[Bug 761014] File can't be played with hardware acceleration in Android gstreamer tutorial 5

[GStreamer (GNOME Bugzilla)]

--- Comment #52 from Gregoire <gregoire at gentil.com> ---
1. Hardware decoding was working with Gstreamer 1.5 on Android 5.x (at least
Nexus 7 2013). Only Android 6.x required gstreamer 1.7 for hardware decoding.
You can try the tutorial-5_gstreamer-5 application I uploaded and read the log
to check.

I have reported this current problem in 1.7 at least since last November 2015
on the mailing list. It's not a problem that has been introduced in a very
recent commit.

My purpose of the compilation of tutorial-5 against 1.5 was to show that
hardware decoding has worked WELL with gstreamer. That being said, it was a
very long time ago and way before the new architecture of zero memcpy.

I have never seen a smooth playback on 1.7 compared to what I can see on 1.5.

The position slider is the wrong discussion as I was try to explain in the last
paragraph of comment 50.

In a more complex application I have, which runs Android very busy, I see a lot
of video hiccups with 1.7 while 1.5 is completely smooth. This happens even on
a super fast Nexus 5x. I don't know if your thread explanation is the real
problem. It certainly does make sense with what I see. That would sound more
like an architecture problem than just a bug.
