27 * SECTION:element-queue2
29 * Data is queued until one of the limits specified by the
30 * #GstQueue2:max-size-buffers, #GstQueue2:max-size-bytes and/or
31 * #GstQueue2:max-size-time properties has been reached. Any attempt to push
32 * more buffers into the queue will block the pushing thread until more space
35 * The queue will create a new thread on the source pad to decouple the
36 * processing on sink and source pad.
38 * You can query how many buffers are queued by reading the
39 * #GstQueue2:current-level-buffers property.
41 * The default queue size limits are 100 buffers, 2MB of data, or
42 * two seconds worth of data, whichever is reached first.
44 * If you set temp-tmpl to a value such as /tmp/gstreamer-XXXXXX, the element
45 * will allocate a random free filename and buffer data in the file.
46 * By using this, it will buffer the entire stream data on the file independently
47 * of the queue size limits, they will only be used for buffering statistics.
49 * Since 0.10.24, setting the temp-location property with a filename is deprecated
50 * because it's impossible to securely open a temporary file in this way. The
51 * property will still be used to notify the application of the allocated
