uvc摄像头例子通讯报错 (AEGHB-844) #157
Description
开发板：esp32s2-Saola-v1.2
开发环境：win10 + IDFv4.4 + esp iot solution
摄像头：USB2.0 uvc免驱支持MJPEG摄像头
我根据摄像头描述符配置了usb_camera_wifi_transfer例程的参数后烧写测试，发现在通讯之后报错“SWAP NO EOF ”。
运行log

我的配置：
uvc_config_t uvc_config = {
.dev_speed = USB_SPEED_FULL, //固定为 USB_SPEED_FULL
.configuration = 1, //配置描述符编号，一般为 1
.format_index = 2, // MJPEG 对应的 bFormatIndex, bFormatIndex: 0x02 (2)
.frame_width = 160, // MJPEG 横向像素，例如 320
.frame_height = 120, // MJPEG 纵向像素，例如 240
.frame_index = 5, //MJPEG 320*240 对应的 bFrameIndex, bFrameIndex: 0x05
.frame_interval = 333333, //可选的帧率 dwFrameInterval，例如 30fps
.interface = 1, // 可选的视频流接口 bInterfaceNumber，一般为 1
.interface_alt = 4, // 接口选项 bAlternateSetting, bAlternateSetting: 0x04
.isoc_ep_addr = 0x82, // 接口选项对应的 bEndpointAddress, bEndpointAddresS: 0x82 (Direction=IN EndpointID=2)
.isoc_ep_mps = 512, // 接口选项的确定的 MPS， 例如为 512
.xfer_buffer_size = 20*1024, //单帧图像大小，需要根据实际测试确定，320*240 一般小于 35KB
.xfer_buffer_a = pointer_buffer_a, // 已经申请的 buffer 指针
.xfer_buffer_b = pointer_buffer_b, // 已经申请的 buffer 指针
.frame_buffer_size = 20*1024, //单帧图像大小，需要根据实际测试确定
.frame_buffer = pointer_frame_buffer, // 已经申请的 buffer 指针
};
摄像头描述符,我是用win10的软件获取的，比较多
摄像头描述符.txt
请问可能是什么问题导致的？uvc协议还在学习中不是很明白，是描述符配置的不对还是摄像头本身就不支持？或者说例程需要改动？
