Multi-VPP crash issue

Hello:

       I'm using intel hw to encode h264 video recently, and i found that the program will always crash. after serval week's debug, i found it's caused by VPP, and i wrote a small test program,  only use VPP, after serval hours or 1 or 2days, it will crash in libmfx32.dll. my use case is:

       1. malloc memory for input YUV

       2. read YUV data.

       3. malloc memory2.

       4. copy YUV from memory to memory2.

       5. malloc memory3 for output YUV.

       6. attach memory2 and memory 3 to input and output surface.

       7. call RunFrameVPPAsync

       8. call SyncOperation

       9. free all the memory.(in my real environment, i need always malloc and free memory like this)

       10. loop it forever.

        i have upload all the test solution, for input YUV, i use 1920*1088(for multiple of 32)&NV12, so you can use any YUV with this format to reproduce it.

Hello there - 

"ncode h264 video recently, and i found that the program will always crash" --> What encode application did you use? Did you use sample_encode from samples or simple_encode from the tutorials?

"caused by VPP"--> Can you please run the tutorial applications such as simple_4_vpp_resize_denoise and let us know if you are seeing similar behavior (VPP crashing I mean).

In general, we highly recommend you use our samples and tutorials applications as starting points. For simple encode test, you could use simple_3_encode tutorial or its variants, for simple vpp operations test, the sample I mentioned above. If you want to test multiple encodes and vpp, you can use the sample_encode and sample_vpp samples.

Let me know if you can reproduce the issue you are seeing with the samples/tutorials I mentioned above - that would be greatly helpful.
