I think they didn't build and/or they were not part of the original Cinder OpenCV libs, so I disabled them, to make it build faster.

Thanks for the comment. I agree. Renamed the cmake file.

This issue still persists. using `height-1` in the crashing line seems to be working more or less. ``` sws_scale(imgctx, (const uint8_t* const*) &data, &stride, 0, height-1, frame->data, frame->linesize); ```

@gonzalovinas it is described in the README Configuration section.
