HEVC HW decode on haswell

CBill2 · ‎01-18-2016

Hi I have a problem when i use HEVC HW decode with plugin was "33a61c0b4c27454ca8d85dde757c6f8e".

The follows is my code.

MFXFrameAllocator* m_pMFXAllocator;

.....

sts = m_pMFXAllocator->Lock(m_pMFXAllocator->pthis, m_OutputSurface->Data.MemId, &(m_OutputSurface->Data));

......

sts = m_pMFXAllocator->Unlock(m_pMFXAllocator->pthis, m_OutputSurface->Data.MemId, &(m_OutputSurface->Data));

MSDK_BREAK_ON_ERROR(sts);

The first frame was OK, but the next frame it was locked on " m_pMFXAllocator->Lock" function, it can not keep on next code. It was like dead locked on " m_pMFXAllocator->Lock" function.

PS: I use HEVC HW Plugin = "33a61c0b4c27454ca8d85dde757c6f8e", it was OK on init HEVC HW decode.

In addition it was running normal when using SW decode with plugin was "15dd936825ad475ea34e35f3f54217a6".

The follows picture is my computer.

Thank you for your help.
