Play it with your browser and smart-phone!<br>

I've just tested PAL HDV 16:9 and SD-DV 4:3 video clips
rendered with <br>
Cin-GG to AV1 video and Opus audio muxed in a WebM
container.<br>
They playback fine in VLC mediaplayer and not at least in
Firefox and <br>
Google-Chrome browsers on Linux.<br>
<br>
Transferred these WebM clips using Gnome File manager on
Linux to my <br>
smart-phone Google Pixel 7 Pro via USB connection.<br>
Tested these AV1 WebM clips playback worked fine on Pixel
7 with Android <br>
14, possibly using its Tensor hw decoder.<br>

Well, I downloaded mpv for Android, but apparently I have to look
more into it, just to navigate.<br>
While the default Photo app lists the newest (webm) files on top in
the DCIM/Camera.<br>
mpv starts listing at the bottom (2013). I gave up after scrolling
to 2015 :) <br>
Could not see neither opposite listing nor search button.<br>
