I try to output a video with an 5.1 audio track encoded with AAC.

For this I use an Apalis IMX6Q with an Ixora carrier board, and the linux-3.14.28 supplied by Toradex.

I use gstreamer 0.10 with this command :

gst-launch filesrc location=/media/sda1/FILE2_AAC_5-1_TestVideo.mp4 typefind=true ! aiurdemux name=demux demux. ! queue ! vpudec low-latency=true ! imxv4l2sink demux. ! queue ! beepdec ! alsasink device=plughw:2,0

 

But the track of the Surround Right goes on the Front Center, the track of the Front Center goes on the Surrond Left and the track of the Surround Left goes nowhere.

 

For this test I use the following video : https://www2.iis.fraunhofer.de/AAC/multichannel.html

If I play the video with my computer on Ubuntu 14.04 its work well.

 

Anybody have a solution to get the correct output ?
