I think the exact simplification is
if (!bytes_per_sec) {
return 0;
}
return frame_size ? bytes_per_sec / frame_size : MJPEG_MAX_FPS;
You already noted that you used rounding instead or truncation;
depending on the usage can be correct or not.
This change that if bytes_per_sec == 0 and frame_size == 0 previous
code returned 0 while now returns MJPEG_MAX_FPS. I think this
is not possible!
