I have 3 version MMS  patches:
(1) you sent to me several weeks ago.
I rip out mmsh code without functional modified based on this patch focusing
on mmst.
I just copied the related code to one file, and write it like URLProtocol
implemented files.
so my primary version mmst.c is huge because lots of mms state to be
maintained.

(2) from this link
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-January/020937.html
(3) from this link
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-August/033812.html

(1) and (3) almost are the same code, but (2) has a little difference with
the others.

As to getting response from the server:
(2) do something like this:
 read_bytes(mms, mms->incoming_buffer, len) ----->then call
url_read(mms->mms_hd, buffer, length_to_read);

however (1) and (3) do something like this:
get_buffer(&mms->incoming_io_buffer, mms->incoming_buffer, 8)
they get data directly from incoming_io_buffer, so the returned result is
error.

I'll modify the code according to (2) and try it again.
