I can't reproduce the issue on master and on 0.88.

jamoore5 · 2020-02-19T13:48:49Z

I am on a raspberry pi 4 if that helps troubleshoot why I am getting this error.

How did you install ccextractor?
Did you build it yourself or is it included in the repos (if yes please mention the distribution you're using) or something else?

jamoore5 · 2020-02-19T13:54:54Z

I followed this tutorial https://magpi.raspberrypi.org/articles/make-comics-from-tv-recordings

cd
git clone https://github.com/CCExtractor/ccextractor.git
sudo apt install -y libglfw3-dev cmake gcc libcurl4-gnutls-dev tesseract-ocr tesseract-ocr-dev libleptonica-dev
cd ccextractor/linux
./build
sudo mv ./ccextractor /usr/local/bin/

However, I had to remove tesseract-ocr-dev from the install

NilsIrl · 2020-02-19T13:56:51Z

However, I had to remove tesseract-ocr-dev from the install

Why? tesseract-ocr-dev (AFAIK) is required to have OCR support.

jamoore5 · 2020-02-19T13:58:49Z

sudo apt install -y tesseract-ocr-dev
Reading package lists... Done

Package tesseract-ocr-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libtesseract-dev

E: Package 'tesseract-ocr-dev' has no installation candidate

NilsIrl · 2020-02-19T14:00:08Z

Could you try with the libtesseract-dev package instead? (They changed the name of the package)

jamoore5 · 2020-02-19T14:00:54Z

installed it but still getting the same error

NilsIrl · 2020-02-19T14:01:57Z

installed it but still getting the same error

segfault? Also from what I can tell, the .ts file you're using doesn't have any subtitles.

Once you've installed libtesseract-dev, you need to rebuild ccextractor.

Both VLC and ffmpeg detect there is a subtitle stream but when playing through VLC no subtitles were shown.

jamoore5 · 2020-02-19T14:15:41Z

Also from what I can tell, the .ts file you're using doesn't have any subtitles.
Thanks, I will investigate what went wrong in the convert. But the last one I had with burned-in subtitles it did not error, just no output. In VLC, I see the subtitle file but it does not show up when played. I will investigate what went wrong with the convert.

just thought the error was strange, but my file is definitely bad.

NilsIrl · 2020-02-19T14:19:10Z

just thought the error was strange, but my file is definitely bad.

I don't have an error though. It shouldn't seg fault.

canihavesomecoffee · 2020-02-19T14:40:30Z

But why is that assert being triggered? I think that might be the cause of that segfault :)

I can't reproduce on a Raspberry either.

Also any tips on how to convert am mp4 with subtitles to a ts with subtitles?

NilsIrl · 2020-02-21T00:22:06Z

Seems to segfault inside of tesseract.

cfsmp3 · 2020-02-21T01:34:01Z

@jamoore5 Run it with valgrind, maybe it will give info some clue. Also note that you are using tesseract 4, not tesseract 3 which is really like to be the reason we're seeing different things.

valgrind ccextractor -out=spupng  S3E01.ts

Would tell us more.

@NilsIrl Yes, but let's assume it's our code causing that segfault somehow :-)

NilsIrl · 2020-02-21T01:44:30Z

@NilsIrl Yes, but let's assume it's our code causing that segfault somehow :-)

Yes, I was mentioning that so that someone didn't went looking for baseapi.cpp without ever finding it.

I can't reproduce on x86 (NixOS) with tesseract 4.1.0 (in addition to tesseract 3). I'd expect valgrind to give a backtrace.

~~Can you try to compile with linux/builddebug instead of linux/build and rerun with valgrind?~~ (nevermind, linux/build also gives a backtrace so the problem seems to be elsewhere.)

canihavesomecoffee · 2020-02-21T08:11:20Z

@jamoore5 The triggered assert looks similar to tesseract-ocr/tesseract#1670.

Can you try to explicitely set the LANG variable to "C" before running CCExtractor?

jamoore5 · 2020-02-21T12:33:21Z

I installed my packages for tesseract, and installed the binaries which seemed to have fixed the issue.

however I got the latest version

tesseract -v
tesseract 5.0.0-alpha
 leptonica-1.76.0
  libgif 5.1.4 : libjpeg 6b (libjpeg-turbo 1.5.2) : libpng 1.6.36 : libtiff 4.1.0 : zlib 1.2.11 : libwebp 0.6.1 : libopenjp2 2.3.0

and ccextractor still sees it as 4.0.0

ccextractor still sees it as 4.0.0

Could it be that you have both versions installed?

cfsmp3 · 2020-02-22T23:06:24Z

Labeling as medium because we can't reproduce.

shikharmn · 2020-02-27T07:10:13Z

Hey!
I would like to contribute to this issue. Can someone give me a direction as to where to start?

canihavesomecoffee · 2021-11-20T15:31:57Z

@cfsmp3 Closing this (reopen if you don't agree).

Original poster fixed the issue by installing tesseract 5.0 (this is also mentioned here: tesseract-ocr/tesseract#1670 (comment)).

I encountered this on the SP (Tesseract 4.0.0), and there it's fixed by exporting LC_ALL.

export LC_ALL=C

So either we can add this in our README/compilation guide somewhere, but there's nothing to fix in our code I think.

cfsmp3 added the difficulty: medium label Feb 22, 2020
