This article will guide you through converting an audio RTP stream to a local audio file format using FFmpeg, specifically targeting ADB RX90/91 devices.
What is RTP?
Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. It's commonly used in VoIP (Voice over IP) systems and multimedia applications to provide real-time data transmission.
Introduction to FFmpeg
FFmpeg is a free and open-source software project that produces libraries and programs for handling multimedia data. It is primarily used for transcoding, streaming, and playing various multimedia formats.
