gdcl multiplexer create file with raw video not h264 - directshow

Question

i have created one graph as per below (i am using osprey card for input live stream)
(graphedit tool)
Osprey analog video in ----> GDCL MPEG-4 mulitplexer ----> File Writer (.mp4 file)
filesize is very big; even 5 seconds file have 80 mb size.
file doesn't get played.
when i see file detail in ffmpeg with ffmpeg -i,
it will give error like stream 0, missing mandatory atoms, broken header
below is ffmpeg response.
ffmpeg.exe -i "C:\Documents and Setti
ngs\Administrator\Desktop\mp4file\mp4file.mp4"

A multiplexer is used to multiplex different streams into a single file. Most of the time this will be an audio and a video stream. But a multiplexer does not encode audio or video. If you need h.264 video, you need to add a h264 encoder to the graph. For example you can use ffdshow for that.
See also wikipedia for the mp4 file format, H.264 video compression format, and other parts of mpeg4.
If you really mean to create an uncompressed .mp4 file, take a look at the official supported formats for .mp4. Uncompressed video is probably not officially supported. But even if it is, you also need support from both the multiplexer as the player. On his website Geraint Davies has added the following note:
Note: both mux and demux filters need a small amount of code added for
each media type that is to be supported. So far I have only added a
limited set of types. If you need other types to be accepted, please
get in touch directly It's likely that only a few lines of code will
be needed.
It is probably better to use MXF for uncompressed video.
