Re: Audio is working with *.wav format files with USB headset on Raspberry Pi3: FF-6.0.2

Hi George,

               I am trying to add the gstreamer1.0-plugins-ugly to my AGL image by adding the following lines in local.conf file.

IMAGE_INSTALL_append = " gstreamer1.0-plugins-good gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly"
LICENSE_FLAGS_WHITELIST_append = " commercial_gstreamer1.0-plugins-ugly "

LICENSE_FLAGS_WHITELIST_append = " commercial_mpg123 "

With the above changes, compilation failed with the below errors:

I am looking at it.

Hi Madhu,

There is no restriction on the MP3 format, however, the MP3 GStreamer plugins
have been classified as unrestricted in version 1.14 of GStreamer (by moving
them to the -plugins-good module of GStreamer), while the version of yocto used
by AGL still ships GStreamer 1.12 and doesn't build by default the -plugins-ugly
module, where the MP3 plugins used to be.

You can probably enable them by including the gstreamer1.0-plugins-ugly recipe
manually in your image.

Regards,
George
