I don't think that's the case -- at least, what you say doesn't seem plausible. I ask: How would the player (MPV, VLC, PowerDVD) know that a run length of 25 on line 460 does not apply to 1920x1080? I mean, why would the player scale the subtitles... how would it know to scale the subtitles, eh? The answer would be to make JPGs of the subtitles and see. I wish I knew how to do that. --Mark. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
