I made those commits into new series,  you probably want to rename this to 0009-*.patch... I do not think old 0008 patch will do any good - GReen-BLue-REd planar float format is not something Cin easily can convert for internal use (I saw similar comment in oiio sources... I am not good enough for adding even simple format to ffmpeg/swscale.. even with already written examples) 

from

https://github.com/OpenImageIO/oiio/blob/master/src/ffmpeg.imageio/ffmpeginput.cpp

case AV_PIX_FMT_GBRPF32BE:
    case AV_PIX_FMT_GBRPF32LE:
        nchannels = 3;
        datatype = TypeFloat;
        m_dst_pix_format = AV_PIX_FMT_RGB48; // ? AV_PIX_FMT_GBRPF32
        // FIXME: They don't have a type for RGB float, only GBR float.
        // Yuck. Punt for now and save as uint16 RGB. If people care, we
        // can return and ask for GBR float and swap order.
        break;

I tried to compile with the two patches 0007 and 0008, but the
compilation gives an error. I append the cin5.log, if it helps.
