libOBS Sources

This crate makes it really easy to create new sources for OBS Studio using the libobs-wrapper crate.

(This example is outdated, look at tests and examples for more up to date code)

Example

let rec_file = ObsPath::from_relative("monitor_capture.mp4").build();
let path_out = PathBuf::from(rec_file.to_string());

// Start the OBS context
let startup_info = StartupInfo::default();

// You can also create use a logger to log to a file
// let _l = DebugLogger { f: File::create(current_dir().unwrap().join("obs.log")).unwrap() };
// startup_info = startup_info.set_logger(Box::new(_l));

let mut context = ObsContext::new(startup_info).unwrap();

// Set up output to ./recording.mp4
let mut output_settings = ObsData::new();
output_settings.set_string("path", rec_file);

let output_name = "output";
let output_info = OutputInfo::new("ffmpeg_muxer", output_name, Some(output_settings), None);

let mut output = context.output(output_info).unwrap();

// Register the video encoder
let mut video_settings = ObsData::new();
video_settings
    .set_int("bf", 0)
    .set_bool("psycho_aq", true)
    .set_bool("lookahead", true)
    .set_string("profile", "high")
    .set_string("preset", "fast")
    .set_string("rate_control", "cbr")
    .set_int("bitrate", 10000);

let encoders = ObsContext::get_available_video_encoders();

println!("Available encoders: {:?}", encoders);
let encoder =  encoders.iter().find(|e| **e == ObsVideoEncoderType::H264_TEXTURE_AMF || **e == ObsVideoEncoderType::AV1_TEXTURE_AMF).unwrap();

println!("Using encoder {:?}", encoder);
let video_info = VideoEncoderInfo::new(
    encoder.clone(),
    "video_encoder",
    Some(video_settings),
    None,
);

let video_handler = ObsContext::get_video_ptr().unwrap();
output.video_encoder(video_info, video_handler).unwrap();

// Register the audio encoder
let mut audio_settings = ObsData::new();
audio_settings.set_int("bitrate", 160);

let audio_info =
    AudioEncoderInfo::new("ffmpeg_aac", "audio_encoder", Some(audio_settings), None);

let audio_handler = ObsContext::get_audio_ptr().unwrap();
output.audio_encoder(audio_info, 0, audio_handler).unwrap();
let mut scene = context.scene("main");

let monitor = MonitorCaptureSourceBuilder::get_monitors().unwrap()[1].clone();
println!("Using monitor {:?}", monitor);
let mut capture_source = MonitorCaptureSourceBuilder::new("monitor_test")
    .set_monitor(&monitor)
    .add_to_scene(&mut scene)
    .unwrap();

scene.add_and_set(0);
output.start().unwrap();

println!("Recording started");
std::thread::sleep(Duration::from_secs(5));
println!("Recording stop");

output.stop().unwrap();
// And now your monitor is recorded to ./recording.mp4 !
