Enemy Territory server side demos

This is a library for recording players from server.

Compatible with vanilla etded 2.60b linux-i386. Any mod should work as this is an engine extension.

Recorded demos are identical to standard client-side demos, so there's no need for a replay server or a patched client.

Installation

Build from source or download .so from releases.

The library needs to be preloaded into the etded binary, like this:

LD_PRELOAD=/path/to/libetwolf_server_demo.so etded +set dedicated 2 +...

Use absolute path for LD_PRELOAD.

Usage

Recording on demand:

record <clientNum>

Stopping the recording:

stoprecord <clientNum>

All demos will be written to %mod%/demos folder.
