[MPlayer-dev-eng] [PATCHS] fix unsafe 'angle' and 'chapter' properties

[Mathieu SCHROETER]

Hello,

The properties 'chapter' and 'angle' are unsafe. For example:

  $mplayer -idle -slave
   get_property chapter
or
   get_property angle

returns a segv because mpctx->demuxer is NULL and not tested.


patch 01.a fix for property angle
       01.b cosmetic

patch 02.a fix for property chapter
       02.b cosmetic


Regards,
