Additional information

The sample present in the above link has hard subtitles embeded in the video and ccextractor is able to extract them till 11% and then it abruptly is killed. I was unable to figure out the reason for the stopping of the program.

It's probably due to memory constraint, did you try it in an environment with more memory (it executes fine on my machine)?

I'll try it and report back.

Though that makes me wonder, are there rooms to improve the efficiency
there?

I'm kind of naive at image processing but I think it is strange that one
gigabyte couldn't suffice.

@saurabhshri I'm closing this since it's resource-related but, nevertheless, it would be amazing to see if we could make this feature less straining 😃
