I think I have reproduced this though it's not systematic. Setting GST_DEBUG=4 I noticed some messages indicating that the process is running out of file descriptors. Indeed a look into /proc showed 4096 file descriptors open. 0:03:01.185809093 26935 0x7f0bdd06cf20 WARN GST_POLL gstpoll.c:602:gst_poll_new: 0x7f0be9890190: can't create socket pair ! (Xorg:26935): GStreamer-CRITICAL **: gst_poll_write_control: assertion 'set != NULL' failed My current theory is that hovering over the video seek bar results in the stream size changing all the time which is compounded by the fact that the video is split across 3 or 4 streams. This causes the GStreamer encoder to keep rebuilding the pipeline which I suspect leaks these socket pairs. I still need to pinpoint the exact source of the leak and particularly whether it is caused by a bug in the GStreamer encoder or in GStreamer itself. -- Francois Gouget <fgou...@codeweavers.com> _______________________________________________ Spice-devel mailing list Spice-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/spice-devel
