if ((tag = av_metadata_get(st->metadata, "stereo_mode", NULL, 0)) ||
    (tag = av_metadata_get( s->metadata, "stereo_mode", NULL, 0)))

Will prefer stream metadata but can also use global metadata.
Of course the proper solution is to implement a way to specify
per-stream metadata on the command-line.
