使用libjpeg-turbo将jpeg转换为YUV

非常感谢您的提问。使用libjpeg-turbo将jpeg转换为YUV的代码如下：

#include <stdio.h>
#include <jpeglib.h>

int main(int argc, char *argv[]) {
    struct jpeg_decompress_struct cinfo;
    struct jpeg_error_mgr jerr;
    FILE *infile;
    JSAMPARRAY buffer;
    int row_stride;

    if (argc != 2) {
        fprintf(stderr, "Usage: %s <input file>\n", argv[0]);
        return 1;
    }

    if ((infile = fopen(argv[1], "rb")) == NULL) {
        fprintf(stderr, "Can't open %s\n", argv[1]);
        return 1;
    }

    cinfo.err = jpeg_std_error(&jerr);
    jpeg_create_decompress(&cinfo);
    jpeg_stdio_src(&cinfo, infile);
    (void) jpeg_read_header(&cinfo, TRUE);
    (void) jpeg_start_decompress(&cinfo);

    row_stride = cinfo.output_width * cinfo.output_components;
    buffer = (*cinfo.mem->alloc_sarray)
            ((j_common_ptr) &cinfo, JPOOL_IMAGE, row_stride, 1);

    while (cinfo.output_scanline < cinfo.output_height) {
        (void) jpeg_read_scanlines(&cinfo, buffer, 1);
        // Do something with the YUV data here
    }

    (void) jpeg_finish_decompress(&cinfo);
    jpeg_destroy_decompress(&cinfo);
    fclose(infile);
    return 0;
}

希望这个代码能够帮助您。如果您有任何其他问题，请随时问我。
