gstreamer suddenly stops rtsp

[Erhan Y.]

We have hikvision dvr and we use rtsp udp to get streams from the DVR. Gstreamer is working on an embedded ARM based board (NXP i.mx8m).When we start two streams from this embedded board and from a PC, the embedded boards stops after 8-10 minutes. But the PC continue running.The error is :0:14:28.863922625   650 0xffff84003e30 FIXME           rtph265depay gstrtph265depay.c:1310:gst_rtp_h265_depay_process:<rtph265depay0> Assuming DONL field is not present0:14:28.864027500   650 0xffff84003e30 FIXME           rtph265depay gstrtph265depay.c:1310:gst_rtp_h265_depay_process:<rtph265depay0> Assuming DONL field is not present0:14:29.163059625   650 0xaaaaf9d64050 WARN                 rtspsrc gstrtspsrc.c:5636:gst_rtspsrc_loop_udp:<rtspsrc0> warning: Unhandled return value -7.0:14:29.195225500   650 0xaaaaf9d64050 INFO        GST_ERROR_SYSTEM gstelement.c:2140:gst_element_message_full_with_details:<rtspsrc0> posting message: Could not read from resource.0:14:29.195360375   650 0xaaaaf9d64050 INFO        GST_ERROR_SYSTEM gstelement.c:2167:gst_element_message_full_with_details:<rtspsrc0> posted warning message: Could not read from resource.0:14:29.195405000   650 0xaaaaf9d64050 WARN                 rtspsrc gstrtspsrc.c:5704:gst_rtspsrc_loop_udp:<rtspsrc0> error: Could not receive message.
