LZO Decompression Buffer Size

I am using MiniLZO on a project for some really simple compression tasks. I am compressing with one program, and decompressing with another. I'd like to know how much space to allocate for the decompression buffer. I am fine with over-allocating space, if it can save me the trouble of having to annotate my output file with an integer ...

Reverse Engineering: How do I identify an unknown compression method?

Hi, I'm with a group of modders attempting to reverse engineer and mod a Blu-Ray player. We're stuck because the firmware code seems to be compressed, and the decompression code is nowhere to be found. Presumably, the decompression is handled by hardware. My question is, with only the the compressed output, how do we determine what typ...

How do I uncompress a file compressed with fusecompress/lzo?

I had mounted a fusecompress of directory compressed/ at fusecompress/ I copied a large file (several GB) to the fusecompress directory (ok, I mv'd it). The compressed file in the directory compressed/ is length 1,221,396,660. However, I cannot remove/uncompress the file. fusecompress has a memory error: "Cannot allocate memory". Is the...

Are there benchmarks of Java LZO vs. Deflate vs. Gzip available?

The (very outdated) page for LZO contains a link to a Java implementation. There is also the vague promise of "New ... Java ... interfaces ... sometime in the near future.", but I believe that has been there for a few years. This makes me think that the old LZO Java implementation may have been slow. Are there any benchmarks measuring...

Can libraries licensed with GPLv2 be used in proprietary applications?

I'm interested in included LZO compression into a currently closed source application. Currently LZO is licensed with GPLv2, but i'm confused as to if I need to also open source my application if I use their libraries. I'm not changing their library in any way. ...

using lzo library in c++ application

I got lzo library to use in our application. The version was provided is 1.07. They have given me .lib along with some header file and some .c source files. I have setup test environment as per specs. I am able to see lzo routine functions in my application. Here is my test application #include "stdafx.h" #include "lzoconf.h" #includ...

C# LZO Library and Experience

Anyone have experience with a C# LZO compression/decompression library? LZO.NET (at http://lzo-net.sourceforge.net/ ) looks pretty alpha QuickLZ (at http://www.quicklz.com/ ) isn't stream-based and I need to compress files as they're generated and don't want to buffer the whole file in memory MiniLZO (at http://www.codeproject.com/KB/r...
