Detailed Description

Autodesk Animator FLI/FLC Video Decoder by Mike Melanson (melan.nosp@m.son@.nosp@m.pcisy.nosp@m.s.ne.nosp@m.t) for more information on the .fli/.flc file format and all of its many variations, visit: http://www.compuphase.com/flic.htm

This decoder outputs PAL8/RGB555/RGB565/BGR24. To use this decoder, be sure that your demuxer sends the FLI file header to the decoder via the extradata chunk in AVCodecContext. The chunk should be 128 bytes large. The only exception is for FLI files from the game "Magic Carpet", in which the header is only 12 bytes.
