However, due to the varying vendor-specific extensions employed by different camera models, acheving compatibility among them has been challenging. Tethr addreses this issue by acting as a bridge and offering a standarized and contemporary interface for developers. With Tethr, developers can interact with cameras seamlessly, abstracting away the underlying differences and complexities.
The project takes inspiration from libgphoto2 in its pursuit of providing a comprehensive camera control solution.
As mentioned, due to the vendor-specific extensions added to the PTP, comprehensive support for each camera model's features requires vendor-specific implementation. Without such support, the library can only access a limited set of configs exposed through standard device properties defined in the PTP specification. In addition, the library offers fallback functionality to web cameras in situations where WebUSB is disabled or when no USB-connected camera is detected.
This enables developers to seamlessly switch to using web cameras, such as those integrated into smartphones, as an alternative capture source. If you want to implement a support code for a new camera model, or ask someone for support instead, please refer to the contribution guide shown below.
The project is in the early stages of development and lacks complete documentation. Here is a code sample to provide you with an understanding of how to utilize the library. The configName mentioned in the subsequent sample code can be replaced with the names shown above. If you want to obtain information about a config, such as its writability and a list of valid values. Whenever a config is changed, a correspoinding configNameChange event will be fired.
