How do you view/check the output from decoding of HEVC stream?

Please note that layout P010 is DIFFERENT than YV12.

mpeg2 and h264 are compressed in 8 bits, hence when decompressed you will get pixel layout known as yv12-planar:
1920x1080 bytes of luma-Y
960x540 bytes of chroma-U
960x540 bytes of chroma-V

h265 is compressed in 10 bits, hence when decompressed you will get pixel layout called P010:
3840x2160 words of luma-Y
3840x1080 words of chroma-interlaced-U+V
(… this chroma-interlaced format is used e.g. by nVidia cards)

So the presentation software needs to handle chroma differently than in case of decoded h264 stream!
