The main excuse for removing this is that LIVE555 deprecated the API the mplayer implementation was using. The old API still seems to be somewhat supported, but must be explicitly enabled at LIVE555 compilation, so mplayer won't always work on any user installation. The implementation was also very messy, in C++, and FFmpeg support is available as alternative. Remove it completely.
