Description John Hurt 2008-06-10 14:44:30 UTC 
The rtspsrc module doesn't make use of the RTSP Scale header. Header and function is defined in the RTSP RFC 2326 section 12.34.

I propose the following patch to add a new "scale" property to the rtspsrc module in order to allow the use of the Scale header.

Comment 2 Wim Taymans 2008-06-11 09:04:39 UTC 
I would not do it that way, GStreamer uses the seek events to control the playback speed of elements, not properties. I would like to see a patch where a property is added to rtspsrc to control the usage of Scale or Speed when performing a rate adjustment with a seek event.
Comment 3 Wim Taymans 2009-04-15 17:03:48 UTC 
We have the SKIP seek flag now to trigger the scale header.

    rtspsrc: use SKIP flag to use SCALE headers
    
    We can use the SKIP seek flag to instruct the server to send data faster then
    normal but with the same bandwidth.
    Fixes #537609
