I'm writing a live source filter,the filter push data from a capture card to
next filter.I create the filter using "CSource" and implement out pin using
"CSourceStream",I also implement "IAMFilterMiscFlags" in filter,but I don't
know is it a "live source" filter,what interfaces I must implement?Is there
any difference between live video and audio source fillter?

Serendipity :)

I hope that the OP posts up some observations on using this sample. He or
she comes to the community to ask questions but, AFAICT, hasn't contributed
much here:

Hi Guys ,

I am in same boat - implementing DS user mode wrapper over some camera
private API.
So far everything looks good but I have a problem :

- The "camera" (source filter) works fine with graph editor and AMCap
application but wan't appear in WindowsXP's "Windows Movie Maker" as a source
(actually I have it sometimes "pop" up for a split of the second and then
disapear).
Same thing happens with the VCAM sample filter from the downloads page, so I
guess it's not only my problem.
My personall bet is that it need some other interfaces exposed besides
IAMStreamConfig and IKsPropertySet but which ?

Any ideas ?
