Description Loïc Minier 2006-05-26 20:16:20 UTC 
Hi,

This segfaults here:
/usr/bin/gst-launch-0.10 --gst-debug=1 --gst-plugin-path=/usr/lib/gstreamer-0.10

(not that it's a --gst-debug, instead of --gst-debug-level)

(gdb) run --gst-debug=1 --gst-plugin-path=/usr/lib/gstreamer-0.10  --gst-disable
-segtrap
Starting program: /usr/bin/gst-launch-0.10 --gst-debug=1 --gst-plugin-path=/usr/
lib/gstreamer-0.10  --gst-disable-segtrap
(gdb) bt

minimally invasive patch

Crashes parsing caps. Not that surprising, since all the GStreamer types etc. are registered only in post_init.

Maybe we should just move them to pre_init - not sure. Attached patch is minimally invasive.

       * gst/gst.c: (add_path_func), (init_post):
         Don't scan registry paths passed via --gst-plugin--path immediately
         (will crash, because absolutely nothing is set up and no types are
         registered etc.); do this later in init_post(). Fixes #343057.
