Gst_App_Sink_Pull_Buffer
Gst_App_Sink_Pull_Buffer. Sample = gst_app_sink_pull_sample (gst_app_sink (elt)); The eos signal can also be used to be informed when the eos state is reached to avoid polling.

Char *pret = new char [map. The normal way of retrieving samples from appsink is by using the gst_app_sink_pull_sample and gst_app_sink_pull_preroll methods. Appsink can be used by linking to the gstappsink.h header file to access the methods or by using the appsink action signals and properties.
Gst_App_Sink_Pull_Buffer Gstbuffer * Gst_App_Sink_Pull_Buffer (Gstappsink *Appsink);
I think the reason why the issue happens is because the appsink couldn’t keep up the the source element due to the delay introduced (i.e., wait for x amount of time before calling function b), which is why we see v4l2src. Sample = gst_app_sink_pull_sample (gst_app_sink (elt)); Char* pullimage (int* outlen, gstelement* sink) { // will block until sample is ready.

You can check for the eos state with the eos property or with the is_eos method. But still memory leak occurs. These methods block until a sample becomes available in the sink or when the sink is shut down or reaches eos.

Unlike most gstreamer elements, appsink provides external api functions. In our case sample is encoded picture. Gstsample* sample = gst_app_sink_pull_sample (gst_app_sink (appsink));
