AV1 and WebM:
Play it with your browser and smart-phone!

I've just tested PAL HDV 16:9 and SD-DV 4:3 video clips rendered with
Cin-GG to AV1 video and Opus audio muxed in a WebM container.
They playback fine in VLC mediaplayer and not at least in  Firefox and
Google-Chrome browsers on Linux.

Transferred these WebM clips using Gnome File manager on Linux to my
smart-phone Google Pixel 7 Pro via USB connection.
Tested these AV1 WebM clips playback worked fine on Pixel 7 with Android
14, possibly using its Tensor hw decoder.



may be mobile mpv can help to see if hardware decoder was using in this vase ?

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

This last one probably not yet in ffmpeg 6.1, I just saw this commit in ffmpeg.git:

So far, I have just installed several heif plugins (ffmpeg included) from Packman on lp15 (and on tw-sr):

i+ | libheif-aom                         | Plugin AOM encoder and decoder for AVIF                       | package
i+ | libheif-dav1d                       | Plugin dav1d decoder for AVIF                                 | package
i+ | libheif-ffmpeg                      | Plugin FFMPEG decoder (HW acc) for HEIC                       | package
i+ | libheif-HEIF                        | Plugin for HEIF decoder and encoder                           | package
i+ | libheif-jpeg                        | Plugin encoder and decoder for JPEG in HEIF                   | package

    avformat/mov: Add support for demuxing still HEIC images   They are similar to AVIF images (both use the HEIF container). The only additional work needed is to parse the hvcC box and put it in the extradata.

    With this patch applied, ffmpeg (when built with an HEVC decoder)    is able to decode the files in

 Also add a couple of fate tests with samples from

                                                                                                       Partially fixes trac ticket #6521.
