Can dm365's h264 encoder encode data in YUV422 format, instead of YUV420 SP?

Hi,

I  want to encode video buffers into h264 format. The following code works fine.

    VIDENC1_Params  encParams;

    memset(&encParams, 0, sizeof(VIDENC1_Params));

    encParams.size                  = sizeof(VIDENC1_Params);
        encParams.encodingPreset        = XDM_HIGH_SPEED;
        encParams.rateControlPreset     = IVIDEO_NONE;
        encParams.maxFrameRate          = 30000;
        encParams.maxBitRate            = 0;
        encParams.maxWidth              = width;
        encParams.maxHeight             = height;
        encParams.inputContentType      = IVIDEO_PROGRESSIVE;
        encParams.inputChromaFormat     = XDM_YUV_420SP;
        encParams.reconChromaFormat     = XDM_YUV_420SP;
        encParams.dataEndianness        = XDM_BYTE;
        encParams.maxInterFrameInterval = 0;


    enc = VIDENC1_create(ce, (char*)ENCODER_NAME, &encParams);

But the buffer I get from video_in is YUV422. So I changed the red line to

     encParams.inputChromaFormat     = XDM_YUV_422P;
     encParams.reconChromaFormat     = XDM_YUV_422P;

Now, VIDENC1_create returns NULL.

So, doesn't h264 encoder support YUV422 format?

Thanks a lot.
