Hello all,
In DDK there are KSDATARANGE structures for MPEG1, MPEG2 and even
MPEG2TS . But there is no structure which supports MPEG4. I built a filter
with a output pin with KS_DATRANGE_VIDEO structure with Major type :
KSDATAFORMAT_TYPE_STREAM and subtype as MP42. But when i rendered the pin
its saying no inteermidiate filters not available.
There are directshow filters like Mpeg4 Decode DMO, Mpeg43 Decode DMO ,
Mpeg4s Decode DMO and Microsoft MPEG-4 Video compressor. I want to know
the major and subtypes supported by these filters. So that i can configure
my filter pin for that format. Even i tried with custom MPEG-4 filtes from
Elecard, DivX and Dicas. Still i am not able build the graph.
So i have following questions:
1. Is there any support for MPEG4 streaming in directshow.
2. Which data range structure should be used for MPEG4 SL streaming.
3. What should be the major and subtype of the pin.
4. Is there anything extra should be mentioned in the data range structure
so that directshow should understand and add mpeg4 related intermidiated
filters.
Any inputs and pointers on above queries are highly appriciated.
Waiting for ur reply.
