<div dir="ltr">I've set GST_DEBUG to "encodebin:6". I've got all kinds of all good info during encodebin initialization (I will copy it below my report). All the debug messages were posted before pipeline started to run and there was absolutely nothing until the sudden crash at the bold line in my code below. The piece of code that produces the crash is here (in the bus callback):<div><br></div><div><div> case GST_MESSAGE_EOS: </div><div> g_print("EOS received on OBJ NAME %s\n",GST_OBJECT_NAME(msg->src));</div><div><span class="" style="white-space:pre"> </span><b>gst_element_set_state (pipeline, GST_STATE_READY);</b></div><div><span class="" style="white-space:pre"> </span> gst_element_set_state (pipeline, GST_STATE_PLAYING);</div><div> break; </div><div><br></div><div>If I change my encoding to H264 - this code runs normally and restart the pipeline without any problem.</div><div>Below is the debug output - there's nothing at all after the pipeline starts running.</div><div><br></div><div>Again, if I replace <b>gst_element_set_state (pipeline, GST_STATE_READY);</b> line with <b>gst_element_set_state (<element_name>, GST_STATE_READY); </b>where <element_name> is any element except for encodebin then gstreamer doesn't crash. It only crashes when I command the pipeline or encodebin to stop. It looks to me that gstreamer crashes when I try to bring encodebin to the stopped state, which is something to do with inability to sync the encodebin clock with the rest of the

</span>You just set GST_DEBUG=6 in the environment like on other platforms, or<br>
call gst_debug_set_default_threshold(6) in your code.<br>
<br>
For getting a backtrace you will have to run your application in gdb<br>
and make it crash. You can get gdb binaries from here:<br>
