fftools/opt_common: check the return value of av_hwdevice_get_type_name before printing it
It may be NULL, as is the case for D3D11VA_VLD.
Running "ffmpeg -h decoder=h264" on a Windows build
Before:
Decoder h264 [H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10]:
Supported hardware devices: dxva2 (null) d3d11va cuda
After:
Decoder h264 [H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10]:
Supported hardware devices: dxva2 d3d11va cuda
