Fixed
- Conversion failing with
ffmpeg exited with code 234/Subtitle encoding currently only possible from text to text or bitmap to bitmapon files with a multi-stream external sidecar subtitle (notably VobSub.idx/.subpairs carrying multiple language streams in one file). The cmd builder emitted-map 1:sto pull every sub stream from each external input but only set a codec for the first output sub-stream index per file — ffmpeg picked its matroska default (ass/ssa, a text codec) for the remaining streams and tried to encode dvdsub bitmap → ass text. Added a catch-all-c:s copyafter the per-stream specs so any unset external sub stream defaults to byte-copy; the per-stream specifiers above still win for the streams they name (webvtt → srt path preserved).
