| <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 implement and override the |
| SCHEDULING query. |
| </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. |
