Ok, there is no check of buf_size==0 now, when buf_size==0 END_NOT_FOUND  is

After calling ff_combine_frame I added check of buf_size==0, to check whether 
there is  anything in the buffer.

after rebuilding it more readable for me.I moved the condition with 
frame_in_buffer few lines up, so that it should work now.

I've changed to while().
