STMCAM turns your smartphone into a professional-grade camera for live streaming and video capture. It supports both RTMP and SRT (MPEG-TS) streaming protocols, allowing you to send video directly to major platforms such as YouTube Live, Twitch, and Niconico Live. With SRT support, you can achieve stable streaming even in unstable network conditions. From manual controls like ISO, shutter speed, and white balance, to composition aids such as a level indicator and rule-of-thirds grid, as well as streaming history and bookmarks, STMCAM provides a complete set of tools for on-site production. Key Features ● Live Streaming (RTMP / SRT) Start streaming by simply specifying the host and port. Streams H.264 video and AAC audio in real time. ● Streaming History & Bookmarks Connection settings (protocol / host / port / app / stream key / stream ID) are automatically saved when you start streaming. Restore past settings with a single tap, or save them as named bookmarks for quick access. ● Video Recording Record high-quality video directly to your device’s photo library. Displays remaining recording time and available storage during recording, and automatically stops when storage runs out. ● Manual Exposure (ISO / Shutter Speed) Switch between auto and manual exposure. Independently adjust ISO and shutter speed in standard increments, suitable for low-light scenes, fast-moving subjects, and fixed exposure recording. ● White Balance Control Choose from auto, five presets (daylight, cloudy, shade, fluorescent, tungsten), or custom measurement. For custom mode, simply align the target frame at the center of the screen with your subject to lock the color temperature. ● Focus Control Switch between autofocus and manual focus. When switching from AF to MF, the current focus distance is preserved, allowing you to lock focus without altering composition. ● Composition Guides Overlay a rule-of-thirds grid and level indicator on the preview. Achieves horizontal alignment within ±0.5°, with visual feedback turning green. ● Zoom / Exposure Compensation Adjust seamlessly during both recording and live streaming. ● Audio On/Off Independently control audio recording for streaming and video capture. ● Portrait & Landscape Support Supports streaming and recording in all orientations, including portrait and both landscape directions. Recommended For * Users who want to live stream easily with just a smartphone * Creators who need SRT protocol support * Those streaming from outdoor or on-location environments * Users who want full manual control over ISO, shutter speed, and white balance * Those streaming within a local network, such as to a LAN server or OBS in offline environments
