java - Memory Consumption is always increasing in Humble-Video -

i have been using humble-video in live streaming project convert flv mp4. i've realized java process's(in humble-video codes running) memory usage increasing when looking top command.

after changed demo source code of humble-video , put segmentfile function in infinite loop , memory usage of process again increasing when looking top command. on 2.5gib , has been running 30 mins.

i expect process's memory consumption stay stable somewhere between 40-50mb not keep increasing always.

do have idea that?

i've resolved problem.

the problem garbage collector not clear weakreferences jnimemorymanager not delete native objects. calling system.gc() after every iteration helping not exact solution.

the solution calling delete() @ end of each iteration. objects created may not expect during execution please @ objects created jnimemorymanager.getmgr().dumpmemorylog(); , @ how many objects alive jnimemorymanager.getmgr().getnumpinnedobjects();

the last state of segmentfile function below , memory consumption still stays 80 mib @ end of 15min.
