libav has no video encoders?

I'm currently working on a screen recorder for the Jolla phone. For encoding the video I want to use avutils as it's already preinstalled on the phone but I'm stuck.

This is what my program currently outputs:

$ ./SailfishRecorder test.file
Cannot find h264 codec (check your libav installation)

The corresponding code is:

AVCodec *codec = avcodec_find_encoder(CODEC_ID_H264);
if(!codec)
{
    fprintf(stderr, "Cannot find h264 codec (check your libav installation)\n");
    close(fd);
    fclose(file);
    return 1;
}

So I checked libav:

$ avconv -codecs

What I get from there is that it only supports aac encoding which isn't helpful at all. Am I doing something wrong or is there any reason we don't have encoders? Any other library I could use to encode?
