[MPlayer-dev-eng] Logical bidi subtitles (fribidi)

[Amir Hardon]

Hi,
The current implementation of fribidi in mplayer tells fribidi to calculate 
the text direction, this is good, but for a perfect world.
The popular proprietary players are not calculating the text direction but 
assuming Left-To-Right, this caused most (if not all) of the existing 
subtitles files being written incorrectly in order to be showed correctly.

Making the same situation for Mplayer is easy and requires changing one line,
(For mplayer-1.0pre3try2 its line 1083 in subreader.c) from:
base = FRIBIDI_TYPE_ON;
to:
base = FRIBIDI_TYPE_LTR;

But a better solution would be adding a runtime option for choosing the 
direction(LTR, RTL, or auto). I am willing to implement this if someone can 
guide or point me to some documents about adding new arguments, and how to 
check for their values.
