Feature Request: unzip a specific byte range

[zkrige]

I want to be able to extract a portion of a file in the zip archive. My specific use case is reading a video file from the zip, I only want to fetch specific chunks of data from the video file while playing the video

If you mean seeking to a specific file position and then read a chunk, with Objective-Zip this is not yet possible. It may be possible with the underlying MiniZip library.

What is possible now with Objective-Zip is buffered reading, i.e.: you don't need to extract the file as a whole, you can expand it in memory and consume it segment by segment. Check out this section of the README for an example.

Yeh, I currently expand in memory and pass the data back as needed. But at the moment I have to start at 0 for any given file in the zip. It would be nice to be able to read a chunk from a file in the zip and return that. I'll take a look at whats required and see if i can implement it. I might do a PR
