Additional information
Hello, I've tried using the program to extract burned-in subtitles from a .mp4 movie, but it seems to always show me this error: "Not enough memory to initialize Tesseract!" Is there any solution known for this issue?
It seems your computer doesn't have the power to run Tesseract. Therefore there isn't any issue with CCExtractor but with your computer running it.
Could you please post complete logs along with procedure you followed to compile CCExtractor?

I doubt it, as my PC has 16GB.

I did not compile CCExtractor, I downloaded the binaries (GUI and command line programs) and later the installer itself. None of them worked.. All I did is open CCExtractor, selected my file, selected "With OCR" below, ticked "Perform burned-in subtitle extraction", started and received the mentioned error.
This is also happening on Ubuntu 18.04 with ccextractor compiled from master using the tesseract from the normal repos. If I manually extract images using ffmpeg and run tesseract then there is no complaining about memory on my 8GB Dell XPS laptop.
Now my C++ is almost non-existent but looking at the tesseract code looks like it may have nothing to do with memory at all. https://github.com/CCExtractor/ccextractor/blob/master/src/lib_ccx/hardsubx.c#L238 Assumes that any non-zero return value means "Not enough memory to intialize Tesseract" but I don't see anything in https://github.com/tesseract-ocr/tesseract/blob/master/src/api/capi.cpp#L241 or https://github.com/tesseract-ocr/tesseract/blob/master/src/api/baseapi.h#L189 that suggest that non-zero is guaranteed to be memory related. It simply says:
- Start tesseract. Returns zero on success and -1 on failure.
- NOTE that the only members that may be called before Init are those
- listed above here in the class definition.
I may well not be looking at the right place but it seems to me that this could well be something other than insufficient memory.
@saurabhshri , do you have any ideas about this? Am I completely wrong in my interpretation of the code?
@AntonOfTheWoods No, you're not. It's not your machine. It has been reported previously, but they were able to solve it. Happy debugging :)
OK let's try to figure this one out... @Aradmey first, does it happen with all files or just some, or a specific hone? Can you share one?
Have you tried in 0.87?
@Aradmey , was it you that was able to solve it or did you abandon CCExtractor?
@cfsmp3 , I am using master rather than an official release version (like 0.8.7) so I can get support for tesseract 4 (the version available on Ubuntu 18.04). The git log suggests I need the HEAD of origin/master for that. Could this be simply a matter of tesseract 4 not being fully supported yet? I have also tried with the latest tesseract version from https://launchpad.net/~alex-p/+archive/ubuntu/tesseract-ocr and have the same error. Is it worth trying to get tesseract 3 installed and using 0.8.7? Thanks.
Give tesseract 3 a try indeed... in any case it's going to be faster, tesseract 4 seems better handling handwritten stuff but for our use doesn't seem like a great upgrade. On Fri, Nov 30, 2018 at 6:30 AM Anton Melser [email protected] wrote:

@Aradmey and @cfsmp3 , I can confirm that manually compiling tesseract 3.05 on Ubuntu 18.04 and compiling ccextractor at master and pointing to the tesseract 3 gets rid of the error. I definitely think the error message could do with some improvement though!
I'm completely new to CCExtractor. I'm encountering the same issue when running 0.87 on Windows. My steps to reproduce:
-
Install the Windows installer for CCExtractor on Windows 10.
-
Run the GUI version with the following options:
C:\Program Files (x86)\CCExtractor\ccextractorwinfull.exe --gui_mode_reports -out=srt -bom -latin1 -hardsubx -subcolor white -conf_thresh 60 [+input files]
When I click the "Start" button, I get the message "Not enough memory to initialize Tesseract."
Could this be a problem with Windows support for Tesseract? I noticed that the Windows version seems to be lagging behind the Linux version.
For what it's worth, I'm trying to use CCExtractor to make some HBO shows more accessible. The show "My Brilliant Friend" is spoken in Italian and has burned-in subtitles in English, but those aren't accessible for for English-speaking blind users. Details below. If there's a way to OCR these subtitles, that would be completely amazing.

Same issue as above, is there any solution yet? Run with different options? Many thanks.
Same issue. Windows 10, Tesseract3 is installed and in my System PATH.
@DaniGTA I guess that this problem was already fixed by #1083 that changed the way Tesseract is initialized. Previously if for some reason Tesseract was not initialized, you were getting a memory error. #1083 updated the way Tesseract is initialized to be more stable. Anybody who had this error - kindly ask you to check it again with CCExtractor's master.
Hello,
I was having the same problem (error message while running 0.87 GUI - "Not enough memory to initialize Tesseract") so I cloned the master and compiled on Windows 10 using Visual Studio 2019 (Community) and the instructions given here. However, when I launch the new GUI I am seeing the following message:
I have tried compiling with both the Debug and Release configurations. Has anyone else had this problem or have an idea why the library can't be found?
Closing - this seems fixed. Feel free to comment if anyone is having this problem in current master.
