I am developing videoconference application. Please help me to understand how many sessions can be processed simulteniously. Request of Decoder->QueryIOSurf() returns NumFrameMin = NumFrameSuggested = 17 for 640x480 frame (also 7 for 1280x720 and 9 for 320x240). The same values passed to callback Alloc() when Decoder->Init() is called. Any different values I am trying to pass with Request.NumFrameSuggested leads to Decoder->Init() error. So, 1 decoder session required to allocate 17 * 640*480*1,5 = 7833600 bytes and 10 simultaneous sessions will require 78 Mb. But I have only 64M of video memory on my PC. Is it real limitation of 8 sessions in this case? What happened when I shall try to alocate more video memory than available? Is any way to reduce the number of allocated frames for decoder session?
