Video standards
The encoding of analogue TV and video signals varies in many different
The default is to use "PAL" parameters.

Preview
To get a rough preview of the menus, run "videolink --preview menu-url"
where menu-url is the URL or filename of the first page to show.
Currently videos cannot be displayed in this preview mode.

Processing
To create a DVD filesystem, run "videolink menu-url output-dir" where
By default, VideoLink now calls ffmpeg to generate MPEG-2 streams for
menus. If you want it to use mjpegtools as it previously did, you
-must add the option "--encoder mjpegtools". If you use mjpegtools
-1.6.2 or earlier you must instead use "--encoder mjpegtools-old".
-This is due to an incompatible change in the syntax of the ppmtoy4m
-command between versions 1.6.2 and 1.8.
+must add the option "--encoder mjpegtools".
If this is successful you can then use mkisofs to create a DVD image
from the output directory. Alternately you can write this directory
equal to 10% of the frame dimension on each side of the body; this
doesn't apply to the background.
-Prior to version 1.8, Mozilla may signal that a page is completely
-loaded before any background images are loaded and displayed. This
-can result in VideoLink converting the page without the background
-images. If VideoLink is built with an older version of Mozilla you
-can work around this by using absolutely-positioned "inline" images,
-since Mozilla will always wait for these to load.

DVD players do not have "back" buttons, so you should generally
provide links to "higher" menu pages. However, they do have a button
for returning to the top menu.
Bugs
----
-Under Mozilla 1.7, VideoLink sets the assumed screen resolution to
-40 dpi, which I reckon to be the average resolution of a standard
-definition TV display. This should mean that text with a font size
-expressed in millimetres or points will appear around the specified
-size. Unfortunately this setting has a different effect under
-Mozilla/XULRunner 1.8:
-
-Mozilla Assumed Requested Actual size
-version resolution size (pixels) (inches)
- (dpi)
-
- 1.7 default:96 20 px 20 0.5
- 1.7 default:96 36 pt 48 1.2
- 1.7 40 20 px 20 0.5
- 1.7 40 36 pt 20 0.5
- 1.8 default:96 20 px 20 0.5
- 1.8 default:96 36 pt 48 1.2
- 1.8 40 20 px 48 1.2
- 1.8 40 36 pt 48 1.2

-From version 0.10, until I have a proper solution, VideoLink will not
-set the assumed screen resolution under Mozilla 1.8. I must advise
-against using font sizes in millimetres or points since they will vary
-between browser versions.
+VideoLink should set the assumed screen resolution to 40 dpi, which I
+reckon to be the average resolution of a standard definition TV
+display. This would mean that text with a font size expressed in
+millimetres or points will appear around the specified size.
+Earlier versions of VideoLink did this when built to use Mozilla 1.7.
+Unfortunately the resolution setting in Mozilla 1.8 actually affects
+measurements in pixels and not measurements in millimetres or points!
+The assumed screen resolution is always 96 dpi.
+
+Please specify measurements such as font sizes in pixels because
+measurements in millimetres or points are liable to change if and when
+I can override the assumed screen resolution again.
