Thank You David for the response.
Please note that I am using GStreamer version 1.14.5
I ran valgrind with environment variables as you suggested.
Please find the attached report (streaming_app_valgrind.log)
>From the valgrind report, I could see memory lost at following places:
==12284== by 0x9C73966: gst_rtp_base_payload_sink_event_default (in
/home/xruser/lib/libgstrtp-1.0.so.0.1405.0)
==12284== by 0xBC08E07: gst_vaapipostproc_start (in
/home/xruser/lib/gstreamer-1.0/libgstvaapi.so)
==12284== by 0xBBFF6F5: plugin_init (in
/home/xruser/lib/gstreamer-1.0/libgstvaapi.so)
==12284== by 0xBC03A36: gst_vaapi_plugin_base_ensure_display (in
/home/xruser/lib/gstreamer-1.0/libgstvaapi.so)
==12284== by 0xBC08E07: gst_vaapipostproc_start (in
/home/xruser/lib/gstreamer-1.0/libgstvaapi.so)
Experts, please take a look at the valgrind report and guide me further.
Thanks and Regards,
Saurabh Bora
