You can't directly access the internal data once it enters the pipeline. The compression method I'm using pipes the data directly to a FileSink, and > it works (the decompression method also works if I do that), but when I try > to get the uncompressed data in memory trough an ArraySink and then pass it > trough a file stream, it seems to fail at some point.

A custom filter will allow you to perform additional processing or transformations, just like a HexDecoder or StreamTransformationFilter. Also see https://www.cryptopp.com/wiki/Filter. A ChannelSwitch is like the Unix tee command. It splits the output stream into two streams. Also see https://www.cryptopp.com/wiki/ChannelSwitch. Its also worth mentioning... If you want to have two logical chains instead of one big one, then use a ByteQueue rather than an Array. We provided an example of using ByteQues recently on Stack Overflow at http://stackoverflow.com/a/42820221/608639. But I recommend the custom Filter or ChannelSwitch before using two different chains glued together.
