[Ffmpeg-devel] Including a new codec problem

[Eduardo Morras]

Hello:

   I'm making a video codec in ffmpeg. Eveything compiled fine but last weekend i delete and rebuild all ffmpeg source tree from svn and add the codec to it. I follow the instructions on http://wiki.multimedia.cx/index.php?title=FFmpeg_codec_howto but can't compile the codec.


a) add the codec id in avcodec.h ( CODEC_ID_GOG, )
b) registered the decoder and encoder in allcodecs.c (REGISTER_ENCDEC(GOG, gog) 
c) add in riff.c { CODEC_ID_GOG, MKTAG('G', 'O', 'G', ' ') },     last '' is 'space'

In gog.c i have the next AVCodec definition (copied from snow and changed snow by gog):

AVCodec gog_decoder = {
    "gog",
    CODEC_TYPE_VIDEO,
    CODEC_ID_GOG,
    sizeof(GogContext),
    decode_init,
    NULL,
    decode_end,
    decode_frame,
    0  /*CODEC_CAP_DR1*/ /*| CODEC_CAP_DRAW_HORIZ_BAND*/,
    NULL
};

#ifdef CONFIG_ENCODERS

AVCodec gog_encoder = {
    "gog",
    CODEC_TYPE_VIDEO,
    CODEC_ID_GOG,
    sizeof(GogContext),
    encode_init,
    encode_frame,
    encode_end,
};

#endif //CONFIG_ENCODERS

 Am i missing something? Register it somewhere else? Before the rebuild i can compile ffmpeg with it and now i get next errors:
