hvc1}}} for the output.

Appreciate your effort to look into the file, adding a tag indeed did the
trick!
So, for the folks, that are looking for a solution, here what I used:
{{{
ffmpeg -vcodec libvpx-vp9 -i input.webm -c:v libx265 -tag:v hvc1
output.mp4
}}}
Please mind that I compiled both `ffmpeg` and `x265` from the upstream.
