When encoding a frame, red_worker passes an allocated buffer to libjpeg where it should encode the frame. When it fails, a new bigger buffer is allocated and the encoding is restarted from scratch. However, it's possible to use libjpeg to realloc this buffer if it gets too small during the encoding process. Make use of this feature, especially since it will make it easier to encore one line at a time instead of a full frame in subsequent commits.
