Reading streaming video frame by frame

[isak3t]

Hello Sir,

Currently the callback function itself is not being called.
I have included a line *printf("frame signal\n");* in beginnning of
frame_func fucntion but it is not printed.

The only output on console is :
state will change async



Additonally,
Trying your code in frame_func give the error as *GstAppSink  undeclared*
Is there a specific header to be included for it?
