FFMPEG with javaCV can't open stream -

i having strange behavior when testing video stream of mobotix camera, i'm using javacv 0.11. when set timeout can't open stream, stream open if don't set timeout parameter.

i verified behavior javacv 0.11 , java cv 0.11 in version 0.9 , 0.8 works timeout.

probably error of lib javacv or way i'm using :p

my question ffmpeg experts following:

when i'm calling:

avformat_open_input 

the function returns -138

i called function av_strerror fir error code , function returned "error number -138 occurred".

a description not useful, can tell me error means?

error -138 flags timeout.

from errno.h:

#define etimedout       138
