Respectfully, libcaption is essentially a dead project. The main repo hasn't had a commit in seven years, there are numerous separate forks with fixes/improvements. The OBS project has its own repo with fixes they've made, and they are well aware of the problem (in fact the ticket includes some discussion I had with one of the developers). https://github.com/obsproject/obs-studio/issues/4006 Devin -- Devin Heitmueller, LTN Global Communications o: m: w: https://ltnglobal.com e: devin.heitmuel...@ltnglobal.com _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
