Adding public API requires an minor version bump.

Also, I would simplify avcodec_type_string() using a table:

static const char *codec_type_string[] = {
    [CODEC_TYPE_VIDEO]    = "video",
    [CODEC_TYPE_AUDIO]    = "audio",
    [CODEC_TYPE_DATA]     = "data",
    [CODEC_TYPE_SUBTITLE] = "subtitle",
    [CODEC_TYPE_NB]       = "unknown",

char *avcodec_type_string (char *buf, int buf_size, enum CodecType codec_type)
    if (codec_type<0 || codec_type>CODEC_TYPE_NB)
        codec_type = CODEC_TYPE_NB;
    av_strlcpy(buf, codec_type_string[codec_type], buf_size);
    return buf;
