Our test environment is the MSS 16.5 PV1 and the decode indeed can't 
work in the system memory.

You are not passing anything to av_hwdevice_ctx_create(), so it will be going through exactly the same set of possible device nodes as ffmpeg did and will therefore fail to find the device in exactly the same way.
> So, to properly fix the problem I think you are having (but correct me if this is wrong), you really want the -qsv_device option added to ffmpeg to apply to this case in libavcodec as well?  That is, we get the qsv_device in ffmpeg into libavcodec somehow and then use it with the code below.  (Patch itself implementing that looks mostly fine, but I would prefer to get the methodology resolved first.  Similarly for the matching patch to the encoder.)
yes, you are right!  We do need to add the qsv_device for the 
encode/decode to choose a device handle.  The user can assign the device 
using the
below command:

/./ffmpeg -qsv_dev device -c:v h264_qsv -i in -c:v h264 output.h264/

/ ./ffmpeg -c:v h264 -i in  -qsv_dev device-c:v h264_qsv  output.h264/

Using the qsv_dev inorder to avoid conflicting with the global option 
"qsv_device".

Attached the updated patches.

Thanks.

Subject: [PATCH 1/2] libavcodec/qsvdec: Fix the QSV decoder can't work when
 using system memory

Description: ./ffmpeg -c:v h264_qsv -i in -c:v h264 output.h264 does not
work because the qsv decode will failed.

Root cuase: when using the system rather than the hwaccel,ff_qsv_init_internal_session
does not set the vaDisplay handle for the session. The qsv decode will failed.

Solution: when creating the internal session , call the HwContext API to get session and
release all resource when close the decoder.

That seems to go very much into the wrong direction.

This should probably wait until we have a field for the
AVHWDeviceContext in AVCodecContext, instead of adding absurd hacks
adding slightly differently named option to disambiguate it.
