高分求助！gstreamer的playbin2问题

小弟的播放器用gstreamer的playbin2当做核心组件，遇到内存无法释放的问题：
描述：
系统内存
播放前 30MB
播放完1曲 30+5*1(MB 大概)
播放完n曲 30+5*n(MB 大概)
播放完最后一曲循环播放，内存稳定在30+5*n（MB），内存不继续增加。问题是：N比较大的时
候，内存就被耗尽...
是不是我的单曲结束时释放操作未做，还是其控制就是如此？望有过相关开发经历的XD给些建议！
贴上部分控制代码：

#include "player_types.h"

这样的话，应该不是gstreamer管道造成的内存泄漏了。
建议你仔细查看下你的playlist链表。
