I hacked unconditional timecode output some time ago not sure how useful it

I guess other metadata will require some gui changes. Cinelerra - CVE  had
something like this... (if I remember correctly)



// Metadata
  AVDictionary *meta = 0;
  struct tm ctim, *ptm;
  time_t tst;
  char string[128];

  av_dict_set(&meta, "comment", version_name, 0);
  tst = time(0);
  if((ptm = gmtime_r(&tst, &ctim)) &&
    strftime(string, sizeof(string), "%FT%TZ", ptm))
   av_dict_set(&meta, "creation_time", string, 0);

  if(metalist = asset->encoder_parameters[FILEAVLIBS_METADT_IX])
   if(aparam = metalist->find("copyright"))
    av_dict_set(&meta, "copyright",
     aparam->stringvalue, 0);
   if(aparam = metalist->find("title"))
    av_dict_set(&meta, "title",
     aparam->stringvalue, 0);
   if(aparam = metalist->find("author"))
    av_dict_set(&meta, "author",
     aparam->stringvalue, 0);
  context->metadata = meta;
