Command
./build/krillinai-cli subtitle "<input>" \
--origin-lang en \

--workdir tasks/demo \
--caption-source any
Build the CLI first if needed:
go build -o build/krillinai-cli ./cmd/cli
Inputs
- YouTube URL: prefer
--caption-source any; platform captions are used first, then Whisper fallback. - Local file: use
local:/abs/path/video.mp4or a path accepted by the CLI. - Bilibili or other yt-dlp supported links: use when media download works; platform caption behavior may differ, so expect transcription fallback.
