1.
   MACHINE=dra7xx-evm bitbake gstreamer1.0-plugins-ducati
   MACHINE=dra7xx-evm bitbake gstreamer1.0-plugins-dsp66
   MACHINE=dra7xx-evm bitbake ipumm-fw
   
2.
   edit conf/local.conf, append test:
   
   IMAGE_INSTALL_append += " gstreamer1.0-plugins-ducati"
   IMAGE_INSTALL_append += " gstreamer1.0-plugins-dsp66"
   IMAGE_INSTALL_append += " ipumm-fw"
   IMAGE_INSTALL_append += " gstreamer1.0-plugins-good"
   
3. 
   MACHINE=dra7xx-evm bitbake arago-base-tisdk-image

test command:

gst-launch-1.0 videotestsrc num-buffers=1000 ! 'video/x-raw,formwat=(string)NV12,width=1920,height=1080,framerage=(fraction)60/2' ! ducatih264enc ! filesink location=test.mp4
