I wanted to play video content on my AmigaOne X1000 and found that the built-in DV Player Special Edition in AmigaOS4 is limited in what content it will play, and you have to pay extra for a full version that unlocks most of it's functionality.
Fortunately MPlayer is also available for AmigaOS4, it is free, and will play most video content formats I can throw at it like DIVX, AVI, XVID, MP4, and physical Dvd playback. But this program doesn't work out of the box on the X1000 and setting changes are needed before it works. I will show you what you need to do!
First, You need to download the MUI-MPlayer from OS4Depot.net. Just search for mui-mplayer.
Extract the archive somewhere on your system - I put it in Sys:Utilities/MPlayer. There are two versions of Mplayer included in the extracted archive, Altivec or generic. You can run either version but I recommend the Altivec version on the X1000.
When you first run Mplayer, you get the GUI and you will try to open your favourite video file. However, you will find that it does not play back video content or DVD content at all and just exits on trying to play anything.
To fix this, you need to run Mplayer again, select Settings menu, and then select Preferences. Then in the Preferences window, modify it so it looks like the below screenshot:
Basically we are changing the video display type to cgx_wpa and DVD device name to sb600sata.device:1, which works well with the X1000. Even though the DVD device field is greyed out, it can be modified as per the other fields.
After this you will find the videos will playback as expected, and DVD Playback will also work now.
Hopefully this helps some people out there who hit the same problem with MPlayer!
