Turning an InputStream into a SeekableByteChannel

Question

I am attempting to convert an InputStream to a SeekableByteChannel in order to stream in Open AL with LWJGL.

The current code is as follows thanks to the help of a demo online:

InputStream source = Thread.currentThread().
                         getContextClassLoader().
                         getResourceAsStream(resource);
ReadableByteChannel rbc = Channels.newChannel(source);

But I'm not sure, if at all possible, how I can seek through the OGG file in order to stream without converting it to a SeekableByteChannel

I'd be glad to supply more code if needed and thanks for any help in advance

Would you happen to know of any other way to seek the OGG file from within Java? Currently I read the whole which is not a good thing for a such a large file. — Alec French, May 08 '16 at 16:18
Presumably you'll have to open it as a [`FileChannel`](https://docs.oracle.com/javase/7/docs/api/java/nio/channels/FileChannel.html), which means opening it as a file rather than a resource, or perhaps converting the resource to a path. — Louis Wasserman, May 08 '16 at 16:22
In general, it doesn't work. If you give the concrete case, there might be a possible solution. — Jimmy T., May 08 '16 at 16:22

Take a look at apache commons compress library, you can construct a SeekableInMemoryByteChannel from byte array. And convert InputStream to byte array is very easy also.

InputStream inputStream; // input stream
SeekableInMemoryByteChannel channel = new SeekableInMemoryByteChannel
       (IOUtils.toByteArray(inputStream));
