Want mplayer2 (the newer fork of mplayer) that uses ffmpeg goodness to play all the latest avi's with funky codecs and mp4 hidef goodness. Some Openindiana contributors are building a lot of friendly packages in the oi-sfe repo.
sudo pkg set-authority -O http://staticdev.uk.openindiana.org:10002 oi-sfe
sudo pkg refresh --full
sudo pkg install SFEmplayer2 SFEgccruntime
P.S. Need to manually install SFEgccruntime as it was a forgotten dependency - This will be fixed I have been informed.
P.P.S - ALSO I have only tested and is only expect to work on OI_148
