bdsup2sub++ - convert and tweak bitmap subtitles.

It shouldn't have any effect on any other valid SUP files because it only checks for the specific case of the "imageobject" for the subpicture having a width and height of 1920x1080. Anything that does have that would be another pathological file.

Yeah. No guarantees on when, though. Trying to fix some of the remaining bugs that Sassbot didn't get to and crashes like this that effects both version before more enhancements. DVB Sub will probably come first as well since it's simpler to implement.

So as a little update, I've fixed BDSUP parsing code to finally handle subpictures with multiple image objects correctly which means that it no longer crashes in files such as this. It is now hugely simplified and easier to follow.

BTW can anyone post any examples of BD SUPs that use multiple regions in a subpicture so I can use them to run through the code just to double check everything?

And the update version is 1.0.1 or 1.0.2a??

where i can download it?

You can't. It's code I haven't pushed out yet. Just letting people know that I've fixed that. I'll make a git test build with the changes in a day or so once I thoroughly test it.

oki thanks.

Just as an additional heads up, until I post a build with the multiregion support I will be pushing lots of incremental changes to Git. If you are building from Git expect there to be breakages along the way until things stabilize again. While the parsing for SUP files works, decoding the separate regions and merging them into a single image is still wonky, proper BD SUP output maintaining the multiregions needs to be added. Also on the BDN+XML side, the input reading needs to be fixed so that any event with multiple graphics is supported correctly along with correctly outputting the multiple graphics when being generated from a BDSUP file with multiregion subpictures. All-in-all, it'll be big refactoring and change job so it might take most of the week to fix up, but in the end the tool will be much more useful in light of its current restrictions.

using 1.0.1 if I call 'bdsup2sub++.exe -h'
I just get a bunch of:

QTextStream: No device

outputs on the console and a Windows user just reported that bdsup2sub++.exe crashes when closed with:

not sure what's happening there, but it seems like there's a problem with some NVIDIA driver,... (can't reproduce his crash on my machine)
He's using Windows 7 64bit
primary graphic using Intel HD drivers v8.15.10.2827
secondary graphic: NVidia (GTX460) driver v306.97

Yeah, I don't get a crash but I see what the error is and I fixed it locally. It'll get rolled up into the 1.0.2 version.

You can also compile a fixed version of 1.0.1 using this patch file. Just pull down the 1.0.1 tagged version. Otherwise, I'll post a 1.0.2 at the end of the week with the fix.

[Selur]

Thanks! On the road atm. and no compiling enviroment at hand, so he will have to wait till the end of the week.

Unless something goes awry I should have it by Friday at the latest. I'm making good progress on multi-region stuff. Got SUP parsing, decoding and output down. Now just need to fix BDN+XML import and export.

[Selur]

"I should have it by Friday at the latest" ...

[Music Fan]

He didn't say which friday

As I said, "Unless something goes awry". A few things popped up that diverted my time from being able to finish things up when I wanted. Next week it should be finished.

[Selur]

I know, just wanted to check. Thanks for the info.

Hi, bdsup2sub is having dificulties dealing with this subtitle file: http://www.sendspace.com/file/igjzoy

It's from the star wars bluray which is using seamless branching. This sup file comes from a very short m2ts file (2min opening crawl) and contains no actual subtitles inside, which I guess is the cause of the problem.

Yeah, it is simply telling you that there are no subtitles. The only real issue is just making the error message more user friendly. There's not really much else can be done.

[nautilus7]

Yes, but i want to convert it to bdn xml and i can't.

You'll ask why i would like to do that? Because i want to re-author the bluray and it must contain these empty subs, because as i mention before it is seamless, so this part's subs are empty, but others aren't.

Then just create an empty BDN+XML with avs2bdnxml.
