This seems to be gated by FF_MOV_FLAG_RTP_HINT.

    if (mov->flags & FF_MOV_FLAG_RTP_HINT) {
        /* Add hint tracks for each audio and video stream */
        for (i = 0; i < s->nb_streams; i++) {
            AVStream *st = s->streams[i];
            if (st->codecpar->codec_type == AVMEDIA_TYPE_VIDEO ||
                st->codecpar->codec_type == AVMEDIA_TYPE_AUDIO) {
                mov->nb_streams++;
            }
        }
    }


However, I can't seem to disable it.  The original code did not pass
options to avformat_write_header() and didn't run into this.

Are the track hints supposed to be created by default?
