Bug#885773: mpv: using dvd://<title> or dvdnav://<title> still plays longest title

[Kurt]

Package: mpv
Version: 0.23.0-2+b2
Severity: normal

Dear Maintainer,

when using mpv playing a selected title of a DVD, mpv does not play the
selected title but the longest title, for example:
"mpv dvd://4" acts equal to using "mpv dvd://"

With "dvdread://<title>" there is no problem.

I would suggest fixing this problem as follows:
- in file mpv_0.23.0/stream/stream_dvdnav.c in line 534
  replace line
     priv->title = bstrtoll(title, &rest, 10);
  with line
     priv->track = priv->title = bstrtoll(title, &rest, 10);

because in open_s() priv->track is set to default value TITLE_LONGEST,
but is not set when using a selected title, but is later used in open_s_internal().

Best regards,

Kurt
