    This is BAD news as the camera is:

http://foscam.us/products/foscam-fi9821w-megapixel-wireless-ip-camera.html

    I am just an end-user and thus probably have little influence on them. I
will send them
the info that you suggest but I will be very surprised IF they respond. They
have their own ‘plug-in’ that works pretty well in IE and other apps.

    Are there any other possible work-arounds? Is possible that they are
using
MEDIASUBTYPE_AVC1 'AVC1' H.264(without start codes)? I did try
this(GetMediatype()), but
I have no decoders that will connect to that.....ughhhhhh.

Thanks very much for your help...

    Reading further on your site I see that you may need the SDP description
from my camera stream.
[...]

v=0
o=- 1365522147122142 1 IN IP4 192.168.1.2
s=IP Camera Video
i=videoMain
t=0 0
a=tool:LIVE555 Streaming Media v2013.01.25
a=type:broadcast
a=control:*
a=range:npt=0-
a=x-qt-text-nam:IP Camera Video
a=x-qt-text-inf:videoMain
m=video 0 RTP/AVP 96
c=IN IP4 0.0.0.0
b=AS:96
a=rtpmap:96 H264/90000
a=control:track1
m=audio 0 RTP/AVP 0
c=IN IP4 0.0.0.0
b=AS:64
a=control:track2


OK, the bug here is in your server - i.e., the camera; not the client.  The
camera (server) isn't including a "sprop-parameter-strings" parameter (in a
"a=fmtp:96..." line) in the SDP description.

Fortunately, however, I see that the camera (server) is also implemented
using our software, so it should be easy to fix.  Please tell whoever
developed your camera to:
(1) Upgrade to the latest version of the "LIVE555 Streaming Media" software,
and
(2) Either insert "SPS" and "PPS" NAL units at the start of the H.264 Video
stream (that it feeds into the "H264VideoRTPSink" object, or else change the
way that the "H264VideoRTPSink" object is created - to use one of the forms
of the "H264VideoRTPSink::createNew()" function that take "SPS"/"PPS" NAL
unit information as a parameter (either as raw binary NAL units, or a
"sPropParameterSetsStr" string).
