Larix Broadcaster is a professional streaming application that allows users to stream high-quality video and audio content in real-time from their mobile devices. With a range of advanced features and support for various protocols, Larix Broadcaster is a reliable solution for remote contribution.

• SRT streaming in Caller (Push), Listen, and Rendezvous mode, powered by libsrt version 1.5.3.
• RTMP and RTSP streaming with SSL encryption for secure RTMPS/RTSPS transmission.
• WebRTC support via WHIP signaling.

One noteworthy feature of Larix Broadcaster is its ability to handle multiple simultaneous connections, enabling users to add several connection profiles and choose any of them for parallel streaming. Additionally, users can pause the stream without disconnecting it by long-tapping on the Start button. This feature is particularly useful as the video track will display a black screen and the audio track will only contain silence.

Another useful feature is the stand-by stream mode, which allows users to start a stream in pause mode with a separate set of overlays. This provides flexibility in creating customized streams with overlays tailored to specific requirements.

The application also includes talkback functionality, enabling users to receive audio return feeds via SRT, RTMP, Icecast, and SLDP protocols. This is particularly useful for scenarios where two-way communication is necessary.

Larix Broadcaster supports UltraHD resolution and Dolby Vision HDR, ensuring high-quality video output. It also provides support for both front and back cameras, offering a seamless experience for users.

The application also supports dual/triple camera systems, including wide-angle and telephoto cameras. This provides users with additional flexibility in capturing different perspectives during live streaming.

Center stage functionality is available for iPads, further enhancing the user experience. It can be enabled following the instructions provided by Apple.

Other notable features of Larix Broadcaster include autoexposure lock, white balance lock, manual color temperature adjustment, saving to MP4 format, screenshots, iCloud support, and the ability to record with different parameters such as larger resolutions.

For audio capabilities, Larix Broadcaster offers input audio gain control, source selection, and Bluetooth audio support. Users can also leverage the application's audio-only capture feature, which allows for streaming without video output. Additionally, pinch-to-zoom functionality is available, utilizing all iPhone 11 cameras.

Larix Broadcaster features H.264 encoding for all protocols, including WebRTC. It also supports HEVC/H.265 encoding for SRT, RTMP, RIST, and RTSP protocols. AAC audio is supported by default, except for WebRTC which uses Opus audio.

The application supports inserting SEI metadata into SRT, WebRTC, and RTMP streams for NTP synchronization via the Advanced menu.
