Hi folks,
When using mediastreamer through libjingle I'm getting a segmentation fault in snd_card_create_read_filter. I'm having a hard time understanding whats going wrong or how to fix it. I've pasted the gdb output below -- if someone, anyone, knows whats going on, please help me -- i've been killing myself trying to get this to work.
Thanks, George
