Hello, I'm trying to figure out if FFmpeg or the underlying subtitle rendering library supports BT.709 color space for hardcoding subtitles. I've posted the question with extensive details (with example files on Google Drive) on superuser:
https://superuser.com/questions/1757284/ffmpeg-incorrect-colourspace-with-hardcoded-subtitles According to this answer (https://superuser.com/a/1757297/867738), it is deduced that FFmpeg uses BT.601 as standard for subtitles. This would explain the issues when videos with subtitles tuned for BT.709 are rendered with incorrect colors. The workaround to scale the color matrices works but is really bad on performance. Is this an issue related to FFmpeg which incorrectly determines the colorspace used for rendering the subtitles? Or is this something that has never been implemented?
