Log video not playing

Video playback on Nexus 7 2013 Android 4.4.3 doesn't work if zero-copy (direct
frame passing from decoder to GPU) is used. No video is displayed.

Also, video is played if frame copy occurs between decoder and GPU.

The exact same problem occurs on two TCL Alcatel OneTouch devices (phone and
Hero8 tablet), both running 4.4.2.

The same app, video, gstreamer-1.7.90 are working on Android 5.0 and 6.0.1.

For information, Android 4.x still represents 35% of the installed park of
Android worldwide.

Attached debug log *:5 on the Alcatel phone.
