If you are passing along AVI frames from an AVI file, and you hope to be

MEDIATYPE_Stream, and your subtype is MEDIASUBTYPE_Avi.

According to you I have set the majortype and subtype but I am
confused what are the values to set for VIDEOINFOHEADER structure, and
also BITMAPINFOHEADER values of this structure.

VIDEOINFOHEADER and BITMAPINFOHEADER are only used by MEDIATYPE_Video.  You
do not have video data, you have a compressed stream.  For
MEDIATYPE_Stream, you would use FORMAT_None.

What are you REALLY sending along to the graph?  Are you just reading an
AVI file a few kilobytes at a time, and sending that raw data downstream?
If so, then MEDIATYPE_Stream is correct.  The graph builder will insert an
AVI parser next, and that parser will figure out what the real audio and
video formats are.

Yes Sir, I am reading the data from file and pushing that raw data to
downstream filter, I have observed that if I read the file using
AddSourceFilter method then the connection between source and AVI
splitter is connected but if I use my push source filter then no
connection is taking place and also set the major type what yooooy
told and code is

p_mediatype->SetSubtype(&MEDIASUBTYPE_Avi);
p_mediatype->SetFormatType(&FORMAT_VideoInfo);
p_mediatype->SetType(&FORMAT_None);
p_mediatype->SetSampleSize(p_vid_info_hdr-
bmiHeader.biSizeImage);
p_mediatype->SetTemporalCompression(FALSE);

Still connectin is not taking place please tell am I setting the
correct format or not.
