I just haven't noticed any > issues in normal usage yet. Does "normal usage" include WebRTC use? Though even there, you can probably get away with only VP8/VP9 support in most cases. But if you do not have working H.264 encoding and the other end supports only H.264 (e.g., Safari 11 or 12.0, they added VP8 support in 12.1 according to Wikipedia), you are stuck. So it is kinda hard to test it in daily use until problems happen. You can use this page to test: https://mozilla.github.io/webrtc-landing/pc_test_no_h264.html though that might be testing only what the browser CLAIMS to support and not what actually works. That said, dlopening OpenH264 should work in qt6-qtwebengine thanks to these downstream patches: https://src.fedoraproject.org/rpms/qt6-qtwebengine/blob/rawhide/f/qtwebengine-blink-dlopen-h264.patch https://src.fedoraproject.org/rpms/qt6-qtwebengine/blob/rawhide/f/qtwebengine-webrtc-dlopen-h264.patch (We do not have these in qt5-qtwebengine, only in qt6-qtwebengine.)

That includes the DRM blob, and I guess it is one of the locations the QtWebEngine looks for it by default. If you want just Widevine without all of Google Chrome, then it is a game of finding and extracting the blob manually. I do not have Widevine at all, which means things like Netflix are just going to fail with an error message. > If there's a way to get the list or test out the supported codecs, I can > do that and report back. I assume at least H.264 works or Netflix would probably not work, would it? Though have you tried it with the FFmpeg from Fedora or only with the one from RPM Fusion? (In principle, both should support H.264 decoding, the one from Fedora through dlopened OpenH264 with a downstream Fedora patch, the one from RPM Fusion through the built-in decoder in FFmpeg.)

I upgraded here, so maybe I've done this in the past and it's still there.

I have these packages: ``` $ rpm -qa \*264\* x264-libs-0.164-8.20220602gitbaee400f.fc39.x86_64 openh264-2.3.1-2.fc39.x86_64 mozilla-openh264-2.3.1-2.fc39.x86_64 gstreamer1-plugin-openh264-1.22.1-1.fc39.x86_64 ``` Again, not sure if stuff works as it should.
