I am in the mid of developing a personal project which involves cameras and videostreaming.
While working on this project, I built a small port of the HTTP streaming server of Sebastian Dröge from C into rust:
clynamen/basic_http_webm_server_rust
The server uses a minimal tokio server and the gstreamer-rs library (of which the same S. Dröge is the main contributor).
The main difference between the two version consists in the absence of the multisocketsink element, which is not currently available on rust. This element allows to connect multiple TCP sockets to the gstreamer pipeline, thus providing a simple way for sending the video to multiple clients. In the rust version, this is replaced (probably in a bad way) by an appsink and multiple mpsc queues.
