 On removing the assignment operations in the declaration of the typedef
struct, all the errors were gone...now i'm doing those assignments in the
read_header()

:) It's a toggle switch, 0 indicates that audio has to be read and 1
indicates that video has to be read. Will change the  variable names to more
appropriate ones soon.

Right now, I'm getting a wierd error with the decoder part. In my demuxer,
the read_video() is mostly dummy as of now and the /libavcodec/bfi.c is
mostly dummy as well. But I've registered the decoder and put the
initialization of bfi_decoder as follows:
AVCodec bfi_decoder = {
        .name = "bfi",
        .type = CODEC_TYPE_VIDEO,
        .id = CODEC_ID_BFI,
        .priv_data_size = sizeof(BFIContext),
        .init = bfi_decode_init,
        .close = bfi_decode_close,
        .decode = bfi_decode_frame,
};

The error I'm getting is that :
In function `avcodec_register_all':
/libavcodec/allcodecs.c:69: undefined reference to `bfi_decoder'

Does this happen if the decoder is incomplete?
