"Reverse engineering x264" program for video restoration
I think it could be built like this:
Just like for x264 encoding using different parameters to obtain high quality compression, this "reverse enginereeng" software must to have possibility for the user to enter various parameters in command line to be able to obtain as a result a source as close to an original . Please tell me what you think about that (I have a name for this program : RevX264 ) Last edited by dadix; 20th June 2012 at 09:36. |

Yes, something like that and i think is possible to "unrar" or "RevX264" to rebuild a source from a mkv (with x264 encoding or somthing else) but must to do reverse enginereeng for this compressed video.

If you know the result is 7 (compressed video with x264) and is obtained with x-3 (this is x264 encoding) with reverse enginereeng must to obtain original files x. Why something like that may not be possible ? Last edited by dadix; 20th June 2012 at 10:43. |

Here's an analogy. I have two numbers A and B. I give you only the average (A+B)/2. No matter hard hard you want it, and no matter how hard you try, you cannot recover A and B using any algorithm. (You can try making an astronomically unlikely guess, however.)

@dadix
If you genius for avisynth, write a script to remove all kind of mosaic from all kind of videos. If you can, that's not problem and you don't need any other program But i'm afraid that is not possible. Last edited by bxyhxyh; 21st June 2012 at 06:47. |

I think the decoder function is limited and refers to entropy data. Reverse engineering go beyound that , to another level, and takes care of handling the coefficients to obtain spatial model and then getting forward to handling and obtain temporal model from residual data

http://www.cse.msu.edu/biometrics/Pu...35fenhance.pdf I put this information because i think the ideas and formulas from this document can be adapted for vectors in reverse engineering technique for missing blocks and adding details. Last edited by dadix; 21st June 2012 at 16:35. |

Well, I'd be interested in seeing what you'll get out - if you're going to achieve any results. (I doubt you'd release anything if you didn't, which is why I state this for some reason. ;p)
But as you've seen, we're all pretty sceptical on whether that's even possible. If you're determined on trying - however, please go ahead! (Trying has never hurt, has it now. :-)) |
