I have tested the intel media sdk MPEG-2 encoder which i got when i installed this sdk in my XP system. My processor is intel core 2 duo. At the last stage of installation it shows a message that you have to manually enter environment variables for DIRECTSHOW_BASECLASS. Is it for Including Header files of base class or for Strmbasd.lib?
any way i set it manually.
The problem is using Graph edit (atool of platform SDK), i cant connect the out put pin of Web cam or any video card (which is installed ) to the input pin of intel media sdk MPEG-2 encoder (or any of the encoders AAC or h264 etc). Can you guide me what i need to do or flow of graphs to test filter with graph edit?
I tried a Raw video uot from the wmv file ->Intel video Vc decoder -> intel video MPEG-2 encoder->filewriter. Worked. but size got as 10 times. So please guide in this connection.

Hi prasanthkumarpa,
Thanks for checking out the MediaSDK. I must first say that the MediaSDK is not supported on Windows XP. Please see the FAQ that is posted on this forum. The MediaSDK MPEG-2 encoder DirectShow filter's input pin accepts: MEDIATYPE_VIDEO, FORMAT_VIDEOINFO2 with a subtype of MEDIASUBTYPE_YV12. What is the output pin upstream trying to connect with? The input/output formats for the sample filters are all documented and can be found in the "doc" directory of the package. If you can provide a bit more information, I'd be happy to assist you - but remember XP is not supported.
Thanks!
Eric

Also, regarding the question about DSHOW_BASECLASSES_PATH variable, it is required to build sample DirectShow filters source code and is used for both include and lib paths of Visual Studio solution.

Nina,
What you said is not true. In GraphEdit,Intel Media SDK sample decoder/encoderreportthat they supportMEDIASUBTYPE_YV12 as input/output. Whatever the document states, information from filter binary is always right, isn't it?
So I thinke Intel Media SDK supports MEDIASUBTYPE_YV12.

Actually, what is reflected in filters' properties in GraphEdit is also a mistake, we will fix it in the next release along with documentation. If you try to connect Media SDK filters in chains you'll see that decoders produce NV12 subtype at output and encoders would accept only NV12. So, MEDIASUBTYPE_YV12 is not supported, for sure :)
Regards,
Nina
