Based on tutorial-3, I have the following pipeline working:
filesrc location=/sdcard/video.mpg ! tsdemux ! h264parse ! avdec_h264 ! 
autovideosink

I would like to decode in hardware. I have added androidmedia but any 
combination of amcviddec-* doesn't work: plugin not found. What would be 
the pipeline to decode in hardware? I'm testing on Android 5.0 and 5.1, 
and on Nexus 5 and Nexus 7 2013.

Also, I have downloaded the runtime 1.4.3 but I get the same PIE error 
so I can't just run gst-inspect-1.0 to see the list of available plugins...
