The use of multipath techniques in transmission has emerged in the last years thanks to their potential in increasing throughput. They can also be used as a means to counteract errors or losses in transmission, thus increasing reliability. In this work, we focus on the challenging scenario of real-time video streaming from an Unmanned Aerial Vehicle (UAV) via multiple wireless channels. We propose a lightweight scheduler capable of dynamically selecting the paths to be used and of determining the necessary redundancy rate to protect the multimedia flow. Our scheduler, implemented as a module of the GStreamer framework, can be used in real or simulated settings. The results we present show that the proposed scheduler can be used to target a very low loss rate by dynamically adapt to varying channel conditions in terms of losses and experienced delay.
