There are public MPlayer development and user support mailing lists. Due to spam problems you can only post to our lists after subscribing. Unless explicitly stated otherwise the lists are English-only. There is a limit on message size, so you may have to put big files up for download somewhere instead of attaching them.
Before posting please learn and follow Netiquette as well as general rules about writing and quoting just as on usenet. For a complete refresher please read HOWTO Edit Messages or How do I quote correctly in Usenet?. As a guideline, remember that HTML mail, top-posting and thread hijacking (posting unrelated messages as replies to existing threads) are forbidden. Playing by the rules makes the life of those who read your mails a lot easier and significantly increases your chances of getting an answer.
This is the place to get support for problems related to usage, compilation and similar things. Please read all relevant parts of the documentation before posting your problems and feature requests.
The development mailing lists are for development related discussions and patches only! Usage-related questions, compilation troubles and similar things are offtopic and highly unwelcome. You have been warned.
There are two official channels on the Libera IRC network:
Developers with repository write access have operator status in #mplayerdev, contributors that have patches in MPlayer get voice. Nevertheless it is an open and unmoderated channel.
Note that the same topic restrictions apply that we have for the mailing lists. The development channel is for development-related discussions and questions only! Usage-related questions, compilation troubles and similar things are offtopic and highly unwelcome. You have been warned.
