+title: MaixCAM MaixPy Video Streaming UVC Streaming / As a UVC camera to display custom image
+update:
+  - date: 2024-12-20

+
+## Introduction
+
+`MaixCAM` as a `UVC camera`, where `UVC` stands for `USB video(device) class`.
+
+Here, two methods are provided to display custom content:
+
+- Refresh the target image using the `show` method of `maix.uvc.UvcStreamer` (supports YUYV and MJPEG).
+- Refresh the target image by registering a custom image refresh callback function with `maix.uvc.UvcServer` (only supports MJPEG). Much more complex than the method above.
+
+
+## Example
+
+**First, you need to enable the `UVC` function in the `USB settings` section of the `Settings` app.**
+
+**Note:**  
+Once the `UVC` function is enabled, due to Linux's implementation of the `UVC Gadget`, a user program is still required to handle `UVC` device events.  
+Otherwise, the entire `USB` functionality will pause and wait, affecting other simultaneously enabled `Gadget` features like `Rndis` and `NCM`, which may cause network disconnection.  
+Therefore, for users who also need other `USB` functionalities, it is recommended to use the `UvcStreamer` method when developing UVC display functionality based on `MaixPy`.  
+Otherwise, ensure that the `MaixCAM` device has other network access methods, such as `WIFI`, to ensure proper development and debugging.
+
+
+### UvcStreamer
+
+This method does not affect normal USB functionality. The underlying principle is to split the task into two processes. The official implementation uses a `server` process to handle `UVC` device events and encapsulates an easy-to-use, unified image refresh interface `show(img)` for users. You can treat it as a simple `display` linear logic operation.
+
+**Reference example source code path:**  
+`MaixPy/examples/vision/streaming/uvc_stream.py`
+
+### **Example Source (Usage Instructions):**
+
+1. **Initialize the UvcStreamer object**
+
+```python
+uvcs = uvc.UvcStreamer()
+```
+
+- (Optional) Switch to MJPEG streaming mode (YUYV default)
+
+```python
+uvcs.use_mjpg(1)
+```
+
+2. Refresh the image (automatically handles the format, medium performance loss for MJPEG, and high loss for YUYV)
+
+```python
+uvcs.show(img)
+```
+
+### UvcServer
+
+This approach offers high performance with a single-process implementation, but USB functionality will only be available when the process is running. Therefore, when stopping this process, it's important to note that the enabled `Rndis` and `NCM` functionalities will temporarily become inactive, causing a network disconnection.
+
+**Reference example source code path:**  
+`MaixPy/examples/vision/streaming/uvc_stream.py`
+
+**Also packaged as an app source code path:**  
+`MaixCDK/projects/app_uvc_camera/main/src/main.cpp`
+
+### **Example Source (Usage Instructions):**
+
+1. **Initialize the UvcServer object (requires a callback function for image refresh)**
+
+A helper function `helper_fill_mjpg_image` is provided to assist in placing more general `Image` objects into the `UVC` buffer.
+
+```python
+cam = camera.Camera(640, 360, fps=60)   # Manually set resolution
+                                        # | 手动设置分辨率
+
+def fill_mjpg_img_cb(buf, size):
+    img = cam.read()
+    return uvc.helper_fill_mjpg_image(buf, size, img)
+
+uvcs = uvc.UvcServer(fill_mjpg_img_cb)
+```
+The reference implementation will `fill_mjpg_img_cb` only trigger a buffer refresh when it returns `0`.  
+Therefore, it is recommended to use the helper function in the last line:
+`return uvc.helper_fill_mjpg_image(buf, size, img)`
+
+2. Start the UVC, which launches a background thread, non-blocking operation:
+
+```python
+uvcs.run()
+```
+
+3. Stop the UVC when it's no longer needed. This will restore the background process from the `UvcStreamer` method implementation to ensure normal USB functionality.
+
+Currently, there is a **BUG** in the MaixPy framework where it forcibly terminates processes upon exit, preventing the functions after the `while not app.need_exit():` loop from being executed, meaning the `stop()` method may not run as expected.  
+Therefore, for users who require **normal USB functionality**, it is recommended to switch to the `UvcStreamer` method or use the original C++ API from **MaixCDK**.  
+
+**Reference example:**  
+`MaixCDK/examples/uvc_demo/main/src/main.cpp`
+
+```python
+uvcs.stop()
+```

+title: MaixCAM MaixPy 视频流 UVC 推流 / 化身 UVC 摄像头显示自定义内容
+update:
+  - date: 2024-12-20
+    author: taorye
+    version: 1.0.0
+    content: 初版文档
+---
+
+## 简介
+
+`MaixCAM` 化身 `UVC 摄像头`, `UVC` 全称为：USB video(device) class，这里提供两种方法供显示自定义内容:
+
+- 通过 `maix.uvc.UvcStreamer` 的 `show` 方法来刷新目标图片（支持 YUYV 和 MJPEG），
+- 通过 `maix.uvc.UvcServer` 注册自定义刷图回调函数来刷新目标图片（仅支持 MJPEG），区别于上一个方法的顺序逻辑，使用有一定的难度
+
+## 参考例程
+
+首先需要在 `Settings` APP 的 `USB settings` 栏内启用 `UVC` 功能。
+
+注意： `UVC` 功能启用后，因为 Linux 的 `UVC Gadget` 实现，仍需一个用户程序处理 `UVC` 设备的事件，
+否则整个 `USB` 功能会暂停等待，影响同时启用的其它 `Gadget` 功能，包括 `Rndis` 和 `NCM`，导致断网。
+故对于其它 `USB` 功能有需求的用户，在基于 `MaixPy` 开发 UVC 显示功能时建议采用 `UvcStreamer` 的实现。
+否则请保证 `MaixCAM` 设备有其它联网途径如 `WIFI` 以确保能正常开发调试。
+
+### UvcStreamer
+
+该方法不影响常态下 USB 功能，原理是分了两个进程。官方默认实现了一个 `server` 进程进行`UVC` 设备的事件处理，并封装了易用统一的刷图接口 `show(img)` 供用户使用，当成一个 `display` 线性逻辑操作即可。
+
+参考示例源码路径： `MaixPy/examples/vision/streaming/uvc_stream.py`
+
+示例分析（使用方法）：
+
+1. 初始化 UvcStreamer 对象
+
+```python
+uvcs = uvc.UvcStreamer()
+```
+
+- （可选）切换成 MJPEG 模式，默认 YUYV
+
+```python
+uvcs.use_mjpg(1)
+```
+
+2. 刷图（自动处理格式，MJPEG 中等性能损耗，YUYV 高损耗）
+
+```python
+uvcs.show(img)
+```
+
+
+### UvcServer
+
+高性能单进程实现，但仅在运行时 USB 全部功能才可用，故停止该进程时需要注意仍启用的 `Rndis` 和 `NCM` 会暂时失效，断开网络链接。
+
+参考示例源码路径：`MaixPy/examples/vision/streaming/uvc_stream.py`
+
+另有封装成 APP 的源码路径：`MaixCDK/projects/app_uvc_camera/main/src/main.cpp`
+
+示例分析（使用方法）：
+
+1. 初始化 UvcServer 对象，需提供刷图回调函数实现
+
+提供了 helper 函数 `helper_fill_mjpg_image` 帮助将更通用的 `Image` 对象刷入 `UVC` 的缓冲区。
+
+```python
+cam = camera.Camera(640, 360, fps=60)   # Manually set resolution
+                                        # | 手动设置分辨率
+
+def fill_mjpg_img_cb(buf, size):
+    img = cam.read()
+    return uvc.helper_fill_mjpg_image(buf, size, img)
+
+uvcs = uvc.UvcServer(fill_mjpg_img_cb)
+```
+`fill_mjpg_img_cb` 参考实现仅当返回 `0` 时，才会正常触发缓冲区刷新。
+故推荐在最后一行使用 helper 函数即可：
+`return uvc.helper_fill_mjpg_image(buf, size, img)`
+
+2. 启动 uvc，后台启动线程，非阻塞
+
+```python
+uvcs.run()
+```
+
+3. 停止 uvc，不再使用时需要调用，可恢复 `UvcStreamer` 方法实现中的后台进程，保证 `USB` 功能正常
+
+目前有 BUG，MaixPy 框架在退出时会强制终止进程，导致并不能执行完 `while not app.need_exit():` 循环后的函数调用，即该 `stop()` 很难得到执行。
+故对 **保证 `USB` 功能正常** 有需求的用户可以换用 `UvcStreamer` 方法或是移步 `MaixCDK` 的原始 C++ API，参考例程：`MaixCDK/examples/uvc_demo/main/src/main.cpp`。
+
+```python
+uvcs.stop()
+```
