as a renderer.

Please write in English with proper capitalization and punctuation.  Is
that difficult for you?

As I wrote before, the types supported are going to be different based on
the renderer you choose and the types that the graphics card supports.  I
already suggested a solution:

"Or alternatively, why not just use MEDIASUBTYPE_RGB24 with the sample
grabber and convert the frame to the destination type yourself after
grabbing it?"

These conversions are not hard the algorithms are easy to find with Google..
Alternatively, you can use a third-party library like the Intel
Performances Primitives.

When i use VideoRenderer and when i set different MEDIASUBTYPE on
sample grabber filter it is converting the frames into the format what
i set on input and output pin of sample grabber its working fine.

The problen is when i use VideoMixingRenderer and when i set the
MEDIASUBTYPE, when i set YUY2 it is converting the frames into YUY2
and when i set UVY it is converting the frames into UVY , but when i
set RGB24, RGB555 or RGB565 it is not converting frames into RGB24 or
RGB555 etc, instead it is using colour space converter as intermediate
filter and coverting frames only into RGB32 format on both input and
out pin of sample grabber for all above RGBxx format.

Using VideoRenderer all formats can be written into file, but using
VideoMixingRenderer only YUY2,UYVY,RGB32 formats are written.

Now i want to write RGB24,RGB555,RGB565 into file using
VideoMixingRenderer give me suggestion or any sample code.
