openCL cannot be run simultaneously with h264_qsv ?

[laurfb]

Hi.
Trying to run:
ffmpeg -i input.avi -vf unsharph=opencl=1 -f mp4 -c:v h264_qsv output.mp4

ffmpeg hang with error message:
"Display driver stopped responding and has recovered.
Display Driver Intel HD Graphics Driver for Windows 8(R) stopped responding and has recovered"

Seems to run normally with either opencl or qsv alone.

My system: i7-4790K, Intel HD 4600 graphics with latest driver installed.

Bug or am I doing something wrong?
regards,
laur

Does it work with nvidia's opencl, so different devices?
