[Linphone-developers] Segmentation Fault with snd_card_create_read_filter

[George A. Papayiannis]

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
