New description:

 ffmpeg -i input.mp4 -c:v libx265 -vtag HEVC -flags:v -global_header -bf 0
 -preset ultrafast -c:a libopus -atag  0x704F -f asf output.asf

 output.asf can be played on Windows Media Player
 But output.asf cannot be played on ffplay

 MFVideoFormat_HEVC 'HEVC'
 See https://docs.microsoft.com/en-us/windows/win32/medfound/video-subtype-
 guids

 WAVE_FORMAT_OPUS (0x704F)
 See https://docs.microsoft.com/en-us/windows/win32/medfound/audio-subtype-
 guids

 Is it posible to modify FFMPEG so as to also accept opening HEVC fourCC
 and 0x704F fourCC for asf?
