[FFmpeg-user] hdr hevc Invalid NAL unit 0, skipping

[Andy Furniss]

The HDR sample below does play but floods output killing perf.

http://www.demo-uhd3d.com/files/uhd4k/Samsung_SUHD_Picture_Quality%20Demo_Nano_Crystal%20Display_UK-Version.mp4

This is 700meg and won't cut with dd.

The issue still exists with a smaller sample made with

ffmpeg -c copy -t 5
