[Gstreamer-openmax] Re： Re: Re: Does gstopenmax have plan to update omxil to Bellagio 0.9. x?=

[Giulio URLINI]

Hi,
	I'm Giulio Urlini and I'm responsible for the Bellagio development. In
my opinion this is not a problem of the relation between gstreamer and
openmax but a decoding error inside the openmax audio decoder.
The error in this case seems to be related to faac version that does not
match. Which version of ffmpeg are you using?
Did you try to run the openmax stand alone demo, in
tests/components/audio/omxaudiodectest?
