FreeRearviewCam 1.0

The FreeRearviewCam application offers an innovative solution for creating a rearview camera system utilizing two smartphones at no cost. The current smartphone acts as the monitor for the driver, while an older, unused smartphone is positioned at the rear of the vehicle, leveraging its camera capabilities. The app seamlessly connects both devices, transforming them into a functional rearview camera.

For users seeking an ad-free experience along with additional features like recording functionality, an Advanced version is available for a nominal fee. Furthermore, a Pro version is anticipated in the future, promising enhanced features.

It is important to note that video transmission can be battery-intensive, particularly for the smartphone serving as the camera. Users planning to employ this setup for extended periods should ensure that they keep the camera phone connected to a power source and consider powering it down after usage.

Attention SAMSUNG users: The compatibility of FreeRearviewCam with Samsung devices is somewhat limited. Due to their unique implementation of Android guidelines, each connection between the sending and receiving smartphones necessitates a revalidation on the sender's device. This process may involve additional steps for users, particularly if the sending device is mounted at the rear of the vehicle. Given this limitation, it is advisable to carefully consider this app's use with Samsung products.

Regarding technical aspects, FreeRearviewCam utilizes FFmpeg for video processing by calling a precompiled FFmpeg binary as an external process. Detailed information about the source code used for compiling FFmpeg can be found at this link.
