feature possibility? - skip over bad areas of a disc

[electronicsguy]

Hello,
I am wondering if it would be possible to implement a way to skip over bad areas for defective discs. I understand that ripping software wants to do a bit-by-bit copy of the original. However, in case of defective discs, this does not always work. Its definitely possible to get a replacement some of the times. Other times, I would rather just have the software skip over the dirty unrecoverable parts.

If a player can do this, I can't see a fundamental reason why ripping software should not be able to emulate the same behaviour. I guess it will involve some intelligence as to what should be the skipping distance, etc. (which may change as per format, the actual disc, etc). But can't a rudimentary version be implemented - say one that skips either by a absolute distance, or some absolute # of frames or something like that, and tries again. The end result would ofcourse involve an abrupt change in the movie, but that may be tolerable for some.

what do you think?

If this is implemented, I think it's critical to have it off by default, and requiring an option to be selected to enable this feature. Otherwise people may unwittingly be making rips with errors without knowing. And it should log the errors that it encounters. By default, I would expect MakeMKV to always do a perfect rip, and if it can't due to an error, I would expect it to stop.

sure. the option hardly seems to be the difficult thing here.
