- * Since 0.10.9, any #GstBaseSrc can enable pull based scheduling at any time
- * by overriding #GstBaseSrcClass.check_get_range() so that it returns %TRUE.
- *
* If all the conditions are met for operating in pull mode, #GstBaseSrc is
* automatically seekable in push mode as well. The following conditions must
* be met to make the element seekable in push mode when the format is not
* an EOS message to be posted on the pipeline's bus. Once this EOS message is
* received, it may safely shut down the entire pipeline.
*
- * The old behaviour for controlled shutdown introduced since GStreamer 0.10.3
- * is still available but deprecated as it is dangerous and less flexible.
