ORANGGILA  Nice Player

I've looking for ages for player like this

VLC can not show proper subtitle fonts in mkv files like in windows, but with this Mplayer i can watch my favorites tv shows at easy

JONATHAN GUBLER  Great to see this updated again - v11 is the only player with smooth 720p playback on my ancient Dual G5...  
(Version rev11)

NED SCOTT  MPlayer in general runs better on both my new Macbook Pro and my old G5 tower. MPlayer OSX Extended is the best way to use MPlayer. The GUI excellent.

THEFINALEOFSEEM  Excellent software. Simple yet effective. Seems to do better than Quicktime in many cases and is definitely better at decoding than VLC. All it needs is good, clean multithreaded FFMPEG decoding support (it's currently in there, but it's noted as buggy) and this will be the perfect media player. Keep up the good work!  
(Version rev11)

ROBOTANK  MPlayer OSX Extended seems very good overall, but I've never managed to get it to properly open a VIDEO_TS folder. With encrypted disks it fails to load at all, and with unencrypted disks, it displays the picture with errors (i.e. weird colours, broken picutre, etc.). All discs that have failed in MPlayer work in VLC and Apple DVD Player. Anyone else have more luck with this aspect of the app?

ILGAZ  I have the ancient version, the one built years ago and it can play h264 720P HDTV on a Mac Mini G4 1.42 Ghz. It is totally impossible using any player on that configuration. Even Apple's highly optimized h264 decoder fails.

Regardless of configuration you have, just try it once and you will be really surprised.

BTW, as you can notice, they didn't abandon 10.4 people too ;)

JICHI  MPlayer is good but hard to control; VLC is easy to control but inefficient in decoding and rendering. Hence MPlayer OSX Extended is the best for me, and just remind me of the KMPlayer in Windows.

I just visited the official MPlayer download page, but found "outdated" mark on the OSX 1.0rc2 version released on Feb, 2008. I really hope MPlayer and this OSX Extension will keep developing, and maybe one day will beat plex, vlc, qt and anyother player if new hard-coded support of h.264 for linux is also added to OSX version of MPlayer.

BTW, the compatible codecs for MPlayer and also MPlayer OSX Extended can be found here:

PARTHIBAN M  To keep it simple, this beats VLC for me. It is definitely more stable than VLC, which has gotten to be a little shaky in the recent revisions. MPlayer OSX Extended also plays my 720p and 1080p movies the smoothest. Quicktime 7 chokes on some 1080p movies, and VLC has screen corruption if the bitrate is too high. MPlayer, lags the least out of all the other players, and this is only for really high bitrate 1080p movies. For everything else, its smooth as butter. Another cool thing is how impressively fast you can scroll the timeline on 1080p videos. It's literally instantaneous, which is something that even VLC or Quicktime cannot accomplish even now. Overall, I set this as my default video player, and I don't know if it has hardware acceleration or not, but at times it does seem to do things (such as timeline scrolling) so smooth that it looks like it could be due to GPU support.

The only gripe I have with this is the UI buttons. They don't look like they're the proper rollover state. The UI looks fine when the player is not the active window, and the buttons fit with that state perfectly, but when it IS the active window, they look out of place. Here are two screenshots that show what I mean:

Inactive window with perfect looking UI:

Active window with awkward and out of place looking buttons (sharpness):

I hope the devs are able to fix this in the next release. But other than that, this is the best video player on the Mac. Highly recommended.

ST00P!D M0NK3Y  Woot! This latest release fixed some very annoying bugs from the last release. Thank you. Works great now. =)  
(Version rev10)

PEN_SQ  I'm just reviewing to join the small chorus of "thank yous"! MPlayer was the light of my life back when I ran Linux, and it was sad to see it's state when I switched to Mac. It's great see active development on this port again. MPlayer is still my rock against a sea of shifting formats, retarded encoders, and damaged files.

Right now, I have mpeg and flv bound to MPlayer, mkv bound to VLC (for superior h.264 threading), and juggle common avi's to whichever isn't busy.

One other thing I'd like to toss in - mplayer's filtering abilities are only scratched on in the GUI, and can really dance around other players. Start with typing "-vf pp=ci/ac -spuaa 4" in the advanced options.
