-/*
- * an example application of using appsrc in streaming push mode. We simply push
- * buffers into appsrc. The size of the buffers we push can be any size we
- * choose.
- *
- * This example is very close to how one would deal with a streaming webserver
- * that does not support range requests or does not report the total file size.
- *
- * Some optimisations are done so that we don't push too much data. We connect
- * to the need-data and enough-data signals to start/stop sending buffers.
- *
- * Appsrc in streaming mode (the default) does not support seeking so we don't
- * have to handle any seek callbacks.
- *
- * Some formats are able to estimate the duration of the media file based on the
- * file length (mp3, mpeg,..), others report an unknown length (ogg,..).
