dash demuxer cannot support rotation

[K.Y.H]

FFmpeg's dash demuxer is cannot transfer meta data..
So mp4's rotation information is cannot support.

libavformat/dashdec.c
static int open_demux_for_component(AVFormatContext *s, struct representation *pls)
{

int ret = 0;
int i;

pls->parent = s;
pls->cur_seq_no = calc_cur_seg_no(s, pls);

if (!pls->last_seq_no) {

pls->last_seq_no = calc_max_seg_no(pls, s->priv_data);

}

ret = reopen_demux_for_component(s, pls);
if (ret < 0) {

goto fail;

}
for (i = 0; i < pls->ctx->nb_streams; i++) {

AVStream *st = avformat_new_stream(s, NULL);
AVStream *ist = pls->ctx->streams[i];
if (!st) {

ret = AVERROR(ENOMEM);
goto fail;

}
st->id = i;
avcodec_parameters_copy(st->codecpar, ist->codecpar);
avpriv_set_pts_info(st, ist->pts_wrap_bits, ist->time_base.num, ist->time_base.den);

av_dict_copy(&st->metadata, ist->metadata, 0); added by K.Y.H

}

return 0;

fail:

return ret;

}

Please apply it
