Ok, thanks.

I tried: avenc_mpeg4, avenc_msmpeg4 and avenc_msmpeg4v2.
I generated test videos with no sound channel to see if I could have 
them to play but they don't work.

Here's one of the test videos I used:
gst-launch-1.0 videotestsrc num-buffers=200 \
	! 'video/x-raw,framerate=(fraction)20/1,width=320,height=240' \
	! videoflip method=clockwise \
	! avenc_mpeg4 bitrate=384000 \
	! queue \
	! avimux name=mux \
	! progressreport \
	! filesink location="test-1-avenc_mpeg4.avi"

I've also tried forcing the mpeg4 profile to simple and advanced-simple, 
but the Meizu device still doesn't play the produced videos. In fact, 
the specs say it only plays XviD, so unless it's possible to somehow 
produce XviD using avenc_mpeg4, I think I'm stuck...
