I'm trying to get a gstreamer pipeline working using the dsp to encode, so far I think I installed everything I needed, but when I try to run

gst-launch -v videotestsrc num-buffers=2000 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=sample.264

I get an error

"ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not negotiate format
Additional debug info:
gstbasesrc.c(2767): gst_base_src_start (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:"

I was able to get

"gst-launch -v v4l2src num-buffers=1000 ! video/x-raw-yuv,width=320,height=240,framerate=30/1 ! TIVidenc1 codecName=h264enc engineName=codecServer ! rtph264pay pt=96 ! udpsink host= port=10000"

to run, but I get an error when I try to read the udp stream.

Anyone got this to work?
