## Description

The downloadbuffer element provides on-disk buffering and caching of, typically, a network file. temp-template should be set to a value such as /tmp/gstreamer-XXXXXX and the element will allocate a random free filename and buffer the data in the file.

With max-size-bytes and max-size-time you can configure the buffering limits. The downloadbuffer element will try to read-ahead these amounts of data. When the amount of read-ahead data drops below low-percent of the configured max, the element will start emitting BUFFERING messages until high-percent of max is reached again.

The downloadbuffer provides push and pull based scheduling on its source pad and will efficiently seek in the upstream element when needed.

The temp-location property will be used to notify the application of the allocated filename.

When the downloadbuffer has completely downloaded the media, it will post an application message named `"GstCacheDownloadComplete"` with the following information:

* G_TYPE_STRING

`"location"`:

the location of the completely downloaded file.
