An example of a successful fork: UMPlayer

A new version of UMPlayer 1.0 has been released

UMPlayer is a cross-platform multimedia player. There are currently versions for Linux, Windows and Mac Os.
UMPlayer is essentially a fork of SMplayer, and, like the parent, is also a frontend for Mplayer.
Some interesting under the cut.

The main features are the following features UMplayer:
- built-in support for codecs (270 pieces);
- plays Audio CDs, DVDs, (S) VCDs, TV / Radio cards, YouTube and SHOUTcast streams and incomplete or damaged multimedia files;
- well implemented search on Youtube and save videos;
- Support for virtually all keyboard shortcuts from Mplayer;
- support for subtitles (there is a function of their search);
- convenient video and audio equalizer;
- supports CSS skins, (in principle, this greatly simplifies the creation of an ideal interface)
The developers have already drawn some pretty good base skins.

Black skin

Gonzo skin

Mac skin

Modern skin

Vista skin

The default theme is somewhat similar to Media Player Classic, so I advise aesthetes
immediately change the skin.

I personally programulina caused positive emotions.
I am glad that good things continue to develop.
