Converts VobSub subtitles (.idx/.srt format) into .srt subtitles.

VobSub2SRT is a simple command line program to convert .idx / .sub subtitles into .srt text subtitles by using OCR. It is based on code from the MPlayer project - a really really great movie player. Some minor parts are copied from ffmpeg/avutil headers. Tesseract is used as OCR software.

vobsub2srt is released under the GPL3+ license. The MPlayer code included is GPL2+ licensed.

The quality of the OCR depends on the text in the subtitles. Currently the code does not use any preprocessing. But I’m currently looking into adding filters and scaling options to improve the OCR. You can correct mistakes in the .srt files with a text editor or a special subtitle editor.

Building

You need tesseract. You also need cmake and a gcc to build it. With Ubuntu 12.10 you can install the dependencies with

sudo apt-get install libtiff5-dev libtesseract-dev tesseract-ocr-eng build-essential cmake pkg-config

You should also install the tesseract data for the languages you want to use! Note that the support for tesseract 2 is deprecated and will be removed in the future!

./configure
make
sudo make install

This should install the program vobsub2srt to /usr/local/bin. You can uninstall vobsub2srt with sudo make uninstall.

Static binary

I recommend using the dynamic binary! However if you really need a static binary you can add the flag -DBUILD_STATIC=ON to the ./configure call. But be aware that building static binaries can be quite troublesome. You need the static library files for tesseract, libtill, libavutils, and for their dependencies as well. On Ubuntu 12.04 the static libraries are only included in the dev packages! You probably also need the Gold linker.

For Ubuntu 12.04 you need the following extra packages:

sudo apt-get install libleptonica-dev libpng12-dev libwebp-dev libgif-dev zlib1g-dev libjpeg-dev binutils-gold

If linking fails with undefined references then checking what other dependencies your version of leptonica has is a good starting point. You can do this by running ldd /usr/lib/liblept.so (or whatever the path to leptonica is on your system). Add those dependencies to CMakeModules/FindTesseract.cmake.

Ubuntu PPA and .deb packages

I have created a PPA (Personal Package Archive) to make installation on Ubuntu easy. Simply add the PPA to your apt-get sources and run an update and you can install the vobsub2srt package:

sudo add-apt-repository ppa:ruediger-c-plusplus/vobsub2srt
sudo apt-get update
sudo apt-get install vobsub2srt

.deb (Debian/Ubuntu)

You can build a *.deb package (Debian/Ubuntu) with make package. The package is created in the build directory.

You can also create a source package and upload it to your own PPA by using the UploadPPA.cmake. But this is only recommended for people experienced with cmake and creating Debian packages.

Homebrew

Vobsub2srt contains a formula for Homebrew (a package manager for OS X). It can be installed by using the following commands:

brew install --with-all-languages tesseract
brew install --HEAD https://github.com/ruediger/VobSub2SRT/raw/master/packaging/vobsub2srt.rb

Gentoo ebuild

An ebuild for Gentoo Linux is also available. You can make it available to emerge with the following steps

sudo mkdir -p /usr/local/portage/media-video/vobsub2srt/
wget https://github.com/ruediger/VobSub2SRT/raw/master/packaging/vobsub2srt-9999.ebuild
sudo mv vobsub2srt-9999.ebuild /usr/local/portage/media-video/vobsub2srt/
cd /usr/local/portage/media-video/vobsub2srt/
sudo ebuild vobsub2srt-999.ebuild digest

You should be able to install vobsub2srt with emerge vobsub2srt now. If you want to use a newer version (3+) of tesseract you have to use layman. See #13 for details.

Arch AUR

There also exist a PKGBUILD file for Arch Linux in AUR: https://aur.archlinux.org/packages/vobsub2srt-git

Usage

vobsub2srt converts subtitles in VobSub (.idx / .sub) format into subtitles in .srt format. VobSub subtitles consist of two or three files called Filename.idx, Filename.sub and optional Filename.ifo. To convert subtitles simply call

vobsub2srt Filename

with Filename being the file name of the subtitle files WITHOUT the extension (.idx / .sub). vobsub2srt writes the subtitles to a file called Filename.srt.

If a subtitle file contains more than one language you can use the --lang parameter to set the correct language (Use --langlist to find out about the languages in the file). For some languages you might need to set the tesseract language yourself (e.g., chi_tra/chi_sim for traditional or simplified chinese characters). You can use --tesseract-lang to do this. In most cases this should however be autodetected.

If you want to dump the subtitles as images (e.g. to check for correct ocr) you can use the --dump-images flag.

Use --help or read the manpage to get more information about the options of vobsub2srt.

Bug reports

Please submit bug reports or feature requests to the issue tracker on GitHub. If you do not have a GitHub account and feel uncomfortable creating one then feel free to send an e-mail to <[email protected]> instead.

If you have problems with a specific subtitle file then please check if it works in mplayer first. If it does not then please report the bug to mplayer as well and link to the mplayer bug report.

For bug reports please run vobsub2srt with the --verbose option and copy and paste the full output to the bug report.

vobsub2srt's Issues

TESSERACT_DATA_PATH and tesseract 3.03_rc1

Hi,

My system is gentoo.
If I use the ebuild from packaging/, vobsub2srt is working fine with tesseract-3.02.
But, if I upgrade tesseract to 3.03_rc1, vobsub2srt fails like this :

$ vobsub2srt 01
Error opening data file /usr/share/tesseract-ocr/tessdata/fra.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'fra'
Tesseract couldn't load any languages!
Failed to initialize tesseract (OCR).

The only way I found to make it work with tesseract 3.03_rc1 is to rebuild vobsub2srt to force TESSERACT_DATA_PATH at configure phase, like following in the ebuild :

src_configure() {
      local mycmakeargs=(
              -DTESSERACT_DATA_PATH="/usr/share"
      )
      cmake-utils_src_configure
}

So my question is : why do I need to force the TESSERACT_DATA_PATH value with tesseract 3.03_rc1 but not with 3.02 ? Is this normal ?

Thanks.

Blank pgm images and no text data

I'm having trouble getting VobSub2SRT to work.

On my files test.idx/test.sub, running the command:

vobsub2srt --langlist test

Produces output:

Languages:
0: en

Using the command:

vobsub2srt --lang en --tesseract-lang eng --dump-images test

Appears to work, with output:

Selected VOBSUB language: 0 language: en
Wrote Subtitles to 'test.srt

However test.srt contains the timing data but no actual text.
~500 .pgm files are output but they are all blank.

Loading the same idx file with avidemux OCR Vobsub->SRT tool shows all the correct subtitles are in the file.

Any way I can get some more debug output?
Running latest git master on Ubuntu 14.04 64-bit.

Thanks.

Short options not recognized

vobsub2srt -l foo bar yields: ERROR: unknown option '-l'.

Make default tesseract data path configurable during build

The default tesseract data path is currently hard coded in vobsub2srt.c++. This should be configurable during configuration.

Thanks to Kevin Krouse for pointing that out.

Creating a threshold option to convert all colours to either full-black or full-white?

I've found VobSub2SRT to be a great tool, thank you.

However with the subtitle streams I'm using there are a lot of repetitive OCR mistakes that seem to be caused by the grey pixels outlining each of the (off-white) characters.

You can see an example image here:
https://www.dropbox.com/s/dkbd9fh6hfr26fa/stvoy2x23-en-513-orig.png?dl=0

I've found that if I modify the palette line in the idx file to change the grey colours to black, leaving only one lighter colour, I get fantastically better results.

The images from the modified idx look like this:
https://www.dropbox.com/s/p08mk4204717dnx/stvoy2x23-en-513-bw.png?dl=0

I think that in the modified version it is easier to distinguish individual characters.

I'm guessing that this could be a common problem, so I was thinking of a really simple option to add to VobSubSRT that would perform the step automatically.

The simplest way I can think of would be to specify a threshold value as a parameter, and to convert every colour in the palette above the value to white and below it to black, ie --bw-threshold 200.

1. Does this sound sensible to you?
2. At what point in the code would this make the most sense?

Dedicated --langlist option

For files with multiple languages --verbose can be used to get a list of languages. But the behaviour of --verbose is not very predictable and the list of languages is not printed if there is only one language in the sub file. Adding a --langlist option could make it easier to write scripts.

This issue was reported to me by email from Enrico Gherardo.

output subtitled with overlapping errors

If you don't mind I'd put 2 more bugs that happened to me after the .srt was generated.

When i played it with VLC I realized the subs where getting overlapped, so I CHECKED ERRORS with the subtitleeditor software(great one too btw).

here is the output of the check errors.

Even if subtitleeditor has a menu option for TRY TO FIX ALL, apparently it can't manage to do so.

Thanks again.

Blacklist doesn't seem to work

Hi Guys

I'm not 100% sure if I'm passing the paramater in the right format, but it would seem that the blacklist doesn't work quite right.

I tried

vobsub2srt --blacklist \| filename

and

vobsub2srt --blacklist "|" filename

With both options words like |'|| or wou|d still shows in the SRT file

As a quick fix, can I change line 137 of vobsub2srt.c++ from

  tess_base_api.SetVariable("tessedit_char_blacklist", blacklist.c_str());

to

  tess_base_api.SetVariable("tessedit_char_blacklist", "|");

and remove the if statement around it? (Sorry, I have zero C++ experience).

Thank you

Werner

error during configure with tesseract 3.01

-- Configuring incomplete, errors occurred!

I am on a gentoo system and using tesseract 3.01 and libavutil version 50.43.0
with tesseract 2.04 the compile works fine, but I ran into the same problem reported here:
#4
after upgrading to tesseract 3.01 without recompiling vobsub2srt, I get the unicharset file not found error. therefore I tried to recompile.

I figure this has something to do with tesseract 2.04 and tesseract 3.01 not being compatible (from the tesseract ReadMe wiki http://code.google.com/p/tesseract-ocr/wiki/ReadMe ):
"Another important change is that you should really be using TessBaseAPI if you are linking with another program. In Linux (non-Windows) the main library is now libtesseract_api.a instead of the old libtesseract_full.a. "

Make statically linking less painfull

Currently statically linking is a bit of a hack. This is mainly due to the lack of pkg-config support in leptonica and thus it requires manually tracking all the library dependencies of it (which is quite a lot). Tesseract finally has pkg-config support in 3.02.02 (not in Ubuntu 12.10 though).

• pkg-config issue for leptonica: https://code.google.com/p/leptonica/issues/detail?id=72 (Update: Just as I wrote this issue the pkg-config patch in leptonica was accepted for 1.70)

Statically linking on Ubuntu 12.10 (and Debian) is currently not working because no static version of libjbig is provided. See https://bugs.launchpad.net/ubuntu/+source/jbigkit/+bug/1098361 Which is a dependency of their leptonica package.

This issue was also reported by e-mail

Use Tesseract 4 installed without root

Hello,

I'm wondering if it's possible to install VobSub2SRT and to specify the path of the Tesseract 4 installation (in my home), because I want to use the last version and I install it by myself.
I already have VobSub2SRT working but with Tesseract 3.

Thank you very much.

windows?

can I build this on windows?

vobsub2srt doesn't detect subtitles in this file.

I am trying to use this program on vobsubs extracted from an mkv track. I don't have an IFO file. The subtitles were extracted using mkvextract. The program appearsYou can download the offending .sub/.idx files from my dropbox.

Here is the file: http://dl.dropbox.com/u/4660781/problem_vobsub.zip

I believe that at https://github.com/ruediger/VobSub2SRT/blob/master/src/vobsub2srt.c++#L177 vobsub_get_next_packet returns -1 causing the program to skip the main loop entirely. If you could shed any light on the situation that would be incredibly helpful.

Thanks in advance.

--dump-images outputing some fuzzy .pgm

So sorry for reporting bugs again, if I'd know C/C++ I'd fork it myself and send u patches instead though, anyway I'd create the bug first so I could assign it to me, so please don't bother if I create too many issues.

I built the latest code, and used the --dump-images

I realized that the OCR was still running(could it be possible that this option would make the program not to run the OCR) , or adding some --no-ocr option? That could be useful for the GUI project.

Nevertheless, while the OCR is correctly done, many of the .pgm generated appear like this:

https://dl.dropboxusercontent.com/u/1599184/others/gxp-spirit.45.xvid-002.pgm

it is quite odd, because the OCR for that line is well generated.
Thanks.

vobsub2srt ebuild for gentoo

Hi,

I was not sure, where to put this, so I am putting it here.
I have created an ebuild that allows installing vobsub2srt and its dependencies on a gentoo machine. I put the ebuild code below. just copy and paste it into a file called vobsub2srt-9999.ebuild in the directory /usr/local/portage/media/video/vobsub2srt/. Then, you need to open a terminal, cd to that directory and run ebuild vobsub2srt-999.ebuild digest. Afterwards you can compile and install the latest git version of vobsub2srt by running emerge vobsub2srt
It works with a stable release of gentoo where it will use tesseract 2.04-r1. However that tesseract version is quite old. in order to get tesseract 3.x to run, you need to enable the 'stuff' portage overlay as follows. run emerge layman then run layman -a stuff which will enable a small gentoo overlay that contains tesseract 3.01 and its dependencies that are not in the standard portage tree. Afterwards, you can again just emerge vobsub2srt which will then use tesseract 3.01.
Here is the ebuild:

make uninstall does not remove $prefix/share/doc/vobsub2srt/ directory

Calling make uninstall does not remove $prefix/share/doc/vobsub2srt/ directory. CMake does not keep track of created directories in install_manifest.txt. Adding a manual rm -rf command could work but would require knowing the prefix in the Makefile.

multiple subtitles of same language

Hi,
I have a file with two english subtitles:
--langlist:
Languages:
0: en
1: en

Using the --lang en option, stream 0 is selected, at least according to help and manpage there is no option to choose stream 1.
In this case stream 0 is the HOH-subtitle, while stream 1 containes the subtiltes for the non-english part only.

 VobSub2SRT is a simple command line program to convert .idx / .sub subtitles into .srt text subtitles by using OCR. It is based on code from the MPlayer project - a really really great movie player. Tesseract is used as OCR software.

wrong lang prefix makes the operation fail

Trying to extract french subtitles to srt from idx/sub than contains english, spanish and french, I installed the french localization for tesseract but vobsub2srt conversion still fails because it's looking for files prefixed fre. when the installed files are prefixed with fra.

for example vobsub2srt requires fre.unicharset when the french tesseract package installed fra.unicharset

VobSub2SRT fails to build with tesseract 3.02

Changing CXXFLAGS from -pedantic-errors to -pedantic (and adding -Wno-long-long) should fix this.

This seems to actually be a bug in tesseract if they want C++98 compliance. C++11 allows comma at end of enumerator list. TODO: Report upstream?

Not working in every way

I dumped my vobsubs using
mencoder -o /dev/null VTS_07_1.VOB VTS_07_2.VOB -oac copy -ovc copy -vobsubout subtitle
Subtitledit can open it fine so I think files fine.
However when using vobsub2srt I get an srt with only time codes.

I executed 'vobsub2srt --dumpimages --tesseract-lang eng subtitle'

and all images appear to be blank like so
https://dl.dropboxusercontent.com/u/26289275/sub/sub.pmg

Here is the sub and idx files
https://dl.dropboxusercontent.com/u/26289275/sub/subtitle.sub
https://dl.dropboxusercontent.com/u/26289275/sub/subtitle.idx

No PPA for 16.04

... But the build works!

Can't find file?

I'm sorry if this is the wrong place to put this but I'm having a very strange issue. I compiled and built from the latest version.

VobSub2Srt fails silently

Please see the linked .sub file: http://dl.dropbox.com/u/442163/vobtest.zip

--dump-images doesn't do anything either, but the file works in standalone mplayer.

vobsub_get_next_packet(vob, &packet, &timestamp) returns -1, so the loop is never entered.

feature request: dump only failed images.

ERROR: OCR failed for 1
ERROR: OCR failed for 23
ERROR: OCR failed for 133
ERROR: OCR failed for 367
ERROR: OCR failed for 367
ERROR: OCR failed for 386

Can you make an argumen to dump only the images that failed to ocr? And if possible allow them to be opened in external image editor so I can be prompted on the cli for a fix?

deb package script man directory incorrect

hi - first of all thank you for your great application - make package results in vobsub2srt.1.gz being placed in incorrect directory path

language support weird

in my subtitles file, when i listlangs, i get "zh", so when i select "zh" with --lang, vobsub2srt looks for zho.traineddata in tesseract. it should be looking for chi_* or perhaps i should be able to specify this thing directly.

linking against libavutil no longer needed?

make package (deb) broken - error in 'Version' field string 'unknown-dirty'

Hi ruediger

Already using couple of years your amazing OCR tool. I am setting up my new laptop right now and noticed that the compiled deb package is broken and refuses to be installed via dpkg. Info to reproduce:

OS: debian jessie/stable

configure: ok, no issues
make: ok, no issues
make package: built package 'vobsub2srt-unknown-dirty-Linux.deb' refuses to be installed via dpkg with following output:

dpkg -i vobsub2srt-unknown-dirty-Linux.deb

dpkg: error processing archive vobsub2srt-unknown-dirty-Linux.deb (--install): parsing file '/var/lib/dpkg/tmp.ci/control' near line 2 package 'vobsub2srt': error in 'Version' field string 'unknown-dirty': version number does not start with digit

Could you please fix this and if possible upload a new release source code? It fails with release source code VobSub2SRT-1.0pre7 and it also fails with todays source code.

Thanks in advance, and your work is highly appreciated!

I got an "Aborted" error

Whilst running the program I got:

vobsub2srt: unicharset.cpp:76: const UNICHAR_ID UNICHARSET::unichar_to_id(const char*, int) const: Assertion `ids.contains(unichar_repr, length)' failed.
Aborted

This was on line 1,313 of a 1,620 line .srt file. There didn't appear to be anything different about the next image to be ocr'ed?

error : not support my lang?

Hi
When i use vobsub2srt in my debian(amd64) this error occured :

alireza@debian-lap:/media/1E2AB0A8/Sec I/02$ vobsub2srt Rome-S01E02

Cya.

Will this work on bluray sup files?

Since they are pretty much the same thing than idx/sub files...

Subtitle text slanted in PGM export

Reported by e-mail.

http://dyn.fergaldaly.com/~fergal/vobsub/ is exported slanted. This does not seem to happen when displayed with mplayer or other tools.

Check if this issue happens in current mplayer and update the subtitle code.

Text export does not seem to be affected. Therefore smaller priority.

VobSub2SRT output 0KB probably problem finding out languages id?

I'm using the PPA latest .deb packages,

when I run
vobsub2srt gxp-spirit.45.xvid --dump-images
it returns
Wrote Subtitles to 'gxp-spirit.45.xvid.srt'

with a 0KB gxp-spirit.45.xvid.srt file.

I realized it may have to do with vobsub2srt not being able to decode the list of languages, it also shows "0:\n" when I use --langlist parameter.

here are the VobSub subtitle for you to try if you want, with smplayer, the subtitles are correctly displayed and the language EN shows up.

https://dl.dropboxusercontent.com/u/1599184/others/gxp-spirit.45.xvid.idx

Thanks a lot to take a look.

Chinese character error

Hello
i've been trying to use vobsub2srt to convert chinese sb to srt.
Using the following command :
vobsub2srt --lang zh --tesseract-lang chi_sim subtitles

however the conversion is not working well, a lot of character are not recognized correctly, even so the font used in vobsub is perfectly readable.

Here the vobsub screenshot :
http://img546.imageshack.us/img546/4601/u1xu.jpg

Here the converted sub :
http://img571.imageshack.us/img571/5273/iyx2.jpg

We can easily see that some characted have been simplfied.
Here are the sub/idx files.
http://www.2shared.com/file/ZvL3xukf/subtitles.html
http://www.2shared.com/file/1u7L35fD/subtitles.html

Is this normal? is there a work around ?
