UsbWebCamera

UsbWebCamera is an application designed for Android devices that enables users to utilize UVC (USB Video Class) webcams as a video source. This app allows users to connect their external webcams via an OTG (On-The-Go) cable and access a range of features for both video capturing and image processing. Users can download UsbWebCamera to explore its various functionalities, which cater to different needs related to video streaming and recording.

The app supports capturing still images and videos, providing an intuitive interface for users to manage their capturing preferences. Users can save video files in MP4 format and still images in PNG format, storing them directly into designated folders on external storage. The application has a maximum duration limit of three minutes for video recordings in the free version, while a paid version offers unlimited recording time for those who require extended usage.

One notable aspect of UsbWebCamera is its capability to adjust various image settings, which can enhance the quality of the video feed. Users can modify parameters such as brightness, contrast, saturation, sharpness, gamma, gain, and white balance, provided their webcam supports these features. This level of customization allows for a tailored video output that can meet individual preferences or specific project requirements.

The app also includes a mirror display option, which enables users to flip the preview image horizontally, vertically, or both. This feature can be particularly useful for applications such as video conferencing or live streaming, where a mirrored image may be more visually appealing or easier to use. The flexibility of screen orientation is another useful feature; users can choose whether the app rotates with the device or maintains a fixed portrait or landscape view.

Additionally, UsbWebCamera incorporates an interval capturing function, allowing users to take a series of still images or videos at specified time intervals. This feature can be beneficial for time-lapse photography or monitoring activities over a period. Users can initiate this capturing mode through a long press of the capturing button, streamlining the process for those looking to capture multiple frames without manual intervention.

For users concerned about battery consumption, the app implements several features designed to minimize power use. These include limiting the maximum frames per second (FPS) during video preview, quality control measures for preview rendering, and automatic screen dimming. These adjustments help extend the device's battery life while still providing a functional video capturing experience.

UsbWebCamera has a straightforward user interface that facilitates easy navigation and functionality. Users can start and stop video recording or still image capturing with a single button press, making the app accessible for users of varying technical skill levels. The capturing button is prominently placed, ensuring that users can quickly access the main functions without navigating through complex menus.

The app operates without requiring root access or a custom ROM on Android devices, making it compatible with a broad range of phones and tablets. This ease of access is a significant advantage for users looking to enhance their video capturing capabilities without extensive technical modifications. Moreover, the app is designed to work with many generic UVC webcams and video grabbers, although it is important to note that not all devices may be compatible.

Users are advised to disconnect their webcams when not in use to conserve battery power, as simply connecting a webcam can draw significant current. For optimal performance, the use of a self-powered USB hub is recommended, especially for users with high-power webcams. It is also important to note that the app currently supports only one camera at a time, even if multiple cameras are connected through a USB hub.

Permissions required by the app include access to external storage for saving images and videos, network access for ad display, vibration feedback for capturing intervals, and audio recording capabilities. These permissions allow the app to function effectively while providing users with important feedback during their capturing sessions.

UsbWebCamera offers a comprehensive set of tools for users looking to utilize external webcams on their Android devices. With features that enhance video capturing, image customization, and battery efficiency, the app serves as a valuable resource for various applications, from casual photography to more professional video projects. Users interested in these functionalities can download UsbWebCamera and explore its capabilities in depth.
