    v4l2: fix build break using V4L2_CAP_VIDEO_M2M_MPLANE
    
    This may not be defined. Since the previous version used
    only the other define (V4L2_CAP_VIDEO_OUTPUT_MPLANE), fall
    back on this only when not available.
Comment 2 Nicolas Dufresne (ndufresne) 2014-01-13 15:35:51 UTC 
Thansk, we usually define the missing define, but this should work just right. We should consider a v4l2-compat.h, it's kind of tricky sine this API has no version.
