Dear all, While updating Kodi to use the ffmpeg provided A53 side data for closed captions instead of our custom (old) demuxer (c.f. https://github.com/xbmc/xbmc/pull/22333) and running it against a battery of test samples I've found the following messages in the log for one particular sample:
[ffmpeg/video] h264: Late SEI is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. [ffmpeg/video] h264: If you want to help, upload a sample of this file to https://streams.videolan.org/upload/ and contact the ffmpeg-devel mailing list. (ffmpeg-devel@ffmpeg.org) This happens with ffmpeg version 5.1.2 and current master. To reproduce the problem you can simply open it with ffplay: ffplay https://livesim.dashif.org/dash/vod/testpic_2s/cea608.mpd The sample in question has two closed caption streams, although in ffmpeg none is detected/demuxed (a53 side data is empty). You can validate the proper behavior using dash.js for example: https://players.akamai.com/players/dashjs?streamUrl=https%3A%2F%2Flivesim.dashif.org%2Fdash%2Fvod%2Ftestpic_2s%2Fcea608.mpd Hope you find this helpful, Best regards, Miguel _______________________________________________ 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".
