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 ?

This last one probably not yet in ffmpeg 6.1, I just saw this commit in ffmpeg.git: ====== commit a0821345eb31b727d93c9c3ed7d74d2774c73afa Author: Vignesh Venkatasubramanian via ffmpeg-devel <[email protected]> Date: Wed Oct 4 09:40:15 2023 -0700 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 https://github.com/nokiatech/heif/tree/gh-pages/content/images Also add a couple of fate tests with samples from https://github.com/nokiatech/heif_conformance/tree/master/conformance_files Partially fixes trac ticket #6521. ====== see also bunch of fixes for prores encoders.
