[Ffmpeg-devel] [RFC]: vhook Documentation

[Víctor Paesa]

Hi,

I agree on Diego's comments, except on this:

I'd rather point to some URL, it may change but docs may be updated too.

(notice that Diego is the official maintainer, so you'd better follow his
advice than mine :-)  )

I just tried the examples, and this one does not work on my computer:

+   # Scrolling credits from a text file
+   ffmpeg -i input.avi -vhook 'vhook/imlib2.so -c white -F
/usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/16 \
+     -x 100 -y -1.0*N -f credits.txt' -sameq output.avi

The reason is that my bash (3.2.9) doesn't understand the backslash
in the middle of single quoted strings, it does accept it if double
quoted, though.

Another comment is that you may reduce the command length, instead of
-F /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/16
your may use
-F VeraBd.ttf/16
if you set the FONTPATH.

Other than that, it looks ok.

Regards,
V?ctor
