<p>
This class is mostly useful for elements that cannot do
random access, or at least very slowly. The source usually
prefers to push out a fixed size buffer.
</p>
<p>
Subclasses usually operate in a format that is different from the
default GST_FORMAT_BYTES format of <a class="link" href="GstBaseSrc.html" title="GstBaseSrc"><span class="type">GstBaseSrc</span></a>.
</p>
<p>
Classes extending this base class will usually be scheduled
in a push based mode. If the peer accepts to operate without
offsets and within the limits of the allowed block size, this
class can operate in getrange based mode automatically. To make
this possible, the subclass should override the ::check_get_range
method.
</p>
<p>
The subclass should extend the methods from the baseclass in
addition to the ::create method.
</p>
<p>
Seeking, flushing, scheduling and sync is all handled by this
base class.
