RTP Streaming using gstreamer fails - gstrtpbin element missing

[ottoblom]

Hi There,

I followed the GStreamer RTP Streaming instructions, but my system doesn't have the gstrtpbin element that is being used. However, I do have udpsrc and various other elements from the plugins-good package. When I rebuild the plugin registry I see a few errors that could be a hint to someone, but unfortunately not to me. Does anyone know what could be the problem ? I'm using the 4.1.0 BSP.

MAX resolution 800x480

Btw, just to clarify - I'm running this on the imx6 board. Also, here is the ./configure output during build. It looks good assuming GstRtpBin is part of the rtpmanager.

I disabled all other plugins (bad, ugly, farsight) and now the gstrtpbin showed up properly. So there has to be some form of conflict

[LeonardoSandova]

Otto, when the conflict occurred, how did you add the elements? Did you use Yocto or LTIB to do the latter?

Leo, we are using LTIB. I'm suspecting the farsight plugins, since they also provide RTP functionality, but have not verified it yet.
