<a name="gst-plugins-good-plugins-splitmuxsink.description"></a><h2>Description</h2>
<p>This element wraps a muxer and a sink, and starts a new file when the mux
contents are about to cross a threshold of maximum size of maximum time,
splitting at video keyframe boundaries. Exactly one input video stream
can be muxed, with as many accompanying audio and subtitle streams as
desired.</p>
<p>By default, it uses mp4mux and filesink, but they can be changed via
the 'muxer' and 'sink' properties.</p>
<p>The minimum file size is 1 GOP, however - so limits may be overrun if the
distance between any 2 keyframes is larger than the limits.</p>
<p>If a video stream is available, the splitting process is driven by the video
stream contents, and the video stream must contain closed GOPs for the output
file parts to be played individually correctly. In the absence of a video
stream, the first available stream is used as reference for synchronization.</p>
