Description Adrien CLERC 2016-02-02 10:22:06 UTC 
I have this really simple program:

#include <gst/gst.h>
int main( int argc, char** argv )
{
    const gchar * string_uri = "http://admin:admin@127.0.0.1/media/info?test=1";
    GstUri * parsed_uri = gst_uri_from_string(string_uri);
    return 0;
}


It segfault, apparently with the following stack:

(gdb) bt full

+ Trace 235944

  • #0 gst_mini_object_init
    at gstminiobject.c line 133
  • #1 _gst_uri_new
    at gsturi.c line 1019
  • #2 gst_uri_from_string
    at gsturi.c line 1535
  • #3 main(int, char**)
    at main.cpp line 25 

I wasn't able to test with 1.6.3, but I didn't see any commit that improved the situation. Did I missed something?
Comment 1 Adrien CLERC 2016-02-02 10:23:59 UTC 
Sorry, the backtrace from the initial description is not really the one from the included source code, I was testing with some printf.
But it fails on gst_uri_from_string.
Comment 2 Tim-Philipp Müller 2016-02-02 10:32:02 UTC 
I think you need to call gst_init() before using this API.
Comment 3 Adrien CLERC 2016-02-02 10:37:35 UTC 
OK. Adding call gst_init works. I may have missed it in the documentation, but this requirements is nowhere to be found in the GstUri page.
Comment 4 Tim-Philipp Müller 2016-02-02 10:41:04 UTC 
It pretty much applies to all GStreamer API, unless explicitly mentioned otherwise  :) I'll check if I can add a guard somewhere..

Comment 6 Thibault Saunier 2016-02-02 10:59:48 UTC 
We will end up adding guards like that all around if we go that way ;)
Comment 7 Adrien CLERC 2016-02-02 11:00:24 UTC 
Wow. Incredible reactivity time. Many thanks for making Gstreamer an awesome software!
