[vlc] own subtitle demux and transport stream

[Alex Frignani]

Hi,

Excuse me for english but i am italian. I have modify file
/modules/demux/subtitle.c for parsing normal text. I do this because i want
to insert a source program into transport stream.
I have tested file modified with .avi and .ogg and work in correct way. When
i try to load subtitle with .ts it doesn't work. I try with normal subtitle
file like .srt or .sub and and doesn't work. VLC doesn't play also audio and
video.

where is the problem? i think that file /modules/mux/mpeg/ts.c doesn't mux
correctly audio/video and subtitle.

There is any way to solve this problem?
