fluvie_mobile_encoder 0.2.0

Render Fluvie videos to MP4 fully on-device on Android and iOS using the platform's native hardware encoder, with no FFmpeg and no server.

example/main.dart

/// Renders a two-second clip fully on-device, no FFmpeg and no server.
///
/// Runs on Android and iOS: Fluvie's own pipeline captures the frames and the
/// platform's native encoder writes the MP4, so the video never leaves the
/// device. For a complete app on this path, see the repository's
/// `examples/mobile_purrfect`.
