Hardware decoding on android using GStreamer

[Robert Krakora]

What is the output of "gst-inspect amcviddec-omxgoogleh264decoder"? What is
the output of the pipeline below in the log.txt file?

GST_DEBUG=amcviddec-omxgoogleh264decoder:5 GST_DEBUG_NO_COLOR=TRUE
gst-launch filesrc
location=/storage/sdcard0/Movies/c48000.mp4 ! qtdemux ! queue ! h264parse !
amcviddec-omxgoogleh264decoder ! eglglessink sync=FALSE &>log.txt
