From c5fda68403b74911d0b2e2ab2b1e58c52ab3dad7 Mon Sep 17 00:00:00 2001 From: He Junyan Date: Wed, 4 Aug 2021 15:02:01 +0800 Subject: x265: Fix a deadlock when failing to create the x265enc. The GST_ELEMENT_ERROR will call the gst_object_get_path_string and use gst_object_get_parent to get the full object path name, which needs to lock the object. But we are already in a locked context and so this will cause a deadlock, the pipeline can not exit normally.
