ASS/SSA to BluRay SUP/PGS and BDN XML
---------------------------------

This program can be used to transform ass or ssa subtitles to BDN XML+PNG format.
This in turn can be transformed into a SUP file, which can be used to master a
BluRay disc with subtitles.

Usage instructions:

0. If you want to build it:
     cmake -Bbuild -DCMAKE_BUILD_TYPE=Release .
     cmake --build build

1. Prepare subtitles. You can either produce subtitles in a normal format like
   ASS/SSA.

2. Run the program:
     ass2bdnxml  -v 1080p -f 23.976 -o output.xml input.ass

3. For some programs, you have to convert the PNG files to 8bit RGBA palette.
   This doesn't apply to BDSupEdit. You can do it with a tool like pngquant or
   pngnq.

     pngnq:    http://pngnq.sourceforge.net/

4. You get a BDN XML file in the following format:

     <?xml version="1.0" encoding="UTF-8"?>
     <BDN Version="0.93" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:noNamespaceSchemaLocation="BD-03-006-0093b BDN File Format.xsd">
     <Description>
     <Name Title="Undefined" Content=""/>
     <Language Code="und"/>
     <Format VideoFormat="[ 480i / 480p / 576i / 720p / 1080i /1080p ]" FrameRate="[ 23.976 / 24 / 25 / 29.97 / 50 / 59.94 ]" DropFrame="false"/>
     <Events LastEventOutTC="00:00:00:00" FirstEventInTC="00:00:00:00" ContentInTC="00:00:00:00" 
     ContentOutTC="00:00:00:00" NumberofEvents="[ number of encoded frames ]" Type="Graphic"/>
     </Description>
     <Events>
     <Event Forced="[ False / True ]" InTC="00:00:00:00" OutTC="00:00:00:00">
     <Graphic Width="0" Height="0" X="0" Y="0">000000.png</Graphic>
     </Event>
     </Events>
     </BDN>

5. Use a program like BDSupEdit or BDSup2Sub to convert the BDN XML
   to a BD-SUP file. The rest is left as an exercise for the reader.
