Log error on the mediatek tablet

I have a Mediatek tablet with API level 19 which fails to decode in hardware a video file with the a playbin3 pipeline.

I attach the log error.

If I use playbin instead, it uses openh264dec and the file plays but the performance is obviously bad as it's decoded in software.

If I use a Nexus 5X android 8.1.0 with the exact same app (based on playbin3), it's working and it decodes correctly in hardware.

Very last, and probably the most important test, I can use VLC on this Mediatek tablet and the file is correctly decoded in hardware.

Comment 2 Gregoire 2018-09-15 02:28:20 UTC 
Once again, the same app is working on Nexus 5X so I don't think that I'm missing anything in the java part.

And vlc works on this tablet with accelerated hardware.

So I really think that the problem is inside the gstreamer library.

Note that I can reproduce the problem with the Android Tutorial 5.
