I’m able to send rtp streams across the network using nvv4l2h265enc and receive rtp streams in gstreamer pipeline for c program code; To adapt to the poor situation of the network,the stream resolution will change:[1280x960,640x480,480x360]; but after change resolution test 488 times, nvv4l2h265e…

Hi, Do you observe the issue on TX2 developer kit? We have set up r32.5.0/TX2 developer kit and run the python sample. Don’t hit crash and memory increase.

Hi, Do you re-initialize the gstreamer pipeline when resolution changes? By default it does not support runtime resolution change in nvv4l2h265enc. When resolution changes, please terminate the original pipeline and re-initialize a new one.

yes,we release pipeline source and use new resolution to start pipeline,repeated; just like this topic Camera liveview cannot show up again after repeated open/close the liveview for several times - #23 by DaneLLL but on my test,gst_element_send_event will be locked!!! [a]

And in my another test,delete send eos,it repeated 14276 times and crashed,locked on gst_pad_stop_task steps: 1 gst_element_set_state(rts->pipeline, GST_STATE_NULL); 2 gst_object_unref(rts->pipeline); 3 g_usleep(1000000); 4 reinitialize pipeline [1626075245]

Hi, We would need your help to share a test sample based on either Camera liveview cannot show up again after repeated open/close the liveview for several times - #19 by DaneLLL or Camera liveview cannot show up again after repeated open/close the liveview for several times - #23 by DaneLLL So …

Hi, The fix for the topic is in nvvidconv plugin and r32.5 contains the fix. Fir this issue, please try Memory Leak (Alloc/free mismatch) in Tegra multimedia API (encoder) - #6 by DaneLLL

ok,i will try that topic fix so file! what about the lowlevellock issue?

i test ,it also occure memory leak ! i test on 3 tx2;one repeat restart gstreamer pipeline 76449 times,memory from 1% to 37.8%;another repeat restart gstreamer pipeline 81399 times,memory from 1% to 25.4%;the third repeat restart gstreamer pipeline 55893 times,memory from 1% to 28.4%; the memory l…

Hi, Sorry I did not put correct link in the comment I have correct it and please give it a try.

on my test,it also some memory leak, repeated 500time,memory will add 3%[top cmd],just like this top[Using nvv4l2h264enc encoder memory increases when releasing pipeline and setting up a new one - #19 by DaneLLL], how about the 32.5 version ?
