<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a question regarding gstreamer when an element runs slowly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have 4 uridecodebins as sources (reading rtsp streams) and I link the pads to streammux, then I do
<o:p></o:p></p>
<p class="MsoNormal"><span style="background:#DEDEDE">gst_link_many(nvstreammux, nvvidconv, queue, yolo_plugin, appsink, NULL);</span><br>
<br>
<span style="background:#DEDEDE">To simulate a slow plugin, I sleep for 5 seconds in yolo_plugin whenever it receives a frame upstream. If I do not sleep, yolo_plugin will take 300ms to run. Despite having a queue, it does not give me the latest frame, but
it gives me the next frame from the camera stream. </span><br>
<br>
<span style="background:#DEDEDE">Can anyone help me to understand why is there no dropping of frames despite having a queue? I also noticed that rtspsrc in uridecodebin is only running once every 5seconds from the debug log, this seems very weird to me.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="background:#DEDEDE"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="background:#DEDEDE">My desired outcome is that the uridecodebin will constantly decode the rtsp stream, and the queue will just drop the frames when yolo_plugin is running too slowly, but this is not the case. Can anyone help?<o:p></o:p></span></p>
