Missing Audio CODEC

[PaulDeMetrotion]

I am trying to play an AVI file using gst-launch-0.1. The video works great but there is no audio. How do I build all of the provided CODECs with Yocto? I am not sure if I am getting all of the plug-ins. During the LTIB days, I copied the CODEC binaries straight to the kernel, but I cannot find the same content.

I am using Yocto to build a 3.14.28 version kernel for a custom device. I am using the fsl-image-gui recipe. I have also tired the fsl-image-multimedia-full recipe and got the same error message.

Hi

AC3 support is not available.

You need to signed licence agreement for the AC3 support.

Thanks

Thanks, I did find the following in a README:

Restricted Codecs

-----------------

Some codecs (Microsoft, AC3 and AACP) have recipes in this layer but binaries are not provided in

the Yocto Project fetch system.

These codecs have contractual restrictions that require separate distribution.

Any idea how I get this resolved?

Hi Paul

ac3 codec is described in attached Release Notes Table 7. Controlled access packages :

"Contact marketing representative to get access to the following controlled packages."

Best regards

igor
