[gst-devel] rtspsrc plugin: udpsrc Internal data flow error

[Ting Wang]

Hello,

I'm using rtspsrc, the command:

/mnt/Temp/felix_tmp/output # ../bin/gst-launch rtspsrc location=rtsp://
10.38.38.150/sample_100kbit.mp4 ! fakesink

works OK, and my streaming server is up and in good condition, but when
issuing the command:

/mnt/Temp/felix_tmp/output # ../bin/gst-launch rtspsrc location=rtsp://
10.38.38.150/sample_100kbit.mp4 ! gstrtpjitterbuffer ! rtph264depay !
h264dec ! overlay2sink

I got the following error message:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /pipeline0/rtspsrc0/udpsrc2: Internal data flow error.
Additional debug info:
gstbasesrc.c(2165): gst_base_src_loop (): /pipeline0/rtspsrc0/udpsrc2:
streaming task paused, reason not-linked (-1)
Execution ended after 216414462 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
overlay2 unmap error!
FREEING pipeline ...

What could have caused "Internal data flow error"?  Would someone please
give me some advice? Thank you very much :)

Best regards

Felix
