As shown in FIG. 4, the video recording method includes steps S101 to S103.

S101. Obtain the device status of an external storage device connected to the interface of the external storage device.

Specifically, the external storage device connected to the external storage device interface of the camera host is scanned to obtain the device status of the external storage device. The device status includes available status and unavailable status. Of course, it can also include other information, such as capacity, remaining capacity, read/write speed, interface type, and so on.

Exemplarily, acquiring the device status of an external storage device specifically includes: detecting whether an external storage device is connected; when detecting that an external storage device is connected, scanning the external storage device to determine the status of the external storage device; Whether the external storage device meets the recording requirements; if the external storage device meets the recording requirements, it is determined that the device status of the external storage device is available; if the external storage device does not meet the recording requirements, it is determined The device state of the external storage device is an unavailable state. In this way, the device status information of the external storage device can be determined when the device is connected, so that the user can understand the device status of the external storage device before the operation, and it is convenient for the user to perform surgery and video recording.

Specifically, the recording requirement may satisfy the condition of video recording, which may be set according to the needs of the external storage device for video recording. For example, the capacity must be greater than the preset capacity threshold, the read and write speed must meet the speed requirements, and so on. The device status of the external storage device that meets the recording requirements is determined as the available state, and the device status of the external storage device that does not meet the recording requirements is determined as the unavailable state.

If it is detected that at least two external storage devices are connected, one of the external storage devices can be scanned first to determine its device status; then the other external storage device can be scanned to determine its device status. Of course, you can also scan at the same time.

Exemplarily, determining whether the external storage device meets the recording requirements can be specifically: identifying the external storage device, and if the external storage device can be identified, then determining that the external storage device meets the recording requirements , If the external storage device cannot be identified, determine that the external storage device does not meet the recording requirements; or determine whether the external storage device has remaining storage capacity, if the external storage device has remaining storage capacity , It is determined that the external storage device meets the recording requirements, if the external storage device has no remaining storage capacity, it is determined that the external storage device does not meet the recording requirements; or the read and write speed of the external storage device is determined If the read and write speed of the external storage device is not less than the preset threshold, it is determined that the external storage device meets the recording requirements. If the read and write speed of the external storage device is less than the preset threshold, If the threshold is set, it is determined that the external storage device does not meet the recording requirements.

Correspondingly, if the external storage device can be identified, the remaining storage capacity is sufficient, and the reading and writing speed meets the requirements, it is determined that the external storage device meets the recording requirements. Of course, when judging whether the external storage device meets the recording requirements, in addition to identification, remaining storage capacity, and reading and writing speed, other conditions may also be included, which are not limited here.
