Such thing would would be great way to debug. Is there any environment variable which I can use to configure this ring buffer logs?</div><div class=""><br class=""></div><div class="">I mean I can set this ringbuffer up with gst_debug_remove_log_function(NULL) and gst_debug_add_ring_buffer_logger but we were not able to detect the problem from within the application so far. We only notice that the CPU load drops and the stream is stopped and as I guess I should call the gst_debug_ring_buffer_logger_get_logs from within the application and I dont really have a trigger point.</div><div class=""><br class=""></div><div class="">I tried to add a callback on the pipeline to print status messages / state changes with:</div><div class=""><br class=""></div><div class=""><div style="color: rgb(54, 54, 54); background-color: rgb(255, 255, 255); font-family: Menlo, Monaco, "Courier New", monospace; font-weight: 800; font-size: 10px; line-height: 15px; white-space: pre;" class=""><br class=""><div class=""> bus = <span style="color: rgb(99, 99, 36);" class="">gst_element_get_bus</span> (pipeline);</div><div class=""> <span style="color: rgb(99, 99, 36);" class="">gst_bus_add_signal_watch</span> (bus);</div><div class=""> <span style="color: rgb(99, 99, 36);" class="">g_signal_connect</span> (bus, <span style="color: rgb(162, 86, 55);" class="">"message"</span>, <span style="color: rgb(99, 99, 36);" class="">G_CALLBACK</span> (cb_message), pipeline);</div><br class=""></div></div><div class=""><div><br class=""></div><div>and then:</div><div><br class=""></div><div><div style="color: rgb(54, 54, 54); background-color: rgb(255, 255, 255); font-family: Menlo, Monaco, "Courier New", monospace; font-weight: 800; font-size: 10px; line-height: 15px; white-space: pre;" class=""><div class=""><span style="color: rgb(63, 151, 223);" class="">static</span> <span style="color: rgb(63, 151, 223);" class="">void</span></div><div class=""><span style="color: rgb(99, 99, 36);" class="">cb_message</span> (GstBus * bus, GstMessage * msg, GstElement* pipeline)</div><div class="">{</div><div class=""> <span style="color: rgb(99, 99, 36);" class="">INFO</span>(<span style="color: rgb(162, 86, 55);" class="">"bus message: "</span> + <span style="color: rgb(70, 224, 192);" class="">std</span>::<span style="color: rgb(99, 99, 36);" class="">string</span>(<span style="color: rgb(99, 99, 36);" class="">gst_message_type_get_name</span>(<span style="color: rgb(99, 99, 36);" class="">GST_MESSAGE_TYPE</span> (msg))));</div><div class="">}</div></div></div><div><br class=""></div><div>But this is remain silent as well.</div><div><br class=""></div><div><br class=""></div><div>So is there a way to configure this behaviour /<span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class=""> </span><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class="">trigger the log </span> flushing externally?
