Something to share with you guys.
I was looking for a decent video player to play smooth 720p video, with supported formats like mkv, mp4, flv etc..
I came across the apps listed below and like to comment a bit of it.
Rockplayer 4/5
I use rockplayer for a week now, overall quite satisfied, not until I found that it doesn't playback some of my flv files which do not support hardware decoding. Try playing them with software decoding results in lagging and out of sync.. playing hd mp4 was great though.
another thing is I can't set screen brightness in rockplayer..
QQplayer 2/5
Slow in playing back flv and hd mp4.
Uninstall it the next minute.
flv player 2/5
Plays flv videos better than rockplayer, controls are extremely small.
Other video formats are supported. Performance is noticeably poorer.
vital player 5/5
Playback my flv videos flawlessly on first try. Then I try with the hd mp4 that I downloaded.
The result was disappointing one. Very lag in playing back hd videos.
I thought that I'm out of luck and just about to give up, I looked into the setting page and notice the "Hardware Codec First"
so I gave it a try, and guess what?
My hd videos now manage to play perfectly! No sound sync problem or experience any lags during the playback!
Give it a try!
Best media player for android!

thanks for sharing bro! downloaded vital player. not bad
