When it rains it pours. For the first two years of Google Android’s life there weren’t really any all purpose video players for the platform. The built in video player is bundled with Android’s picture viewer and only supports a handful of video formats. But recently RockPlayer launched an excellent video player with support for a wide range of formats including MKV, Xvid, WMV, and DiVX.
Today I ran across another Swiss army knife video player called arcMedia. It’s completely free — at least while in beta. It uses open source FFmpeg libraries and can handle a similar range of video formats including DiVX, Xvid, MOV, Mp4, WMV, and RMVB. The arcMedia video player supports all versions of Google Android.
