Fixed
- Conversion of a video-only source (no audio stream) failed with exit 234 (
Stream map '0:a' matches no streams). Files with only video + subtitles — a video-only Blu-ray remux, or a sample clip — hit the default-map 0:awhich ffmpeg treats as fatal when nothing matches. Changed to-map 0:a?(optional map) in both the main convert path and the subtitle-prestrip pass.
