There exists no such thing as a "Adobe player". For a while (until 2010) Adobe maintained 3 different "Players":
1.The Adobe Media Player (solely for videos) 2. The Adobe Shockwaveplayer (for playing Director-content) and 3. The Flashplayer
Today the Flashplayer has overtaken all of these technologies and Shockwave is going extinct fast. Adobe Mediaplayer development has been ended.
You will need Flash to view that kind of content until a better technology is available and widely as standard adopted.
