The VLC media player is a free, open-source multimedia player produced by the VideoLAN corporation. It can play many audio-visual file formats including AVIs, MPEGs and WMVs, as well as DVDs and CDs, and handle most codecs without any separate codec packs. You can perform minor adjustments on files such as cropping, de-interlacing or sound magnification, and can stream media. You can add visualisation effects to when playing music. If your media plays too quickly or slowly, you can adjust its frame rate.
