bdsup2sub++ - convert and tweak bitmap subtitles.

[Selur]

there hasn't been an update for 7 month, see: https://github.com/amichaelt/BDSup2SubPlusPlus .
So yes, at least for the moment the project seems to have stopped. (latest version is still a lot newer than BDSup2Sub)
Sorry, never tried DVB-Sub subtitle which BDSub2Sup++.

[Music Fan]

Ok, so I guess he still hadn't added DVB-Sub support because he hadn't last time he answered me (on previous page).

[Selur]

yup, his replay was from may and since the last update was from "Apr 17, 2013" (see: https://github.com/amichaelt/BDSup2SubPlusPlus/commits/master) I think you are right.

[Music Fan]

Actually ProjectX can demux DVB subtitles ;

http://www.videohelp.com/tools/ProjectX

It seems to work but I get very special colors when I open the sup in SubtitleCreator, I still have to understand how to correct these subtitles.
ProjectX creates sup, sub, idx, ifo and txt.
SubtitleCreator can open sup, sub, idx and ifo, I don't know what is better.
And it seems to be converted in 720.576 while my TS is in 1920.1080.

[Selur]

ffmpeg might also able to extract them. I thought the main goal was to convert them,...

[Music Fan]

Yes, I wanna convert them to make an AVCHD with multiAVCHD (so actually not really an AVCHD but a bastard format between AVCHD and Blu-ray), and I need a sup file compatible with multiAVCHD (blu-ray type sup). I'd like also to change colors and position and I believe it can be done without OCR.
How does it work with ffmpeg ?

I'm talking about bit-map subtitles, not teletext sub.
I believe it's the norm ETSI EN 300 743.

[Selur]

probably something like:

ffmpeg  -i 00038.m2ts -c:s copy "track_05 - Subtitles.sub"

could be used, never really played with DVB subtitles, so can't say for sure.

[Music Fan]

I tried but it didn't work, I got several error messages and a 0 KB file was created.
I also tried sup extension instead of sub, no file was created.

[Selur]

-> google a bit and maybe you can find a solution

[Music Fan]

I found several topics about DVB-sub muxing and de-muxing with ffmpeg but no one is clear, I still didn't find any command I could use.
I don't know ffmpeg, it doesn't look easy to use.

[Selur]

then you are lost -> best ask inside another thread and may be someone with ffmpeg and dvb-sub experience can help you further good luck!

[Music Fan]

Ok, I created a topic in the subtitle part of the forum ;

Looking at his GitHub profile, I can see a couple new forks he created but very little contribution for this year.

[Chetwood]

I'd also like to know that. I was wondering if he could shed some light on how to identify forced subs on BDs.

[stax76]

Does anybody know how to contact the author? I have a sample clip where sup to sub conversion fails.

[cdlvcdlv]

Does anyone how to compile the source code in Windows?
I have tried with qt-opensource-windows-x86-mingw492-5.5.0.exe (958 MB) and qt-opensource-windows-x86-mingw482-4.8.6-1.exe (328 MB) + i686-4.8.2-release-posix-dwarf-rt_v3-rev3.7z (44 MB) but I get the same error. (I would prefer not to download/install such huge compiler.)

This creates Makefile and another files. No errors.

If this is not the place to ask this question, maybe someone might tell me where it would be.

is a Qt4 program. make sure you use qmake from qt4 instead of qt5

If I understand the version numbers then the first attempt was doomed to failure. But maybe I had a chance in second one.

The numbers in bold are the relevant ones, aren't they? Strangely enough, the two attempts stopped with the same error message:

#include <QxtCore/QxtCommandOptions>
                                   ^
compilation terminated.

So I think there is something more I'm missing.

By the way. What would be the minimal environment needed to compile bdsup2sub++? This is around half a GiB to generate a 4 MB exe... And even so without success.

Is relevant the compiler? In qt4, three choices exist. Namely - qt-opensource-windows-x86-mingw482-4.8.6-1.exe, qt-opensource-windows-x86-vs2008-4.8.6.exe and qt-opensource-windows-x86-vs2010-4.8.6.exe.

Saludos, compañero espanishtaní.

[sl1pkn07]

yes, Qt4 is a 4.8.X series, Qt5 is a 5.x.x series

ok, i see, you need install qxt https://bitbucket.org/libqxt/libqxt/wiki/Home

[cdlvcdlv]

Dl and installed libqxt-0.6.2.zip from the link you posted, unzipped, run configure.bat, make and make install. Lots of warnings about vars declared but not used, but it generated the files and copied them to their folders.

Then go to bdsup2sub++ source folder, run qmake && make... lots of warnings again and in the end...

After some searching, I found out that I should have configured libqxt with -debug (configure -debug), what I did. Then, the "qmake && make" runs OK. It's a 14 MB debug exe, with dynamic linking, so it needs 231 additional MB to run (libgcc_s_dw2-1.dll, libstdc++-6.dll, libwinpthread-1.dll, QtCored4.dll, QtGuid4.dll, QtXmld4.dll, QxtCored.dll). But placing the dlls in the .exe folder it works. If I manage to do something useful, I would find out how to make static linking to create the neat 4 MB of the usual bdsup2sub++ releases. It would be useful to know what compiler was used (mingw, VS2008 or VS2010). There may be differences regarding to final size and performance.

The code is well-structured, but not much documented about how the conversions are done so that you can understand clearly why it does what it does.

@Chetwood: Some warnings in the code are related to forced subtitles. I hope they shed some light on the question.
