Enable the video engine and add it's optional reserved memory region. Use 32MB for the reserved memory since the video engine could need up to two 1920x1200@32bpp source buffers. Source buffers: 2 * 1920 * 1200 * 4 = 18432000 bytes In addition, the V4L2 subsystem will allocate any number of compression buffers, each at most 1/8th the size of the source buffer.
