Github repository is here.

For all requests for bug fixes and enhancements made in this thread, it would also be helpful if you can also post them to the issue tracker as well.

When reporting a crash or a bug, please provide a sample file and steps that can consistently reproduce the issue.

Hi,

Thanks for your work...I really appreciate.

I'm wondering if is there a way to change colors from BD sup files using this tool ? My input are sup from BD and my target are also sup files dedicated to BD but most of the time resized...

If not possible yet, may I ask this as a feature request ?

[mini-moose]

great to see you are carrying dev paradoxical!

I'm really no expert, in fact I know abosoutely nada.
I tried a sup file I had the sassbot versions crash on. Yours doesn't and it converts it to 1280x720 a lot faster than the old java versions did, but something is odd.
The vobsubs created by java 400 is 6.2mb while with new ++, only 1mb. I can't really see a difference in the result but it still seems weird running them on cmd also seems odd:

java ends with:
Decoding frame 1268/1269 at offset 0x01db9cb5
WARNING: fade out detected -> patched palette
Decoding frame 1269/1269 at offset 0x01dc060a
WARNING: fade out detected -> patched palette
There were 1048 warnings

++ new ends with:
Decoding frame 71/223 at offset 00c5820d
WARNING: fade out detected -> patched palette
Decoding frame 72/223 at offset 00c9e945
WARNING: fade out detected -> patched palette
There were 144 warnings
There were 157 warnings

you should upload your file somewhere...it might help to debug or fix the crash.

Probably due to a couple of bugs I fixed. Also, I did pretty extensive memory and performance profiling and fixes. So performance has dramatically improved. There's one more memory leak I still need to fix though, which I'll get in 1.0.2.

Okay, I'll check to see what the difference might be. It shouldn't be that dramatically different.

Okay. Without the file I can't really do much.

Yeah it doesn't do BD sup color editing currently. But it can go on the list.

Edited to add:

OS X binary is now up. I finally fixed all the issues with my statically linked Qt.

the processing time on standard sups is still a little slower than the java one. I ran the same sup with 720p resizing on both and timed it. about 5-6secs faster on the old java but I think that's still better than it was. 6 seconds are not gonna kill me
On this non-standard sup java takes around 3mins vs less than a minute on your latest version and as I said the end vobsub size is about 1/6.

Also from a non-expert view the cmd info seemed odd. java got to 1269/1269 and ++ 72/223. They might just use a different routine. Just pointing it out.
I'm sure you'll be able to tell more trying out the sup file provided.

thanks!

Yeah, there is definitely something amiss there.

Edit to add:

Checking the 1.0.0 version and it spews a ton of errors, too. So, I'll track it down here in a bit.

Edited to add again:

So more interestingly is that 4.0.1 Java version processes that sup with no "missing end time of frame" warnings. The 1.0.0 of ++ spews a bunch of those warnings which also matches what 5.1.1 Java does as well. 1.0.1 only has those warnings for far less frames. But the 1.0.0 and 5.1.1 still get the same timings as the 4.0.x Java versions, while 1.0.1 has something broken for sure. Interesting for sure.

This is actually an extract (a few minutes). SupRip does not have problem with it.

So I loaded it with 1.0.1 and saved it out as every format with no crashes. Any other info you can provide? What exactly did you do to get it to crash?

[Music Fan]

I tested it again and actually it works with a shorter name in a root folder instead of a subfolder , the path was maybe too long. But it's not very long ; around 20 characters for the name of the sup and also 20 for the name of the folder (no subfolder), it looks like :
K:\folder containing HD sup subtitles\my cool sup blu-ray extract.sup
It works with ;
E:\my extract.sup
The crash happened just after loading the sup. Now I know that I have to use short paths but if you can allow longer names (and/or paths), it would be nice

I think that's a red herring. The path I loaded the subtitle file was way longer than 20 characters. The path was "C:\temp\BDSup2SubPlusPlus\bdsup2sub++-build-desktop-Qt_4_8_4__qt4_8_4__Debug\release\extract french (Blu-ray sup).sup"

[Music Fan]

Now it works with the long file name while I didn't change anything.

I don't know what to tell you. The application itself does allow or disallow the length of path and/or file names.

mini-moose I fixed your issue. 1.0.1 version has been refreshed with the fix. Windows binary link has been updated. OS X binary will have to wait about 5 hours until I get back to my Mac.

thanks! I'm running it now. doing resize to 1280x720 with Mitchel.
It seems to be taking a very long time..I'm at 10mins now and it's only at 330/1269. Are you getting similar processing times?

It's not super fast, but I finished in about 2 mins. This was on my Quad core i7 Mini. I'll do some more performance analysis and see if there isn't any more low-hanging fruit especially with some of the more slow filters. Just as a benchmark, Bilinear was about 30 seconds.

Edit to add:

I did notice when profiling before that 720p was slower than going to either NTSC or PAL resolutions which seemed a bit weird so I'll see what I can find out with more profiling.

Just to add as well, the 5.1.1 Java version is also quite a bit slower doing the 720p with Mitchel too. Nearly 20-30% slower on the same system with a couple of test runs.

hmm it just finished here. took 29mins and I'm not sure it reached the end (if cmd output is an indication) :
WARNING: fade out detected -> patched palette
Decoding frame 1145/1269 at offset 01ad769b
There were 144 warnings
There were 1048 warnings

my pc is a sandy bridge i7 so not a very slow one.

Yeah it didn't take anywhere near that long and that's with quite a few things running at the same time.
