Hi Carlos/All
I want to understand why LICENSE_FLAGS = "commercial" was added to
meta-multimedia/recipes-multimedia/mpg123/mpg123_1.15.3.bb
in initial commit and has been carried over upgrades ever since
The license seems to be LGPL 2.0 and is explained in greater detail here
http://mpg123.org/cgi-bin/scm/mpg123/trunk/doc/ROAD_TO_LGPL?revision=2607
So what portions of it are having different terms for commercial distribution ?
Thanks
-Khem

It's because MPEG audio is subject to royalties. This is also the reason
why gst-plugins-ugly and gstreamer1.0-plugins-ugly have this flag.

But does gst-plugins-ugly provide own codecs? It's mostly a collection of
external plugins, so it shouldn't itself be marked as "commercial":

But the whole point of gst-plugins-ugly is to be a collection of tested
high-quality plugins for formats and standards which are subject to
royalties. Tested quality plugins without the royalty go to -good.

In what way where the component is lgpl I would like to understand

*mpg123* is LGPL. But mpg123 is an implementation of an MPEG 1 audio
layer 1/2/3 and MPEG 2 audio. MPEG-1 layer 3 is what everybody calls
mp3. (mp1 and mp2 are pretty much dead by now.) mp3 itself contains
patents, and these are subject to royalties. Technicolor (formerly
Thomson) does enforce these royalties. See
http://mp3licensing.com/royalty/software.html for their price model.
MPEG-2 is controlled by the MPEG LA.
Note that these royalties cover the audio technology itself (say, mp3),
*not* the implementations. Implementations themselves can be subject to
any license, it's up to the authors of the implementations. But if you
actually want to use these implementations in a commercial product,
you'll have to pay the royalty fees.
This is part of the reason why Ogg Vorbis (and Opus) exist. They are an
alternative that doesn't require such fees. Therefore, the Vorbis
decoder isn't in gst-plugins-ugly, but in gst-plugins-good.
