<a name="gst-plugins-base-plugins-encodebin.description"></a><h2>Description</h2>
<p>EncodeBin provides a bin for encoding/muxing various streams according to
a specified <a href="../gst-plugins-base-libs-1.0/gst-plugins-base-libs-encoding-profile.html#GstEncodingProfile"><span class="type">GstEncodingProfile</span></a>.</p>
<p>Based on the profile that was set (via the <a class="link" href="gst-plugins-base-plugins-encodebin.html#GstEncodeBin--profile" title="The “profile” property"><span class="type">“profile”</span></a> property),
EncodeBin will internally select and configure the required elements
(encoders, muxers, but also audio and video converters) so that you can
provide it raw or pre-encoded streams of data in input and have your
encoded/muxed/converted stream in output.</p>
<div class="refsect2">
<a name="id-1.2.14.9.4"></a><h3>Features</h3>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
Automatic encoder and muxer selection based on elements available on the
system.
</li>
<li class="listitem">
Conversion of raw audio/video streams (scaling, framerate conversion,
colorspace conversion, samplerate conversion) to conform to the profile
output format.
</li>
<li class="listitem">
Variable number of streams. If the presence property for a stream encoding
profile is 0, you can request any number of sink pads for it via the
standard request pad gstreamer API or the <a class="link" href="gst-plugins-base-plugins-encodebin.html#GstEncodeBin-request-pad" title="The “request-pad” signal"><span class="type">“request-pad”</span></a> action
signal.
</li>
<li class="listitem">
Avoid reencoding (passthrough). If the input stream is already encoded and is
compatible with what the <a href="../gst-plugins-base-libs-1.0/gst-plugins-base-libs-encoding-profile.html#GstEncodingProfile"><span class="type">GstEncodingProfile</span></a> expects, then the stream won't
be re-encoded but just passed through downstream to the muxer or the output.
</li>
<li class="listitem">
Mix pre-encoded and raw streams as input. In addition to the passthrough
feature above, you can feed both raw audio/video *AND* already-encoded data
to a pad. <a class="link" href="gst-plugins-base-plugins-encodebin.html#GstEncodeBin"><span class="type">GstEncodeBin</span></a> will take care of passing through the compatible
segments and re-encoding the segments of media that need encoding.
</li>
<li class="listitem">
Standard behaviour is to use a <a href="../gst-plugins-base-libs-1.0/gst-plugins-base-libs-encoding-profile.html#GstEncodingContainerProfile"><span class="type">GstEncodingContainerProfile</span></a> to have both
encoding and muxing performed. But you can also provide a single stream
profile (like <a href="../gst-plugins-base-libs-1.0/gst-plugins-base-libs-encoding-profile.html#GstEncodingAudioProfile"><span class="type">GstEncodingAudioProfile</span></a>) to only have the encoding done and
handle the encoded output yourself.
</li>
<li class="listitem">
Audio imperfection corrections. Incoming audio streams can have non perfect
timestamps (jitter), like the streams coming from ASF files. <a class="link" href="gst-plugins-base-plugins-encodebin.html#GstEncodeBin"><span class="type">GstEncodeBin</span></a>
will automatically fix those imperfections for you. See
<a class="link" href="gst-plugins-base-plugins-encodebin.html#GstEncodeBin--audio-jitter-tolerance" title="The “audio-jitter-tolerance” property"><span class="type">“audio-jitter-tolerance”</span></a> for more details.
</li>
<li class="listitem">
Variable or Constant video framerate. If your <a href="../gst-plugins-base-libs-1.0/gst-plugins-base-libs-encoding-profile.html#GstEncodingVideoProfile"><span class="type">GstEncodingVideoProfile</span></a> has
the variableframerate property deactivated (default), then the incoming
raw video stream will be retimestampped in order to produce a constant
framerate.
</li>
<li class="listitem">
Cross-boundary re-encoding. When feeding compatible pre-encoded streams that
fall on segment boundaries, and for supported formats (right now only H263),
the GOP will be decoded/reencoded when needed to produce an encoded output
that fits exactly within the request GstSegment.
</li>
<li class="listitem">
Missing plugin support. If a <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstElement.html"><span class="type">GstElement</span></a> is missing to encode/mux to the
request profile formats, a missing-plugin <a href="/usr/share/gtk-doc/html/gstreamer-1.0/gstreamer-GstMessage.html#GstMessage"><span class="type">GstMessage</span></a> will be posted on the
<a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstBus.html"><span class="type">GstBus</span></a>, allowing systems that support the missing-plugin system to offer the
user a way to install the missing element.
