ffmedia拉流两路1080P视频时，内存有溢出，第一层增长264KB，会不断增长，大概运行二十多分钟就会报下面的错误，请问是什么原因导致的

ffmedia 是啥？看log是内存泄漏了，退出时有东西没销毁干净

[zackcsao]

python代码调用的(https://github.com/Firefly-rk-linux-utils/ffmedia_release)，这个多媒体库，看不出来python在哪一层有没清理干净的，官方建议用什么多媒体库来实现摄像头的拉流，解码，AI处理后，编码推送呢？Gstreamer使用时，无法使用成功DMA的内存零拷贝，官方有没有相关的建议核资料

[HermanChen]

linux 上用 gstreamer 会好一些，官方的 linux sdk 带的就是 gstreamer

[HermanChen]

gstreamer 上有零拷贝的做法

[zackcsao]

这个有参考例程吗？

[HermanChen]

建议使用 RK 的 rockit 来实现这些个功能会比较好
