初始化摄像头.pixel_format = PIXFORMAT_RGB565后，修改为PIXFORMAT_JPEG出现的问题

[Letian-stu]

你好，我一开始想初始化ov2640获取的像素格式为rgb565，在初始化成功后修改为jpge出现错误，能不能这样修改模式，我的代码如下:

static camera_config_t camera_config = {
    .pin_pwdn = CAM_PIN_PWDN,
    .pin_reset = CAM_PIN_RESET,
    .pin_xclk = CAM_PIN_XCLK,
    .pin_sccb_sda = CAM_PIN_SIOD,
    .pin_sccb_scl = CAM_PIN_SIOC,

    .pin_d7 = CAM_PIN_D7,
    .pin_d6 = CAM_PIN_D6,
    .pin_d5 = CAM_PIN_D5,
    .pin_d4 = CAM_PIN_D4,
    .pin_d3 = CAM_PIN_D3,
    .pin_d2 = CAM_PIN_D2,
    .pin_d1 = CAM_PIN_D1,
    .pin_d0 = CAM_PIN_D0,
    .pin_vsync = CAM_PIN_VSYNC,
    .pin_href = CAM_PIN_HREF,
    .pin_pclk = CAM_PIN_PCLK,

    .xclk_freq_hz = 20000000,
    .ledc_timer = LEDC_TIMER_0,
    .ledc_channel = LEDC_CHANNEL_0,

    .pixel_format = PIXFORMAT_RGB565,
    .frame_size = FRAMESIZE_QVGA, 
    .jpeg_quality = 32, 
    .fb_count = 1,                  
};
esp_err_t cam_config_init(void)
{
    esp_err_t err = esp_camera_init(&camera_config);
    if (err != ESP_OK)
    {
        ESP_LOGE(TAG, "Camera Init Failed");
        return ESP_FAIL;
    }
    else
    {
        ESP_LOGI(TAG, "Camera Init Succrss");
    }
    sensor_t *camera_cfg = esp_camera_sensor_get();
    camera_cfg->set_pixformat(camera_cfg, PIXFORMAT_JPEG );
    camera_cfg->set_framesize(camera_cfg, FRAMESIZE_QVGA );
    ESP_LOGE(TAG, "Camera Init change ok");
    return ESP_OK;
}

这个sensor 不支持直接更改输出格式。需要重新调用 esp_camera_init() 更改输出格式。
