Ustps (UDP Speedy Transmission Protocol Secure) and USSH
Hi HN, Over the last few days I've been building USTPS (UDP Speedy Transmission Protocol Secure), an experimental encrypted transport protocol built on top of UDP. The primary goal of USTPS is low-latency video streaming. A server can take a video source and expose it through a USTPS endpoint, while Linux and Android (Termux) clients receive the stream and expose it locally to applications such as VLC, mpv, and FFmpeg. Although streaming is the main focus, USTPS is not limited to media delivery. It can also be used for other reliable encrypted UDP-based applications, which is why I built…

In plain words
USTPS is an experimental encrypted transport protocol built on UDP designed for low-latency video streaming. A server streams video through USTPS endpoints to Linux and Android clients, which expose the stream locally to applications like VLC, mpv, and FFmpeg. The protocol prioritizes speed by accepting unordered packets and recovering missing data through selective retransmission rather than requiring ordered delivery. USSH, built on USTPS, extends the protocol beyond media delivery to other reliable encrypted UDP applications.

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
