What happens here is that libsoup downloads the compressed data and extracts it using SoupContentDecoder, but returns the size of the specified Content-Length instead, thus the size of the uncompressed data differs from the actual reported size.

I don't think this is the right fix. By doing that you're increasing the http transfers potentially by a lot since the server won't compress data. The problem is that you cannot assume that you could know the actual size of the data after receiving the http headers. It is not true for compressed data as you said but it isn't also true for "Transfer-Encoding: chunked" or for responses without encoding (ended when the connection closes).

So my advice would be to try to reorganize the gstreamer code in order not to depend on the size of the data, not sure if that's possible tough.
