Hi,
I read one article from microsoft, i.e. https://docs.microsoft.com/en-us/azure/media-services/media-services-specifications-live-timed-metadata azure will put timed metadata into fmp4, and will support various formats of timed metadata. As mpegts demuxer/muxer in ffmpeg support id3 tag, does ffmpeg's mp4 support the feature? Thanks!
