// Generated from an ffmpeg command by the ez-ffmpeg CLI-compat emitter.
// command: ffmpeg -i in.mp4 -vf scale=1280:-2 -c:v libx264 -crf 23 -preset fast -c:a aac -y scaled.mp4
// dialect: ffmpeg 7.1 command line; manifest: r4; crate: ez-ffmpeg 0.15.0; cargo features: none required
// status: verified shape V5 (scaled H.264/AAC transcode (-vf scale)) — verified by the manifest-driven semantic golden suite (oracle: Scale) against the ffmpeg CLI; canonical emission compile-pinned as examples/cli_emitted_scale.rs
// precondition: -vf requires the input to contain exactly ONE video stream;
// in-process execution enforces this after probing (see from_cli_args), and
// this generated code inherits the same assumption.
