| <p>EncodeBin provides a bin for encoding/muxing various streams according to |
| a specified <a href="../html/gst-plugins-base-libs-encoding-profile.html#GstEncodingProfile-struct"><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-1.2.16.9.4"></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="../html/gst-plugins-base-libs-encoding-profile.html#GstEncodingProfile-struct"><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="../html/gst-plugins-base-libs-encoding-profile.html#GstEncodingContainerProfile-struct"><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="../html/gst-plugins-base-libs-encoding-profile.html#GstEncodingAudioProfile-struct"><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="../html/gst-plugins-base-libs-encoding-profile.html#GstEncodingVideoProfile-struct"><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-1.0GstElement.html#GstElement-struct"><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-1.0GstMessage.html#GstMessage-struct"><span class="type">GstMessage</span></a> will be posted on the |
| <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstBus.html#GstBus-struct"><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. |
