still happening in 7041…
I narrowed down the issue: SF seems to mix in the subtitles into the MP4 with ffmpeg and then extract the subtitles from the resulting MP4 into srt (while pretending they are WebVTT) using CCExtractor.
Naturally, once you mux in WebVTT into MP4 using mov_text, you lose all WebVTT extras, so the resuling files aren’t WebVTT even if you tell CCExtractor to extract them as WebVTT but are plain SRT:
Could you ask the dev to look into that, as double work seems rather unnecessary and ruins perfectly good WebVTT, @Wilson.Wang ?
