{props.video_overlay}
+- 采集 HDMI 音频：{props.audio_overlay}
+
+:::note 说明
+
+- 只采集视频时可以只启用视频项；需要音频时必须同时启用两项。
+- 不要同时启用其他占用同一个 MIPI CSI 接口或 {props.audio_bus} 引脚的 Overlay。
+
+:::
+
+保存设置后重启系统：
+
+
+
+```bash
+sudo reboot
+```
+
+
+
+## 检查设备
+
+使用以下命令确认 RK628 是否被正确识别：
+
+
+
+```bash
+sudo dmesg | grep -i rk628
+```
+
+
+
+正确识别时会输出类似信息，出现 `rk628-csi-v4l2 found` 和 `New format` 后即可继续测试：
+
+```text
+RK628 I2C driver version: 00.01.00
+rk628 version is: RK628F/H (20230321)
+rk628-csi-v4l2 found @ 0xa0 (rk3x-i2c)
+rk628_csi_format_change: New format: 1920x1080p60.00 (2200x1125)
+```
+
+## 采集 HDMI 音视频
+
+### 采集 HDMI 视频
+
+在主板的图形桌面终端运行以下命令：
+
+
+ {`gst-launch-1.0 -e -v \\
+ v4l2src device=${props.video_dev} do-timestamp=true ! \\
+ video/x-raw,format=NV16,width=1920,height=1080,framerate=30/1 ! \\
+ queue ! videoconvert ! glimagesink sync=true`}
+
+
+正常情况下桌面会出现 HDMI 预览画面，按 `Ctrl+C` 停止运行。
+
+如果画面出现花屏等现象，可以关闭主板电源，重新检查硬件连接后再次测试。
+
+
+
+
+ {`v4l2-ctl -d ${props.video_dev} \\
+ --set-fmt-video=width=1920,height=1080,pixelformat=NV12 \\
+ --stream-mmap=3 --stream-poll \\
+ --stream-count=480 --stream-to=/dev/null \\
+ >/dev/null 2>&1 &
+VIDEO_PID=$!
+
+sleep 1
+
+arecord \\
+ -D hw:CARD=${props.audio_capture_card},DEV=0 \\
+ -f S16_LE -r 48000 -c 2 \\
+ -d 5 -t wav \\
+ rk628-audio.wav
+
+wait "$VIDEO_PID"`}
+
+
+视频数据写入 `/dev/null`，不会生成视频文件。
+
+### 播放录音
+
+
+ {`aplay -D plughw:CARD=${props.audio_playback_card},DEV=0 rk628-audio.wav`}
+
+
+### 同时播放视频和声音
+
+确认主板已连接耳机或音箱，并且 HDMI 输出设备的音频已经输出到 HDMI，然后在主板的图形桌面终端运行：
+
+
+ {`gst-launch-1.0 -e -v \\
+ v4l2src device=${props.video_dev} do-timestamp=true ! \\
+ video/x-raw,format=NV16,width=1920,height=1080,framerate=30/1 ! \\
+ queue ! videoconvert ! glimagesink sync=true \\
+ alsasrc device="hw:CARD=${props.audio_capture_card},DEV=0" do-timestamp=true ! \\
+ audio/x-raw,format=S16LE,rate=48000,channels=2 ! \\
+ queue ! audioconvert ! audioresample ! \\
+ alsasink device="plughw:CARD=${props.audio_playback_card},DEV=0" sync=true`}
+
+
+正常情况下，桌面会显示 HDMI 画面，主板音频输出口会播放 HDMI 声音。
+
+## 常见问题
+
+### 没有 RK628 日志？
+
+检查 Overlay 是否已经保存：
+
+
+
+```bash
+grep fdtoverlays /boot/extlinux/extlinux.conf
+```
+
+
+
+音视频采集应该包含：
+
+
+ {`${props.audio_dtbo}\n${props.video_dtbo}`}
+
+
+如果没有 RK628 视频 Overlay，请返回 `rsetup` 重新启用，并检查硬件连接是否正确。
+
+### 一直显示 no signal 或 lock failed？
+
+开机早期短暂出现这些日志不一定是故障。如果后续始终没有 `New format`，请检查：
+
+- HDMI 信号源是否已经开机并开始输出
+- HDMI 线是否可靠
+- FPC 排线是否正确连接
+
+### 不确定 RK628 对应哪个视频节点？
+
+不同系统或 Overlay 配置下，视频节点编号可能变化，可以按以下步骤查找。
+
+查找 RK628 所在的媒体设备：
+
+
+
+```bash
+for m in /dev/media*; do media-ctl -p -d "$m" 2>/dev/null | grep -qi rk628 && echo "RK628 位于 $m"; done
+```
+
+
+
+查询主视频采集节点：
+
+
+
+```bash
+media-ctl -d /dev/media0 -e 'stream_cif_mipi_id0'
+```
+
+
+
+如果输出的节点不是 {props.video_dev}，请把教程命令中的视频节点替换为实际节点。
+
+采集 30 帧验证节点：
+
+
+ {`v4l2-ctl --verbose -d ${props.video_dev} --set-fmt-video=width=1920,height=1080,pixelformat=NV12 --stream-mmap=3 --stream-poll --stream-count=30 --stream-to=/dev/null`}
+
+
+如果终端连续输出 `cap dqbuf` 帧信息并正常结束，说明视频节点选择正确。
+
+### 不确定 HDMI 音频对应哪个设备？
+
+不同系统版本或硬件配置下，声卡编号可能不同，重启后也可能变化，可以按以下步骤查找。
+
+查找 HDMI 音频采集设备：
+
+
+
+```bash
+arecord -l
+```
+
+
+
+启用音频 Overlay 后，应该能找到包含 {props.audio_capture_card} 的设备：
+
+- 声卡名称：{props.audio_capture_card}
+- 设备编号：0
+- 录音命令应使用 hw:CARD={props.audio_capture_card},DEV=0
+
+:::info 说明
+
+`arecord -l` 显示的 `card N` 编号由系统临时分配，重启后可能改变，因此不建议在命令中固定写成 `hw:N,0`。
+
+:::
+
+如果 `arecord -l` 中没有 {props.audio_capture_card}，请检查是否启用了音频 Overlay，并在保存后重启系统。
+
+查找声音播放设备：
+
+
+
+```bash
+aplay -l
+```
+
+
+
+应能找到包含 {props.audio_playback_card} 的设备，对应的播放设备为 plughw:CARD={props.audio_playback_card},DEV=0。
+
+如果使用 USB 声卡或其他播放设备，请把教程命令中的播放设备替换为 `aplay -l` 显示的实际设备。只录制音频、不在主板上播放时，无需查找播放设备。

+# Radxa 4K HDMI IN to MIPI CSI-2 Adapter
+
+## Introduction
+
+The **Radxa 4K HDMI IN to MIPI CSI-2 Adapter** is based on the Rockchip RK628H video bridge chip. It converts HDMI video signals into MIPI CSI-2 signals and extracts I2S digital audio from the HDMI signal.
+
+The adapter provides both 2-lane and 4-lane MIPI CSI-2 connectors, allowing development boards to quickly interface with HDMI cameras, computers and other high-definition video sources. It is suitable for video capture, image processing and embedded vision applications.
+
+
+
+
+
+
+
+
+
+
{props.video_overlay}
+- Capture HDMI audio: {props.audio_overlay}
+
+:::note Note
+
+- If you only capture video, you can enable the video option alone; when audio is needed, both options must be enabled.
+- Do not enable other overlays that occupy the same MIPI CSI connector or the {props.audio_bus} pins.
+
+:::
+
+Save the settings and reboot:
+
+
+
+```bash
+sudo reboot
+```
+
+
+
+## Check the devices
+
+Use the following command to check whether the RK628 is recognized:
+
+
+
+```bash
+sudo dmesg | grep -i rk628
+```
+
+
+
+When it is recognized correctly, output similar to the following appears. Once `rk628-csi-v4l2 found` and `New format` show up, you can continue testing:
+
+```text
+RK628 I2C driver version: 00.01.00
+rk628 version is: RK628F/H (20230321)
+rk628-csi-v4l2 found @ 0xa0 (rk3x-i2c)
+rk628_csi_format_change: New format: 1920x1080p60.00 (2200x1125)
+```
+
+## Capture HDMI video and audio
+
+### Capture HDMI video
+
+Run the following command in the desktop terminal of the board:
+
+
+ {`gst-launch-1.0 -e -v \\
+ v4l2src device=${props.video_dev} do-timestamp=true ! \\
+ video/x-raw,format=NV16,width=1920,height=1080,framerate=30/1 ! \\
+ queue ! videoconvert ! glimagesink sync=true`}
+
+
+The HDMI preview should appear on the desktop. Press `Ctrl+C` to stop it.
+
+If the picture is corrupted, power off the board, recheck the hardware connection and test again.
+
+
+
+
+ {`v4l2-ctl -d ${props.video_dev} \\
+ --set-fmt-video=width=1920,height=1080,pixelformat=NV12 \\
+ --stream-mmap=3 --stream-poll \\
+ --stream-count=480 --stream-to=/dev/null \\
+ >/dev/null 2>&1 &
+VIDEO_PID=$!
+
+sleep 1
+
+arecord \\
+ -D hw:CARD=${props.audio_capture_card},DEV=0 \\
+ -f S16_LE -r 48000 -c 2 \\
+ -d 5 -t wav \\
+ rk628-audio.wav
+
+wait "$VIDEO_PID"`}
+
+
+The video data is written to `/dev/null`, so no video file is generated.
+
+### Play the recording
+
+
+ {`aplay -D plughw:CARD=${props.audio_playback_card},DEV=0 rk628-audio.wav`}
+
+
+### Play video and audio at the same time
+
+Make sure a headphone or speaker is connected to the board, and that the audio of the HDMI output device is routed to HDMI. Then run the following command in the desktop terminal of the board:
+
+
+ {`gst-launch-1.0 -e -v \\
+ v4l2src device=${props.video_dev} do-timestamp=true ! \\
+ video/x-raw,format=NV16,width=1920,height=1080,framerate=30/1 ! \\
+ queue ! videoconvert ! glimagesink sync=true \\
+ alsasrc device="hw:CARD=${props.audio_capture_card},DEV=0" do-timestamp=true ! \\
+ audio/x-raw,format=S16LE,rate=48000,channels=2 ! \\
+ queue ! audioconvert ! audioresample ! \\
+ alsasink device="plughw:CARD=${props.audio_playback_card},DEV=0" sync=true`}
+
+
+The HDMI picture is displayed on the desktop and the HDMI audio is played through the board's audio output.
+
+## FAQ
+
+### No RK628 log?
+
+Check whether the overlay has been saved:
+
+
+
+```bash
+grep fdtoverlays /boot/extlinux/extlinux.conf
+```
+
+
+
+For video and audio capture it should contain:
+
+
+ {`${props.audio_dtbo}\n${props.video_dtbo}`}
+
+
+If the RK628 video overlay is missing, go back to `rsetup` and enable it again, then check whether the hardware connection is correct.
+
+### It keeps showing "no signal" or "lock failed"?
+
+These logs may briefly appear during early boot and do not necessarily indicate a fault. If `New format` never appears afterwards, check:
+
+- whether the HDMI source is powered on and already outputting a signal
+- whether the HDMI cable is reliable
+- whether the FPC cable is connected correctly
+
+### Not sure which video node the RK628 maps to?
+
+The video node number may change between systems or overlay configurations. Use the following steps to find it.
+
+Find the media device that contains the RK628:
+
+
+
+```bash
+for m in /dev/media*; do media-ctl -p -d "$m" 2>/dev/null | grep -qi rk628 && echo "RK628 is on $m"; done
+```
+
+
+
+Query the main video capture node:
+
+
+
+```bash
+media-ctl -d /dev/media0 -e 'stream_cif_mipi_id0'
+```
+
+
+
+If the output node is not {props.video_dev}, replace the video node in the tutorial commands with the actual one.
+
+Capture 30 frames to verify the node:
+
+
+ {`v4l2-ctl --verbose -d ${props.video_dev} --set-fmt-video=width=1920,height=1080,pixelformat=NV12 --stream-mmap=3 --stream-poll --stream-count=30 --stream-to=/dev/null`}
+
+
+If the terminal keeps printing `cap dqbuf` frame information and finishes normally, the video node is correct.
+
+### Not sure which device the HDMI audio maps to?
+
+The sound card number may differ between system versions or hardware configurations, and may also change after a reboot. Use the following steps to find it.
+
+Find the HDMI audio capture device:
+
+
+
+```bash
+arecord -l
+```
+
+
+
+After the audio overlay is enabled, a device containing {props.audio_capture_card} should be listed:
+
+- Card name: {props.audio_capture_card}
+- Device number: 0
+- The recording command should use hw:CARD={props.audio_capture_card},DEV=0
+
+:::info Note
+
+The `card N` number shown by `arecord -l` is assigned dynamically by the system and may change after a reboot, so it is not recommended to hard-code `hw:N,0` in commands.
+
+:::
+
+If `arecord -l` does not list {props.audio_capture_card}, check whether the audio overlay is enabled and reboot after saving.
+
+Find the audio playback device:
+
+
+
+```bash
+aplay -l
+```
+
+
+
+A device containing {props.audio_playback_card} should be listed, and the corresponding playback device is plughw:CARD={props.audio_playback_card},DEV=0.
+
+If you use a USB sound card or another playback device, replace the playback device in the tutorial commands with the actual one shown by `aplay -l`. If you only record audio and play it elsewhere, no playback device lookup is needed.
