Convert existing Cintel CRI files to 3:2/3:1 compression?

PostTue May 15, 2018 3:58 pm

Since the new update is out, is there any way to convert exisiting uncompressed Cintel CRI files to 3:2 or 3:1 compressed files?

The SDK can do this no problem, the only tricky part is that the metadata contents from the older captures may not entirely adhere to the latest specification of the SDK. However, this should be fairly simple to debug through.

That said, the meta data should be able to be debugged easily enough, but you'd have to reverse engineer the compression. We have no motivations to do this and would prefer people jsut rescan, but if you have a large body of stuff, I'd recommend contracting a software engineer, but the libraries provided with the SDK can just as easily compress as decompress, so working backwards through what we do for decompress should lend itself to compressing all the same.

If there were overwhelming pressure from the community to allow for this upgrade of pre-2.0 files to post 2.1, we could consider adding this into the SDK examples as an --upgrade path. But I don't feel it's that big a deal and is just nice that we now finally have proper compression for Cintel.
