        • FFmpeg is a free software project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the FFmpeg program itself, designed for command-line-based processing of video and audio files, and widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects, and standards compliance (SMPTE, ITU). FFmpeg includes libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and the core ffmpeg command line program for transcoding multimedia files.
        • FFmpeg is part of the workflow of hundreds of other software projects, and its libraries are a core part of software media players such as VLC, and has been included in core processing for YouTube and the iTunes inventory of files. Codecs for the encoding and/or decoding of most of all known audio and video file formats is included, making it highly useful for the transcoding of common and uncommon media files into a single common format.

Sorry, no clue what the other folks in this forum do.
Personally I would probably post in the ffmpeg developer mailing list and ask if there’s someone interested.
(I know that Fiona Glaser did consultant jobs a while back, but I’m not sure if she is still doing that. Side note: Don’t get confused DarkShakiri, Jason Garrett-Glaser, Fiona Glaser are all the same person.)

Dedicated to Fiona Glaser.

For the pretentious, Girls code and they do it well too.
