Double looking at it, there are two problems:
1) in_buffer is an array of integers, but the index used for accessing it
(frame_byte_size*i) is computed thinking that it is an array of bytes...
Fixing this problem, the most subtle crash goes away
2) there is a meaningless "fclose(f)" in the code... Removing it, the other
crash is fixed
I still think that this program is searching for problems, and that using
libavdevice would be a superior solution.
