image decoding to a given memory area

bendeguy — Mon, 21 Aug 2006 20:26:08 GMT

Hello,

I would like to decode an MPEG4 frame to a specific memory area. I get the pointer from another part of the program, and I set it with the SetDest() function, but the LockInputBuffer()change the givenaddress. How can I decode to the given memory area?

Thanks in advance,

Bendeguy

Hello,

there is comment from our expert:

The VideoData class has SetBufferPointer method for using an external memory buffer. It may be called after calling of Init method. But there is one feature of this method method does an alignment of an input pointer. Sometimes it could lead to bugs.
