안녕하세요..

ffmpeg 을 보다가 궁금한 문법이 있어서 이렇게 질문드립니다..

 .pix_fmts       = (const enum PixelFormat[]) {PIX_FMT_GRAY8, PIX_FMT_NONE}, 이부분이

어떻게 동작하는지 잘모르겠네요..

pix_fmts 에 주소값이 들어가는것 같은데..

고수님들 좀 갈쳐주세요..

enum PixelFormat {

    PIX_FMT_NONE= -1,

    PIX_FMT_YUV420P,   ///< planar YUV 4:2:0, 12bpp, (1 Cr & Cb sample per 2x2 Y samples)

    PIX_FMT_YUYV422,   ///< packed YUV 4:2:2, 16bpp, Y0 Cb Y1 Cr

    PIX_FMT_RGB24,     ///< packed RGB 8:8:8, 24bpp, RGBRGB...

    PIX_FMT_BGR24,     ///< packed RGB 8:8:8, 24bpp, BGRBGR...

    PIX_FMT_YUV422P,   ///< planar YUV 4:2:2, 16bpp, (1 Cr & Cb sample per 2x1 Y samples)

    PIX_FMT_YUV444P,   ///< planar YUV 4:4:4, 24bpp, (1 Cr & Cb sample per 1x1 Y samples)

    PIX_FMT_YUV410P,   ///< planar YUV 4:1:0,  9bpp, (1 Cr & Cb sample per 4x4 Y samples)

    PIX_FMT_YUV411P,   ///< planar YUV 4:1:1, 12bpp, (1 Cr & Cb sample per 4x1 Y samples)

    PIX_FMT_GRAY8,     ///<        Y        ,  8bpp

};

typedef struct AVCodec {

    const enum PixelFormat *pix_fmts;       

} AVCodec;

AVCodec ff_a64multi_encoder = {

    .pix_fmts       = (const enum PixelFormat[]) {PIX_FMT_GRAY8, PIX_FMT_NONE},

};
