I try to use vpp resize to 1280X720 before hevc encoding,but all failed when my apps run as service on win2012R2. return error: MFX_WRN_DEVICE_BUSY = 2, /* the HW acceleration device is busy */ the same test case, use avc encoding can work normal and hevc run as command can work also, and resize to orther size also success. Test gpu machine info: Cpu: Intel(R) Xeon(R) CPU E3-1585 v5 @ 3.50GHz Memory: 2 X 8GB DDR4 Operation System: 2.Windows Server 2012 R2 x64 MSS Version: MediaServerStudioProfessional2017
it can be reproduced with MSS2017 Samples for Windows v188.8.131.52
Remind：sample_encode.exe must run as service and using system memory, d3d11 without this issue.
