Hi,
My peers and I work with longform audio recordings (10-20 hours each).
We often need to sub-sample small portions (typically 1 percent) of many of these recordings in unpredictable ways, for various reasons.
Unfortunately, to do so, we must download entire recordings of ~1GB each, even if we end up using only 1% of each of them.
This can take hours.
My question is: how hard would it be to download specific ranges of bytes from a remote repository (given start/end cursors)?
Given that git annex can resume interrupted downloads, I assume there is already some code for readings bytes from a remote, starting a specific position in the file.
What would be the easiest way of doing this? Is it achievable via git annex' interface? Or would it require a change in git annex itself?
(My colleagues and I aren't proficient in Haskell and we can't really maintain binaries for the multiple platforms we work with).
If this requires a patch to git-annex, maybe this would be a feature of interest to a broader share of people?
Best,
