GET http://hostname/somepath HTTP/1.0 In the base patch from comment #5 I build the GET request with schema and host name and that is accepted by the proxy server I'm using. But the same proxy server refuses the latest version without schema and host. Also, a question about the proxy property in the rtspsrc element. Perhaps it should be able to handle an 'http://' schema prefix in the host name ? i.e. proxy=http://hostname:port The souphttpsrc element for example does not work if you don't prefix the host name with the schema element.
