Summary looping single frame mp4 causes repaint in <img src=mp4>

Single frame MP4 (h264/hevc) in an <img> tag offers a good alternative to jpg because of hardware decode advantage. However, <img src=mp4> assumes muted looping which causes continual repaints of the viewport https://colinbendell.github.io/webperf/img-mp4/index.html https://colinbendell.github.io/webperf/img-mp4/index_hevc.html For situations where there are 1 (perhaps <=2 ?) frames, the <img src=mp4> should not loop.
