-/**
- * SECTION:element-lame
- * @see_also: lame, mad, vorbisenc
- *
- * This element encodes raw integer audio into an MPEG-1 layer 3 (MP3) stream.
- * Note that <ulink url="http://en.wikipedia.org/wiki/MP3">MP3</ulink> is not
- * a free format, there are licensing and patent issues to take into
- * consideration. See <ulink url="http://www.vorbis.com/">Ogg/Vorbis</ulink>
- * for a royalty free (and often higher quality) alternative.
- *
- * <refsect2>
- * <title>Note</title>
- * This element is deprecated, use the lame element instead
- * which provides a much simpler interface and results in better MP3 files.
- * </refsect2>
- *
- * <refsect2>
- * <title>Output sample rate</title>
- * If no fixed output sample rate is negotiated on the element's src pad,
- * the element will choose an optimal sample rate to resample to internally.
- * For example, a 16-bit 44.1 KHz mono audio stream encoded at 48 kbit will
- * get resampled to 32 KHz. Use filter caps on the src pad to force a
- * particular sample rate.
- * </refsect2>
- * <refsect2>
- * <title>Writing metadata (tags)</title>
- * Whilst the lame encoder element does claim to implement the GstTagSetter
- * interface, it does so only for backwards compatibility reasons. Tag writing
- * has been removed from lame. Use external elements like id3v2mux or apev2mux
- * to add tags to your MP3 streams. The same goes for XING headers: use the
- * xingmux element to add XING headers to your VBR mp3 file.
- * </refsect2>
- * <refsect2>
- * <title>Example pipelines</title>
