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^^
