* \brief initialize mjpeg encoder
*
* This routine is to set up the parameters and initialize the mjpeg encoder.
* It does all the initializations needed of lower level routines.
* The formats accepted by this encoder is YUV422P and YUV420
*
* \param w width in pixels of the image to encode, must be a multiple of 16
* \param h height in pixels of the image to encode, must be a multiple of 8
* \param y_rsize size of each plane row Y component
* \param y_rsize size of each plane row U component
* \param v_rsize size of each plane row V component
* \param cu "cheap upsample". Set to 0 for YUV422 format, 1 for YUV420 format
* when set to 1, the encoder will assume that there is only half th
* number of rows of chroma information, and every chroma row is
* duplicated.
* \param q quality parameter for the mjpeg encode. Between 1 and 20 where 1
* is best quality and 20 is the worst quality.
* \param b monochrome flag. When set to 1, the mjpeg output is monochrome.
* In that case, the colour information is omitted, and actually the
* colour planes are not touched.
*
* \returns an appropriately set up jpeg_enc_t structure
*
* The actual plane buffer addreses are passed by jpeg_enc_frame().
*
* The encoder doesn't know anything about interlacing, the halve height
* needs to be passed and the double rowstride. Which field gets encoded
* is decided by what buffers are passed to mjpeg_encode_frame()
