Joe have you tried Firefox too? Each time we updated ffmpeg to a new major version we struggled to make Firefox work...

qtwebengine 6.6.3 needs nontrivial changes for deprecation removals. Undoubtedly 6.7.0 also but I am not able to get that to work as I mentioned in another ticket. I have system ffmpeg disabled until this is worked through.

Yes. Firefox builds and runs fine.

Sorry for bothering, but have you tried Youtube? When we updated to ffmpeg 6 there were reports about "it runs fine but cannot play videos."

I had no issues with any of the videos on Youtube.

alsa-plugins-1.2.7.1 also FTBFS with ffmpeg-7.0. Upstream ticket: ​https://github.com/alsa-project/alsa-plugins/issues/57 I configured with --disable-libav to get around it. ffmpeg is listed as optional in the book.

Thanks, I guess the most severe thing will be qtwebengine this time...

I've just cloned current branches of qtwebengine and its chromium stuff. In 118-based chromium it looks as if they took it between 6.0 and 6.1 - the Changelog has items for

Entries are sorted chronologically from oldest to youngest within each release,
releases are sorted from youngest to oldest.

version <next>:
- libaribcaption decoder
- Playdate video decoder and demuxer
- Extend VAAPI support for libva-win32 on Windows
[...]

- Bitstream filter for converting VVC from MP4 to Annex B

version 6.0:
- Radiance HDR image support
- ddagrab (Desktop Duplication) video capture filter
- ffmpeg -shortest_buf_duration option
- ffmpeg now requires threading to be built
[...]

So it seems to be reasonably current. Using the shipped ffmpeg in qtwebengine-6.7 probably won't cause any more vulnerabilities than the backlog of chromium issues still to be backported.

Edit: I thought 6.6 was using 112-based, it is actually 118-based, details amended.

gegl-0.4.48 also FTBFS if ffmpeg-7.0 is installed. Use -Dlibav=disabled when running meson. ffmpeg is listed as optional.

I still can't get QtWebEngine to work despite trying for the last 2 weeks, I've turned off system ffmpeg with an note to whoever updates it next.

[Rahul Chandra]

Thanks for all the info Joe, Ken, and Xi it was really useful
