Embedded Subtitle Extraction From Entire Library as scheduled Task?

[dovedescent7 3]

Ok i just spent 45 minutes googling how to do this and didn't get a clear answer. I am a paid emby subscriber for 1.5 years. 

 

I would like to schedule a task where emby extracts every embedded internal subtitle from every movie/show in my library then convert it to a nice .srt file which will sit next to the video file it just extracted from. 

Is there a way to automate this WITHOUT using Opensubtitles.org? 

 

Thanks 

 

EDIT. The OP in this thread below shares code to input in emby to Automate this process(I beleive). Is this safe to do? And hopefully create a task for this? I just get concerned about malicious code....

the "easy" bit is extracting the sub tracks from the video - ffmpeg/mkvmerge etc can be easily scripted to do this

the "hard" bit is converting the subs to srt - some are easier than others

text based subs ass etc should be easy enough

the challenge is the "picture" based subs which need converting via OCR etc - this is very hit and miss as its dependant on the quality of the video/text images and the font used - doing this by hand for the occasional video via SubTitle Edit - you get a huge variation in accuracy of the OCR - 90% i have done have required manual editing after OCR - for miss identified text from the subtitle images created for blu-ray/dvd players etc. This gets more complicated the more languages you want to extract/keep/convert etc

Scheduling via task scheduler or cron etc is straight forward as emby does not provide you a way to do this currently

Dont think its impossible to do - just not sure the outcome is going to be fully automatic and require you to check each srt produced from a pgs sub etc
