#1 Burning Software

Hi there,

Could I ask a question about StarBurn_ISO9660JolietFileTree_AddW? I encounter two problems when I try to use this function:

1. It returns error 5 if p__PWCHAR__RootDirectoryOrFileAbsolutePathAndName actually contains any non-ANSI characters (and reports a WIN32 error code of 123). My understanding is that filenames are (or can be) stored on Joliet discs as Unicode so why should this be?

2. The p__PWCHAR__RootDirectoryOrFileNewName parameter seems to be ignored. Files on the CD end up with the same names as the input files, which is not what I want. Calling StarBurn_ISO9660JolietFileTree_Add (without the W) works correctly. I am passing a filename, rather than a directory name, as input.

So it seems like AddW is broken, which is a shame as I would like to get Unicode filenames onto my Joliet CDs. Or am I missing something?

[Edit]
It's the Unicode *input* filename it's objecting to. The exception text reads:

CStarBurn_DiskFile::CStarBurn_DiskFile(): CreateFile( 'g:\temp\playtime\My Collection\A-ha - Stay On These Roads\01 - ?-ho! - Stay On These Roads.mp3' ) failed, status 123!!!

The '?' in the filename was passed in as a valid Unicode character. Looks like youse guys are converting the filename to ANSI before trying to open it, which is a problem for people trying to burn such a file (which is a perfectly valid file as far as Windows is concerned) to CD.

Tested on Tomohawk, 20081220.

OK, found a fix for this one: pass the source filename through GetShortPathName (). That seems to work. Still can't get a Unicode name onto the CD though.

[/Edit]

[Edit 2]
IMAPI (on Windows XP) can handle the Unicode filename on input and manages to burn it correctly to the CD (preserving the Unicode characters in the filename), so it can be done.

[Edit 3]
StarBurn_ISO9660JolietFileTree_ImportTrack falls over (with an exception somewhere inside starburn.dll) if you try to import a session containing a filename with unicode characters in it (as burned by IMAPI). It's not looking good for Unicode filenames
[/Edit 3]

Regards,

This one is REMOVED from StarBurn SDK. Please don't use it. It will return with error code starting from version 11 and up.

That's OK, I don't. I'd remove it from the header files and DLL if I were you.

So how do we write Unicode filenames to Joliet CDs? I'd very much like to be able to do this.

Many thanks,

Regards,

Please use UDF with full Unicode support for now. We'll represent back new ISO9660/Jolient Unicode engine after V11 release.

I'm not sure if UDF CDs will play on all players (our app creates MP3 music CDs and DVDs). I'll wait for version 12! I can live with the problem for now.

Many thanks,

Stand-alone DVD players - YES (they all support UDF for DVD-Video), stand-alone MP3 CD players - probably not. So please stick with single-byte characters for now for the file names. Thanks!

OK, thanks for the tip.

Sorry in any case

hello,

still it is not possible to use Unicode in a Joliet disc ?
I have an error on adding to the disc image tree some files with unicode characters in their names.

So I tried to change the function StarBurn_ISO9660JolietFileTree_Add to the correspondent wide function StarBurn_ISO9660JolietFileTree_AddW. The function was not present in Starburn.pas, but is is still present in the help, so I added it.

Still doesn't work (EN_SYSTEM_CALL_FAILED).

Exception text: CStarBurn_FileTree::CreateFromRoot(): FindFirstFile( 'C:\Users\MyUser\Desktop\UnicodeTestFolders\?? ?????? ????? ??????? ???? ???\myfile.txt\*.*' ) failed, status 123!!!)

I'm using the latest StarBurn SDK release, provided by you for Delphi 2009 compatibility.

Please use UDF with complete Unicode support. We'll release re-worked ISO9660/Joliet/xxx engine after V12 release.

But I just finished to implement StarBun in my application ....
You sent to me a DataBurner sample application. Now I must change everithing ?
Is it difficult to change a Joliet data burner to UDF data burner ?
In any case, I haven't a Delphi 2009 sample application for UDF ...

When do you think will be released the support for Joliet unicode ? weeks ? months ?
I'm sorry for my impatience, but we need to have a precise timeline, because we are going to release a major upgrade of our backup software and we need to know when we can purchase the licensed version of StarBurn...

Not weeks definitely.

And what about my other questions ?

Is it difficult to change a Joliet data burner to UDF data burner ?
What are the main differences ?

I don't know the answers to these questions so it will be Andrew or Vitaly or Dima who'll answer them ))

Hello,

For building Joliet and UDF image used different API and some other call order .
We try to add UDF support in DataBurner Delphi 2009 sample on the next week.
