Hi all, As I’m a begginer on gstreamer, I have faced some problem in my application. I made a play sound function using gstreamer 1.0 and it worked fine. But problem is, after finishing a sound play, there is some memory leak. Could you please check if my code there is something wrong? FYI, gst_init() was called in main function at startup stage. play_sound was called from time to time as needed with differenent source file.
