Numerous Intel decoder for d3d9.dll crash

Hi,
I build h264 decoder sample is successful.
When i use a lot of (e.g 4) h264 decoder it crash, error message show "d3d9.dll errorr" on "memory_allocator.cpp"
line 【if (GetFrameHDL(response->mids, (mfxHDL *)&handle) == MFX_ERR_NONE)"】

If use 4k video can run on 4 decoder not crash,
use 1080p video can run on 10 decoder not crash.
but too many it will crash.

This my system info:
OS : windows 8.1
CPU : i7-4720HQ
RAM : 8G

Link structure like :
[RTSP Filter (H264) ] -> [Intel H264 Decoder(Build)] -> [EVR]

Hi Joe, 

Can you please tell us which driver version you are using? what Media SDK version do you have installed on your system? Can you send us a reproducer to test the application at our end. I tried using sample_multi_transcode in which you can do N decodes, I can easily go till 30 decode sessions on an i5 4th generation system with a little different Integrated graphics card. 

Can you please confirm output of below experiments to narrow down the problem here -
the behavior if you d3d11 instead of d3d9 implementation. 
the behaviour without rtsp filter, please take local file available and test the decoder. 

Let us know your finding to debug this issue in detail. 

Thanks,
Surbhi

Hi SURBHI,
Thank you for your answer!

I meet new question!
The project activex can read a list build [rtsp->decoder->renderer], it have one or more rtsp video on one time.
i tried use google chrome it not crash, but use ie over 4 rtsp video it crash!
Use the same pc, same rtsp video ,same config.
How do I debug? or How do I fix?

Thank
