Dont want to add salt in this fight,
But on end note can anyone define what is "hack" ?
Because I get this answer to most of my approch.
Mine Analysed defination of hack in this community is that when other developers dont understand the code or when it is out of the general aproch, developers here call it hack. I might be wrong with my notion but I am asking to confirm.
this question was also creeping in my brain because none of Google defination match here:
cut with rough or heavy blows.
gain unauthorized access to data in a system or computer.
a rough cut, blow, or stroke.
an act of computer hacking.
Note: I dont want to hijack original thread, so please explain with refrence to this thread that which way of implentation wont be consider hack, which ways for ocr would be consider hack.
I am not speaking to make fun or insult, but it was far easy to implement ocr of dvbsub to get srt from dvbdub in ccextractor then here in FFmpeg because of unclear definition of hack. So I beg to make it clear today.
I really dont want answers in gurbish, like:
1) hack is that it would make difficult to developer or maintainer( until how do you scale difficult and easy, as per human brain is concerned difficult is what we dont understand which is non comparative )
The worst answer of hack is that: this is not the way I do in ffmpeg,
Since that is the reason you could not do it and new approch is needed.
