A recorder for Counter-Strike 2. Supports Linux on AMD64.

Build

Requirements:

• Python 3
• GCC (For Linux users)
• ambuild

Beforehand, ensure all your git submodules are up-to-date:

git submodule update --init --recursive

Then you can proceed to build:

mkdir build # Make build folder
cd build
python3 ../configure.py --sdks=cs2
ambuild .

Usage

First, install the mod by copying the addons folder into your game. For Linux users, the command may look like this:

cp -r package/addons/ ~/.local/share/Steam/steamapps/common/Counter-Strike\ Global\ Offensive/game/csgo

Next, Linux users must host the local command server. It is located here in the build folder:

cmdserver/linux-x86_64/cmdserver

This local server will receive and execute commands sent by cs2rec. It will primarily spawn background FFmpeg processes.

Finally, use the in-game console commands Example:

// The following command spawns FFmpeg in the background.
// You can run this many times to spawn many processes.
// The variables {{stdargs}} and {{video_input}} will be expanded.
sf_ffmpeg_start ffmpeg {{stdargs}} -y -loglevel warning -c:v rawvideo -f rawvideo -pix_fmt rgb0 -s:v 1920x1080 -framerate 60 -i {{video_input}} -c:v huffyuv output.avi

// Start in-game recorder.
// You MUST include TGA, which is hooked by cs2rec.
// "wav" will output a separate "mymovie.wav" file in the CS2 movie dir.
startmovie mymovie tga wav

// Stop in-game recorder
endmovie

// Stop the spawned FFmpeg processes to finalize the video output
sf_ffmpeg_stop

That is all.

FFmpeg must have every detail manually supplied. This includes:

• Pixel format (-pixfmt <fmt>, commonly rgb0)
• Resolution (-s:v <width>x<height>)
• Framerate (-framerate <fps>)

This is because cs2rec does not know which resolution and framerate will be used with startmovie.
