corrupt dv-file

[pdehon]

While capturing video to a dv-file my application crashed. As a result the dv-file cannot be read by Windows Media Player. Is there any tool to repair dv-files?

Thanks in advance,

Peter

Couldn't you just transfer it again? Best thing to do to avoid any possible problems.

Does Gspot 2.70 recognize it as a DV file? Also you could add a DV codec, like the Panasonic Codec, and open it with VirtualDub and see what it makes of it. VD has a few tools to repair most AVI type files, including DV.

But just because a DV transfer stops, that shouldn't corrupt the file. I think you may have other problems. What 'application' were you using for transfer?

Unfortunately it does. If the underlying DirectShow framework is used (most likely) then the AVI header doesn't get written until the capturing is correctly stopped. If the capture app crashes then the required stop doesn't occur. (I ran into this "feature" some time ago, though not due to crashing).

If the size of the corrupt AVI file is less than 1GB, you can use a hex editor to paste a good header from another file. Some manual editing is then needed to correct the frame count etc. Beyond 1GB, it gets more troublesome. It such a case, recapturing (if possible) is the most painless route. So, you might as well recapture irrespective of the size.

Thanks, JohnnyMalaria. I guess I wasn't thinking of a crash, just a stoppage. That sounds like it would be tough to fix, especially with large DV files.
