Re: What compression is DataCodecCompress ?



See this:
http://developer.apple.com/documentation/QuickTime/APIREF/ datacodeccompress.htm


In summary - It does not use ANY specific compressor, it uses the one you supply.

Normally one would supply the zlib compressor.

Now does this one do zlib properly?  No idea.

If so, is it an apple-specific wacked out version of zlib ;)

I have tried to decompress compressed movie headers with php's zlib library to no avail :(

anyone know ?
