+Compiling AMRNB:
+================
+
+To compile the amrnb plugin, you need the opencore-amrnb development package.
+If your distribution does not provide this package, you can download the
+source code from "http://sourceforge.net/projects/opencore-amr".

+ * <para>
+ * cdiocddasrc reads and extracts raw audio from Audio CDs. It can operate
+ * in one of two modes:
+ * <itemizedlist>
+ * <listitem><para>
+ * treat each track as a separate stream, counting time from the start
+ * of the track to the end of the track and posting EOS at the end of
+ * a track, or
+ * </para></listitem>
+ * <listitem><para>
+ * treat the entire disc as one stream, counting time from the start of
+ * the first track to the end of the last track, posting EOS only at
+ * the end of the last track.
+ * </para></listitem>
+ * </itemizedlist>
+ * </para>
+ * <para>
+ * With a recent-enough version of libcdio, the element will extract
+ * CD-TEXT if this is supported by the CD-drive and CD-TEXT information
+ * is available on the CD. The information will be posted on the bus in
+ * form of a tag message.
+ * </para>
+ * <para>
+ * When opened, the element will also calculate a CDDB disc ID and a
+ * MusicBrainz disc ID, which applications can use to query online
+ * databases for artist/title information. These disc IDs will also be
+ * posted on the bus as part of the tag messages.
+ * </para>
+ * <para>
+ * cdiocddasrc supports the GstUriHandler interface, so applications can use
+ * playbin with cdda://<track-number> URIs for playback (they will have
+ * to connect to playbin's notify::source signal and set the device on the
+ * cd source in the notify callback if they want to set the device property).
+ * Applications should use seeks in "track" format to switch between different
+ * tracks of the same CD (passing a new cdda:// URI to playbin involves opening
+ * and closing the CD device, which is much slower).
+ * </para>
+ * <title>Example launch line</title>
+ * <para>
+ * <programlisting>
+ * gst-launch cdiocddasrc track=5 device=/dev/cdrom ! audioconvert ! vorbisenc ! oggmux ! filesink location=track5.ogg
+ * </programlisting>
+ * This pipeline extracts track 5 of the audio CD and encodes it into an
+ * Ogg/Vorbis file.

+ * SECTION:element-lamemp3enc
+ * @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>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.

+/**
+ * SECTION:element-x264enc
+ * @see_also: faac
+ *
+ * This element encodes raw video into H264 compressed data,
+ * also otherwise known as MPEG-4 AVC (Advanced Video Codec).
+ *
+ * The #GstX264Enc:pass property controls the type of encoding. In case of Constant
+ * Bitrate Encoding (actually ABR), the #GstX264Enc:bitrate will determine the quality
+ * of the encoding. This will similarly be the case if this target bitrate
+ * is to obtained in multiple (2 or 3) pass encoding.
+ * Alternatively, one may choose to perform Constant Quantizer or Quality encoding,
+ * in which case the #GstX264Enc:quantizer property controls much of the outcome, in that case #GstX264Enc:bitrate is the maximum bitrate.
+ *
+ * The H264 profile that is eventually used depends on a few settings.
+ * If #GstX264Enc:dct8x8 is enabled, then High profile is used.
+ * Otherwise, if #GstX264Enc:cabac entropy coding is enabled or #GstX264Enc:bframes
+ * are allowed, then Main Profile is in effect, and otherwise Baseline profile
+ * applies. The main profile is imposed by default,
+ * which is fine for most software players and settings,
+ * but in some cases (e.g. hardware platforms) a more restricted profile/level
+ * may be necessary. The recommended way to set a profile is to set it in the
+ * downstream caps.
+ *
+ * If a preset/tuning are specified then these will define the default values and
+ * the property defaults will be ignored. After this the option-string property is
+ * applied, followed by the user-set properties, fast first pass restrictions and
+ * finally the profile restrictions.
+ *
+ * <note>Some settings, including the default settings, may lead to quite
+ * some latency (i.e. frame buffering) in the encoder. This may cause problems
+ * with pipeline stalling in non-trivial pipelines, because the encoder latency
+ * is often considerably higher than the default size of a simple queue
+ * element. Such problems are caused by one of the queues in the other
+ * non-x264enc streams/branches filling up and blocking upstream. They can
+ * be fixed by relaxing the default time/size/buffer limits on the queue
+ * elements in the non-x264 branches, or using a (single) multiqueue element
+ * for all branches. Also see the last example below.
+ * </note>
+ *
+ * <refsect2>
+ * <title>Example pipeline</title>
+ * |[
+ * gst-launch -v videotestsrc num-buffers=1000 ! x264enc qp-min=18 ! \
+ * avimux ! filesink location=videotestsrc.avi
+ * ]| This example pipeline will encode a test video source to H264 muxed in an
+ * AVI container, while ensuring a sane minimum quantization factor to avoid
+ * some (excessive) waste.
+ * |[
+ * gst-launch -v videotestsrc num-buffers=1000 ! x264enc pass=quant ! \
+ * matroskamux ! filesink location=videotestsrc.avi
+ * ]| This example pipeline will encode a test video source to H264 using fixed
+ * quantization, and muxes it in a Matroska container.
+ * |[
+ * gst-launch -v videotestsrc num-buffers=1000 ! x264enc pass=5 quantizer=25 speed-preset=6 ! video/x-h264, profile=baseline ! \
+ * qtmux ! filesink location=videotestsrc.mov
+ * ]| This example pipeline will encode a test video source to H264 using
+ * constant quality at around Q25 using the 'medium' speed/quality preset and
+ * restricting the options used so that the output is H.264 Baseline Profile
+ * compliant and finally multiplexing the output in Quicktime mov format.
+ * |[
+ * gst-launch -v videotestsrc num-buffers=1000 ! tee name=t ! queue ! xvimagesink \
+ * t. ! queue ! x264enc rc-lookahead=5 ! fakesink
+ * ]| This example pipeline will encode a test video source to H264 while
+ * displaying the input material at the same time. As mentioned above,
+ * specific settings are needed in this case to avoid pipeline stalling.
+ * Depending on goals and context, other approaches are possible, e.g.
+ * tune=zerolatency might be configured, or queue sizes increased.
