Mailing lists
Please follow the netiquette when posting on FFmpeg mailing lists, especially avoid top-posting and thread hijacking (that is, replying to a thread and changing the subject line to something completely unrelated that was not being discussed within the original thread). Configuring your mail client to break lines after 70 or so characters is a plus. If you attach files, avoid compressing small files, uncompressed is preferred. Also please try to avoid posting mails with overly long signatures or nonsense corporate disclaimers that claim the content of your mails is confidential.
Attached patches should not have application/octet-stream as mime-type, but
text/plain or even better text/x-diff or text/x-patch.
If you send us a patch, please make it some form of unified diff. We prefer
patches made using git format-patch from the root of your FFmpeg
checkout or sent with git send-email. For more detailed
guidelines, have a look at the
MPlayer patch guidelines
most of what is written there applies to FFmpeg as well.
Trespass these rules at the risk of being flamed.

IRC channels
FFmpeg has two official channels on the freenode IRC network. Both channels are open and unmoderated. Developers with commit rights have operator status, contributors with patches in FFmpeg have voice in the channels.
#ffmpeg is for user support and general questions similar to the ffmpeg-user mailing list.
#ffmpeg-devel is strictly dedicated to FFmpeg development. This means development of FFmpeg itself. Development of other software that uses the FFmpeg libraries is offtopic there.
