C doesn't have member functions, only pointers to functions. Each codec
defines a AVCodec and sets its pointers to functions declared in the code
for that codec.
For example:
libavcodec/h263dec.c line 728
AVCodec h263_decoder = {
"h263",
CODEC_TYPE_VIDEO,
CODEC_ID_H263,
sizeof(MpegEncContext),
ff_h263_decode_init,
NULL,
ff_h263_decode_end,
ff_h263_decode_frame,
CODEC_CAP_DRAW_HORIZ_BAND | CODEC_CAP_DR1 | CODEC_CAP_TRUNCATED |
CODEC_CAP_DELAY,
.flush= ff_mpeg_flush,
};
libavcodec/mpegvideo_enc.c line 3738
AVCodec h263_encoder = {
"h263",
CODEC_TYPE_VIDEO,
CODEC_ID_H263,
sizeof(MpegEncContext),
MPV_encode_init,
MPV_encode_picture,
MPV_encode_end,
.pix_fmts= (enum PixelFormat[]){PIX_FMT_YUV420P, -1},
};
