| AVCodec | ff_flic_decoder |
This decoder outputs PAL8/RGB555/RGB565 and maybe one day RGB24 colorspace data, depending on the FLC. 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.
