--- Comment #4 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
The durations are wrong. omxaacdec outputs one output buffer per two input
frames. The duration of each output buffer should be around 90ms, but is only
around 45ms (thus one frame).

It should go into this code here:
http://cgit.freedesktop.org/gstreamer/gst-omx/tree/omx/gstomxaudiodec.c#n527

Where spf should be 1024 (which is not true for all AAC configurations, but
should be true for yours here). Your output buffers seem to contain 2042 (not
2048!) samples, so you should get those warnings there... and it should
calculate nframes to 2.
