Hi All,
I have written an application in which i try to create an "alsasink" element. But at times it aborts, with the following stack.... (At times it works just fine)

Replying to Self:
All,
This crash is gst_element_factory_make(), is happening for almost all the elements randomly. Even the gst_bin_new is failing, is there something wrong with my environment? (But there are times when the same code works just very fine.)
Please help.

hi,
you seem to be using gstreamer code and base 0.10.23, we are now at 0.10.34. Please consider upgrading, also ensure you use a recent glib. There where many thread safety issues that are nowadays solved in both libraries. Stefan On 06/13/2011 09:00 AM, Ashwini Sharma wrote:

glib-2.0 is not the full version. But anyway, you could file a bug, attach the stack trace and if possible a link to where we can have a look at your source code. If you can provide a small standalone example that causes the issue, we might be able to solve it quickly. Stefan
