I'm trying to display 4 or more mpeg4 streams at the same time by using umc's DX_VIDEO_RENDER option. I modified the simple_player example in the ipp_samples to render 4 streams. Simply I copied all the necessary code blocks and changed to work with 4 different streams. But I couldn't render 4 streams with DX, except first stream, the others rendered as BLT_VIDEO_RENDER. As a result of my deeply debug sessions i found that the line 263 on the dx_drv.cpp was not succeded for the 2. or 3. streams.
I'm stuck at this point and have no idea about what I do to get over this problem.
