All you need to set up your stream is your PC and a web browser - preferably Chrome, Firefox, or Safari.
To transmit a stream, Video.Taxi accepts livestreams using the RTMP or HLS protocol as PUSH. Alternatively, you can also do an RTMP PULL.
The transformation from the video signal to stream is called encoding. For this, you can use a software encoder or a hardware encoder. Live streams are also possible with smartphone apps like "Larix" or "https://www.obsproject.com". Both are free of charge.
