The data I obtained is in AV_PIX_FMT_YUVJ422P format, how to convert it to YUV?

static void YUV420PPackages(uint8_t *yuv420, uint8_t *y_ptr, uint8_t *u_ptr,
uint8_t *v_ptr, int width, int height)
{
int yLen = width * height;
int uvLen = width / 2 * height / 2;
memcpy((unsigned char *)yuv420, y_ptr, yLen);
memcpy((unsigned char *)yuv420 + yLen, u_ptr, uvLen);
memcpy((unsigned char *)yuv420+yLen+uvLen, v_ptr, uvLen);
}
YUV420PPackages(buf, pVideoFrame->data[0], pVideoFrame->data[1], pVideoFrame->data[2], pCodecCtx->width, pCodecCtx->height);
