Play video of MPEG format without voice output

[charleshuang]

I play video of MPEG format by iMX Player and Gstreamer on i.MX6DQP reference board with Yocto 1.8,

but they can not output audio voice

and the audio format is AC-3.

I used gstreamer command:  

  gst-launch-1.0 playbin uri=file:///home/root/vts2.mpg video-sink="imxv4l2sink"

Are there any advice about the issue?

Thanks

AC-3 is special codec version, you should contact local FAE to sign NDA, then you can get the AC-3 codec .
