Adding mp3 support to gstreamer

Adding mp3 support to gstreamer

[Chris Tapp]

I'm trying to add mp3 support to gstreamer.

I've got a task that RDEPENDS on gst-meta-audio. The image produced  
includes gstreamer, as expected.

However, there is no mp3 decoder included. I've tried setting:

COMMERCIAL_AUDIO_PLUGINS = "gst-plugins-ugly-mad", but there was still  
no mp3 support.

I then tried adding an RDEPENDS on gst-ffmpeg. gst-inspect -b showed  
this as 'blacklisted'.

So, I then tried gst-fluendo-mp3, but I get a "nothing provides" error  
at build time.

What do I need to do to get mp3 decoding added to the image?

what does COMMERCIAL_LICENSE has in it ?
You might want to see that package is part of this variable or not

bitbake -e reports:

COMMERCIAL_LICENSE="lame gst-fluendo-mp3 libmad mpeg2dec ffmpeg qmmp"

Right, I'm struggling to find documentation further than what's in the
code[1] and bugzilla[2] (there's probably stuff in the mail archives
too) but, COMMERCIAL_LICENSE is a blacklist - so you have to remove
items from that list to acknowledge that there are likely commercial
implications of using those recipes.

Furthermore, there are white lists of permitted commercially licensed
packages, to which you need to add the output of COMMERCIAL_LICENSE
recipes that you want to include in images (by way of appending them to
default installation targets in various recipes).

COMMERCIAL_AUDIO_PLUGINS, COMMERCIAL_VIDEO_PLUGINS, and COMMERCIAL_QT

Hope this helps,

Joshua

It does. Thanks.

However, I'm now even more confused ;-)

I've got it working by using the gstreamer recipe from 5.0.1 (I'm  
building under 4.0.1). However, bitbake -e still reports as above and  
I can't see ffmpeg in any context other than

RECIPE_STATUS_pn-gst-ffmpeg="red".

Still, it's working :-)
