Remarks

You must set the offset of the requested media sample based on the properties of the streamer i.e. the streamer supports time based seeking allocator. To retrieve the source properties, call IAsyncReader2::GetCapabilities. If the allocator is based on time streamer supports time-based seeking, set the offset from the start time of the stream and set the time in the IAsyncReader2::SetCurrentTime B83A386C-0EF8-418E-A488-5CAFBB566603method. If the allocator is based on position streamer supports byte-based seeking, set the offset in bytes from the start of the stream.

You can retrieve the sample from this position by calling IAsyncReader2::GetNext.
