Hello everyone,
I need to restart the pipeline constantly. I find that the memory will rise (memory leak?), I have tried many versions of gstreamer and deepstream, including Gstreamer1.14.5, 1.18.2, 1.20.3, 1.20.4 DeepStream 4.0, 5.0, and 5.1. The following is a demo
test.c
need to change the location of rtspsrc
#include <locale.h>
#include <glib.h>
#include <gst/gst.h>
#include <glib-unix.h>
#include <stdio.h>
#include <stdbool.h>
static gboolean
quit_loop (gpointer data)
{
g_print("quit \n");
GMainLoop *loop = (GMainLoop*)data;
g_main_loop_quit(loop);
return false;
}
int main(int argc, char *argv[]){
/* Initialize GStreamer */
gst_init (&argc, &argv);
while (1){
GMainLoop *mainloop = g_main_loop_new(NULL, FALSE);
GstElement* pipeline =
gst_parse_launch
("rtspsrc location=rtsp://admin:passwd@ip ! parsebin ! h264parse ! avdec_h264 ! fakesink ",
NULL);
g_print("playing\n");
gst_element_set_state (pipeline, GST_STATE_PLAYING);
g_timeout_add_seconds(30,(GSourceFunc)quit_loop,mainloop);
g_print("run\n");
g_main_loop_run(mainloop);
gst_element_set_state(pipeline,GST_STATE_NULL);
g_print("unref \n");
gst_object_unref(pipeline);
g_main_loop_unref(mainloop);
}
return 0;
}
MakeFile
CC := gcc
LIBS := $(shell pkg-config --libs --cflags gstreamer-1.0 )
test: test.c
"$(CC)" $^ $(LIBS) -o $@
There are two problems in the above code.
- After the pipe is closed( code : “gst_element_set_state(pipeline,GST_STATE_NULL)”), the memory is not reduced.
- Constantly re creating and closing the pipeline will cause the memory to increase all the time.According to different element, the number of Memory can vary from <10M to >100M over a period of time.
This problem can be reproduced using any element and any version of Gstreamer/DeepStream，This problem occurs even when using Rust.(Python and java have GC, which has no reference significance.)This problem is 100% recurrent
Same question link：
This problem will make it impossible for me to restart a pipeline in the program for many times, and I can only restart the program every time.
Is my method of use wrong?
Look forward to your reply, thank you
