* STREAM_LOCK held.
* @convert: Optional.
* Convert between formats.
- * @find_frame: Optional.
- * Finds a frame. Gets a position passed and should return
- * TRUE and the offset in bytes where this position is.
- * Will only be called in pull mode and the subclass can pull
- * whatever it wants from upstream. If not implemented,
- * the base class will implement it by calling
- * @check_valid_frame and @parse_frame to find the wanted
- * frame and build a seek table.
* @event: Optional.
* Event handler on the sink pad. This function should return
* TRUE if the event was handled and can be dropped.
* Event handler on the source pad. Should return TRUE
* if the event was handled and can be dropped.
*
- * @get_frame_overhead: Finds the metadata overhead for the given frame. This
- * is used to enable more accurate bitrate computations.
- * If NULL, the per-frame overhead is assumed to be 0. If
- * this returns -1, it is assumed that this frame should
- * be skipped in bitrate calculation.
- *
- * @pre_push_buffer: Optional.
+ * @pre_push_frame: Optional.
* Called just prior to pushing a frame (after any pending
* events have been sent) to give subclass a chance to perform
* additional actions at this time (e.g. tag sending) or to
