No. I couldn't even find out if it was called Msft Multimedia Services or Msft Metadirectory Service. It seems to be built into the Win NT media service components.

We have a 2000 file server here and I personally hate the frigging thing. Microsoft should take a clue from most other operating systems in the world and seperate the OS into discrete chunks. There's the file system, and the windows system, and the kernel drivers, and the device drivers, and in most sane operating systems these things are discrete entities to some degree. Not microsoft! They make what operating systems designers call a 'monolithic' kernel look like a creme drop next to a giant wad of cotton candy. > P.S.

Mystery solved!! It's not my code.It's Microsoft!!! On a lark, I tried the same code on another system. My development system is Windows 2000. I tried it on a Windows 98 machine and VOILA, I get the request. The Illegal Request error must be coming from within the bowels of Win2k.

A little...
I can't look at it in depth tonight, but here's a snippet of code from
my stuff. It's unlikely that this will solve your problem, but it's all I
have time to do *right now*. I'll try to dive in later. This is all from
the windows media side of things, not the socket side of things.
ECS(data->port_cs);
sprintf(szUrl,"http://127.0.0.1:%i/%i",*data->port,key);
LCS(data->port_cs);
MultiByteToWideChar(CP_ACP,0,szUrl,-1,wsUrl,256);
// create the WMA reader
hr = WMCreateReader(NULL, 0, &comReader);
if (hr!=S_OK) {ODS("Could not get a reader\n");}
// open the reader, with cNoise->OnSample as the callback
ResetEvent(data->hWait);
hr = data->noise->QueryInterface(IID_IWMReaderCallback, (void **)
&comCallback);
if (hr!=S_OK) {ODS("cNoise couldn't be a callback\n");}
if (hr == E_NOINTERFACE)
{ODS("No Interface? (hmmm)\n");}
if (hr == REGDB_E_CLASSNOTREG)
{ODS("Class not registered. (oh fuck)\n");}
if (hr == CLASS_E_NOAGGREGATION)
{ODS("Class can not be aggregated. (huh?)\n");}
hr = comReader->Open(wsUrl, comCallback, 0);
if (hr!=S_OK) {ODS("Could not open the reader\n");}
WaitForSingleObject(data->hWait, INFINITE);
data->hWait gets set by the object data->noise, which implements the
callback, which is called by the system during opening:
STDMETHODIMP CSound::OnStatus(
/* [in] */ WMT_STATUS Status,
/* [in] */ HRESULT hr,
/* [in] */ WMT_ATTR_DATATYPE dwType,
/* [in] */ BYTE __RPC_FAR *pValue,
/* [in] */ void __RPC_FAR *pvContext)
{
// ODS("OnStatus\n");
switch (Status) {
case WMT_OPENED: ODS("OnStatus(WMT_OPENED)\n");
HANDLE hWait;
hWait =
OpenEvent(EVENT_MODIFY_STATE,FALSE,"windowsmedia_open");
SetEvent(hWait);
break;
there are a bunch of other cases that you should consider processing,
and a similar function:
STDMETHODIMP CSound::OnSample(
/* [in] */ DWORD dwOutputNum,
/* [in] */ QWORD cnsSampleTime,
/* [in] */ QWORD cnsSampleDuration,
/* [in] */ DWORD dwFlags,
/* [in] */ INSSBuffer __RPC_FAR *pSample,
/* [in] */ void __RPC_FAR *pvContext)
{
// ODS("OnSample\n");
// ODS("on sample\n");
struct sound *s;
s = (struct sound *)CoTaskMemAlloc(sizeof(struct sound));
unsigned char *in;
pSample->GetBufferAndLength(&in,&(s->size));
which is called for each sample.
If this helps at all, tell me. If it doesn't help at all, tell me that
too. Oh, ODS is a macro for outputdebugstring, and ECS/LCS are enter
critical section and leave critical section. Neither have any real effect
on the code, at least not the part you're trying to understand.

RE: Support for other file formats
Let's sync up. Goal: Provide an arbitrary byte stream to the IWMReader object in the Windows Media Format SDK.

Let's talk about what you mean by use HTTP. When I say, HTTP, I'm getting a socket from the os, throwing together a header, sending the header, then sending the binary data. I'm essentially assemblng a web page and sending it out. Is this what you mean by HTTP? Or is there some API you are using that I don't know about? Here's my header, BTW, I recall I had some trouble making WMA happy: " HTTP/1.1 200 OK\r\n Server: Stupid-Loopback-0.2\r\n Content-Type: audio\r\n \r\n " All newlines are for readiblity only. > If I use an external host, to monitor packet transmission, as in > "http://192.168.1.250:portno/file.wma" I don't see any packets, but I > eventually time out with the NS_E_INVALID_REQUEST error. Uh, hmm. There's a good code sample in an SDK somewhere, one much of my code is based on. It's C:\WMSDK\WMFSDK\samples on my system, you're looking for windows media format SDK - probably from microsoft. There's also a DLL that you have to link to in that heirarchy as I recall. > I am sure that I am missing something fundamental and simple. Any guidance? Let's try to get on the same level here. The samples above are good and have source code. I don't remember having any of the errors you are describing. I wish I could send you my code but I wrote it for a company and it can't go out - but if you're writing for FreeAmp then I could look at yours. ___ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev
RE: Support for other file formats
OK, I'm confused now. If I try to use the MMS protocol as in "mms://localhost:portno/file.wma", I receive a packet but do not know how to decode it and respond. If I use HTTP, as you suggested, as in "http://localhost:portno/file.wma", I DO NOT receive a packet but get error 0xC00D002B or NS_E_INVALID_REQUEST. If I use an external host, to monitor packet transmission, as in "http://192.168.1.250:portno/file.wma" I don't see any packets, but I eventually time out with the NS_E_INVALID_REQUEST error. I tried the same things with the Microsoft sample apps and the results were consistent. I do get a packet when I use the address in my browser. I am sure that I am missing something fundamental and simple. Any guidance? Ed Patriquin ___ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev

HTTP. The big thing that got me, and might be getting you, is that the WMA code gets the file twice. It connects to the socket the first time, reads about 20 to 40 k bytes, drops the connection, and starts over, reading the whole file from the beginning the second time. ___ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev

I did an experimental version based on 2.06. The problem I ran into was the need for a temporary file. I couldn't find a way to hook up the WMA classes to the streaming input. The WMA classes seem to be designed to only work with files. I didn't make it more widely available because this limitation made it inconsistent with FreeAmp's architecture.
