Transcribe Video

Extract transcript text from a local video file. The skill checks for embedded subtitles first (faster and more accurate), and only falls back to API-based speech recognition if none are found.

Step 1: Identify the video file

Confirm the video file path with the user. Supported formats: mp4, mkv, mov, avi, webm, and any format ffmpeg can handle.

Step 2: Check for embedded subtitles

ffprobe -v quiet -select_streams s -show_entries stream=index,codec_name:stream_tags=language,title -of json "<video_path>"

• If subtitle streams exist → go to Step 3a (extract embedded subtitles)
• If no subtitle streams → go to Step 3b (API transcription)
