Please reconsider an abandoned patch to allow consistent behavior in closed caption detection between ffprobe with and without "-print_format json". https://patchwork.ffmpeg.org/project/ffmpeg/patch/mn2pr04mb59815313285aa685e37d09aeba...@mn2pr04mb5981.namprd04.prod.outlook.com/
I also asked for solutions on reddit, videohelp, IRC, ffmpeg-user, resorting to asking on ffmpeg-devel. I would like to add the ability to detect and remove closed captions from video streams using ffmpeg, in an open source tool I maintain that cleans up media files for direct play on Plex, Emby, Jellyfin, etc. ( https://github.com/ptr727/PlexCleaner) When I run ffprobe in JSON output mode, it is not setting the "closed_captions" attribute. When I run ffprobe in default output mode, it does correctly identify closed captions in video streams and prints "Closed Captions" in the stream descriptor. The divergent behavior appears to be a ffprobe bug. Details of the problem is described where I asked for help on reddit and videohelp: https://www.reddit.com/r/ffmpeg/comments/tcnhto/how_to_detect_closed_captions_in_video_stream/ https://forum.videohelp.com/threads/405123-Detect-embedded-closed-captions-in-video-stream-using-ffprobe-json-output I did not get any help, but after lots of googling I did find an abandoned patch that describes exactly the problem I am experiencing: https://patchwork.ffmpeg.org/project/ffmpeg/patch/mn2pr04mb59815313285aa685e37d09aeba...@mn2pr04mb5981.namprd04.prod.outlook.com/ https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=&submitter=&state=*&q=closed_captions&archive=both&delegate= https://www.mail-archive.com/ffmpeg-devel@ffmpeg.org/msg126211.html The proposed patch seemed trivial, but I do not understand the nuances of the objections. I'd like the patch to be please re-considered, or an alternative proposed that allows ffprobe's JSON output to return correct closed_captions values. --- Pieter _______________________________________________ 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".
