[fpc-pascal] Pipe vs Memory buffer.

[fredvs]

Hello Silvio:

Yes, we are on the good way.
Following your advice, here from https-url-opus the result of :

var
  BufferURL: tbytes;

  setlength(BufferURL, PipeBufferSize);
  CreatePipeHandles(InHandle, OutHandle, PipeBufferSize);
  InPipe := TInputPipeStream.Create(InHandle);
  OutPipe := TOutputPipeStream.Create(OutHandle);
  httpget := TThreadHttpGetter.Create(url, OutPipe);
  InPipe.Read(BufferURL[0],PipeBufferSize);
 
  writeln(tencoding.utf8.getstring(BufferURL));

You may note that some opus infos are there and seems to be the header.
Sadly, op_test_memory(BufferURL,PipeBufferSize, Err) gives this error:

error -132: A purported Ogg Opus stream did not begin with an Ogg page, a
purported header packet did not start with one of the required strings,
"OpusHead" or "OpusTags", or a link in a chained file was encountered that
did not contain any logical Opus streams.

But there is some light, we will win.
