SUP file format info?

[Dan203]

Does anyone have any technical info on the SUP file format? Or can anyone just explain to me the structure of the file? I'm looking to add SUP file format support to an application I'm working on but I can't find any technical info on the file format. Currenty the program already support SPC files, which are basically just elementary streams of the subtitle packets. However looking at a SUP file generated by VOBEdit it doesn't appear to be the same format, and when I run it through BBInfo it says that it's actually an MPEG-2 Transport Stream. Could that be the case? Are SUP files really just transport streams?

Hi!

The following MAY provide some help:

http://www.fileinfo.net/extension/sup

(There are links on the page as well)


Additionally, the following posting by the author of "srt2sup" appears to confirm your speculation:

http://209.85.173.104/search?q=cache:f0_qx5Y_A2UJ:forum.doom9.org/archive/index.php/t-65353.html+%22SUP%22+and+%22subtitle%22+and+%22description%22+and+%22format%22&hl=en&ct=clnk&cd=9&gl=us

The other problem is that SUP is a stripped down VOB which is an MPEG stream and the information on MPEG is strictly controlled >:-(

Maybe reading the DVDSubEdit source code (http://download.videohelp.com/DVDSubEdit/) will put you on the right path.

You can also have a look at SubtitleCreator's C# source code.
