The net5 directory is there, lots of files are there, but PgsToSrt.exe and .dll are missing.

when executing
dotnet D:\pgstosrt\PgsToSrt.dll --input "D:\23.sup" --output "D:\23.srt" --tesseractlanguage tha
on a specific sup file I got

yes I have the tha tesseractlanguage
you can find the sup file here

I am using:

• Ubuntu 20.04.2 LTS
• libtesseract4
• dotnet 5.0.102

$ ldconfig -p -v | grep libdl
libdl.so.2 (libc6,x86-64, OS ABI: Linux 3.2.0) => /lib/x86_64-linux-gnu/libdl.so.2
libdl.so.2 (libc6, OS ABI: Linux 3.2.0) => /lib/i386-linux-gnu/libdl.so.2
libdl.so (libc6,x86-64, OS ABI: Linux 3.2.0) => /lib/x86_64-linux-gnu/libdl.so

Simiar to issue #6, caused by the missing libtesseract3 package

Is it possible to tell PgsToSrt to convert all files in a directory? Does it depend on the container?

Bonjour,
J'ai bien utilisé votre création qui fonctionne très bien.
Je vous avoue l'avoir utilisé pour mon logiciel "TAO-MKV" mais je suis passé par un autre processus en tesseract 5.0.X LSTM.
Cependant même si votre programme ne soit pas rapide, il reste très efficace ET surtout léger (j'ai pu le réduire à 19Mo contre 250Mo pour l'officiel "sans les tessdata bien sur" ).
Je n'ai aucune idée de comment extraire les bmp sous-titres et les timestamps (sous forme texte) mais si vous souhaitez inclure votre savoir faire, rapidité et efficacité dans TAO-MKV, https://github.com/serpafi/TAO-MKV
on sera ravi de votre travail qui ne sera pas spoiler mais mis en avant (textes, liens ou autres seront publiés directement dans le logiciel).
Cordialement

I see the examples for MKV and sup files, but I used MKVToolNix GUI to extract my subtitles, which gave me MKS files. Also, how can I have PgsToSrt convert all tracks in the MKS file?

I wanted to use PgsToSrt under Ubuntu 23.04 but it comes with libtesseract5 and I did not find what to install libtesseract4. Is it possible to make PgsToSrt use libtesseract5 instead of libtesseract4?

You changed the code-style of the original code which makes merging upstream changes a lot harder on yourself.
In one case, IMO get => TimeSpan.Milliseconds; is more readable than what you changed it to:

get
{
    return TimeSpan.Milliseconds;
}

You can refactor your modifications so you override functionality and thus you can use the upstream nuget package and make updates a lot easier for those dependencies. Git submodules can be utilized if you must have a clone of the code in your project.

Do you plan on adding "Fix OCR errors" like subtitle edit option to resolve badly OCRd text ?

Hi!

I am seeking your help today as I see the following error when executing :

dotnet PgsToSrt.dll --input /video/input/Sieben.mkv --track 3 --output /video/input/test.srt

Do you have any idea about the root cause?
Am I missing something?

It doesn't seem like the Tesseract trained data set is optional (i.e. 'fast' vs 'best') and as far as I can tell, you are using 'fast'. Is that the case?

There may also be corruption somewhere in the trained data you have (at least, for eng) as I just noticed totally nonsensical series of characters in the conversion of a single basic word when it is multi-line. Something like...

The brown fox jumps over the lazy
qj2]a%sLo1

It will be easier to install like dotnet tool install -g PgsToSrt.

Thanks a lot!

Hi - Trying to use your script and got the following error:

Not sure how to generate more debug info. Any assistance is appreciated .. Thanks.

The Dockerfile in the current master branch uses a .NET SDK 5.0 base image which can't target .NET 6 targets.

Relevant output for docker build -t pgstosrt .

Step 4/9 : RUN cd /src &&     dotnet restore  &&     dotnet publish -c Release -o /src/PgsToSrt/out &&     mv /src/entrypoint.sh /entrypoint.sh && chmod +x /entrypoint.sh &&     mv /src/PgsToSrt/out /app

Steps to reproduce:

git clone https://github.com/Tentacule/PgsToSrt.git
cd PgsToSrt

# checkout the latest release v1.4.2 or master at 38fd03e57f
git checkout v1.4.2

docker build -t pgstosrt .

Quick fix:

Change the .NET SDK base image to 6.0
Specify the framework to target net6.0 (because the project specifies both 5.0 or 6.0 as potential targets, one must be explicitly chosen)

Alternatively, leave the .NET SDK base image to 5.0.101
Specify the framework to target net5.0

fixed by #12

Build failed on Linux without specifying the framework, please consider update README.md

dotnet publish -c Release -o out --framework net6.0

Hi,

I want to convert .sup (PGS) to .srt with your libs using docker :

docker run -it -v /share/CACHEDEV1_DATA/Multimedia/Movies/Test:/data -e INPUT=/data/Mission.Impossible.Fallout.2018.MULTi.TRUEFRENCH.2160p.UHD.BluRay.REMUX.DV.HEVC-BEO.6.en.sup -e LANGUAGE=eng tentacule/pgstosrt

But I have this error :

I have a QNAP NAS.

Thanks in advance for your help.

On ArchLinux the required library liblept.so is actually called libleptonica.so. I had to make the following symlink in order to make PgsToSrt to read it: ln -s /usr/lib/libleptonica.so.6 /usr/lib/liblept.so.5. Would be good if the program could read the name libleptonica.so by itself.
