Crate ffai_media 

ffai-media

Media ingest/egress for FFai — the libavformat seat.

Policy: all container/codec work routes through remade_ffmpeg_rs (rff-* crates) as the default backend — we own it, it is pure Rust, and it keeps the zero-C/C++ promise. Phase 0 ships native WAV support (the one format every ASR/TTS engine needs on day one); everything else returns a clear “pending rff integration” error rather than silently failing.

Modules

annexb

AVCC (length-prefixed) H.264 to Annex-B (start-code prefixed).

Structs

VideoStream

Sample frames from a video at fps frames/second (for Argus video understanding). Pending the rff demux/decode integration. A lazily-decoded video, yielding one frame at a time.

Functions

load_audio

Load an audio file into a normalized f32 AudioBuffer.

load_image

Decode a still image — PNG and JPEG today; WebP/AVIF/GIF follow.

sample_frames

Every frame at once. Prefer stream_frames — this holds the whole video in memory and exists for callers that genuinely want a Vec.

save_gray16_png

Write a 16-bit grayscale PNG.

save_wav

Write an AudioBuffer as 32-bit float WAV.

stream_frames

Open a video and stream its frames. fps <= 0 keeps every frame.
