使用g_object_set / strchr的分段错误

Question

这行让我出现了分段错误 ：

g_object_set(G_OBJECT(data.udpsrc), "port", 5000, "caps", caps, NULL);

哪里

• data.udpsrc = gst_element_factory_make("udpsrc", "source");
• caps = gst_caps_new_empty_simple("application/x-rtp");

这是gdb的输出：

Program received signal SIGSEGV, Segmentation fault.
strchr () at ../ports/sysdeps/arm/armv6/strchr.S:28
28  ../ports/sysdeps/arm/armv6/strchr.S: No such file or directory.

这是错误740191 。 您至少需要将Gstreamer更新到1.4.5版本。
