vp9 doesn't work in dash

[kmskrishna]

If you try to use vp9 encoding it works in HLS but not in DASH

Command I used
/usr/bin/ffmpeg -i rtmp://127.0.0.1:1935/video/1080 -c:v libvpx-vp9 -c:a libopus -quality realtime -speed 5 -threads 16 -qmin 4 -qmax 48 -b:v 4000k -f mpegts http://127.0.0.1/publish/1080

I am trying to use RTMP module with this one to use Google's vp9 encoding.

DASH is not supporting vp9 in this module
