Am I missing somethin here or is the value at linebufpos being set to 0
just after it has incremented and given a value?
Is C/C++ doing the assigning before the incrementing? That would make
this make sense (from NuppelVideoRecorder.cpp):
if (!visible)
{
st.row = y;
st.col = x;
st.dbl = dbl;
st.fg = fg;
st.bg = bg;
linebufpos = linebuf;
*linebufpos = 0;
}
*linebufpos++ = c;
*linebufpos = 0;
visible = 1;
I have done a few experiments and it seems the data is read, but are
they written? I can't seem to figure that out...
Attached is an example from a late night BBC Prime broadcast with
several subtitle streams. I am dumping all characters, running it
through uniq to minimize empty lines...
I have also checked one of the shows I recorded with teletext grabbing
enabled. The text is in there, but it is not shown on my screen?!

I guess I need to look at the non-ascii characters and do a Unicode
convertion on the finished string, if only I could figure out how to get
said string...
