the h/w accelerated decoding in the video you mentioned was not on
IFC6540, but on IFC6410. Which uses a different SoC.
As of now, there is no support for h/w video decoder on the APQ8084
SoC which you have on the IFC6540. This might come in the future,
though..
Also, on IFC6410 the video decoder acceleration was provided through a
Gstreamer plugin (which in turns uses a custom char driver in the
kernel), and there has been so far no integration into ffmpeg, only
Gstreamer.

Now on the rendering side of things (rendering of video frames) if you
application uses GL/GLES, then it should work fine through the
GPU/freedreno.
