Hi there, I am trying to find the documentation for a specific metadata tag: 'date'. According to the following page:
* https://wiki.multimedia.cx/index.php/FFmpeg_Metadata ffmpeg has a built-in mechanism for tag: 'title'. I also see that my ffmpeg version has the same property for tag 'date' but only for a round trip mp4 ⇔ avi. This property does not work with an mkv container. Is this pure luck that tag 'date' is transferred from avi to mp4 & mp4 to avi ? Should it work the same way for mkv container ?
