I'm a software development and newbie in audio engineering topics. I ran Icecast audio stream server and would like to show cover art audio tag to website users. Stream format is Ogg. The problem is - cover tag doesn't display, but I'm sure, that the tag exists in Ogg audio file.
- Are there "public" and "private" audio metadata? If it's true, how can I identify which is which?
- What is the Ogg "encapsulated audio"? Shall I convert somehow normal Ogg file to this format to provide cover art tag to an software?
I didn't find answers on these questions in internet.
