Samuli Piippo 98eb819c18 qtmultimedia: enable ffmpeg only if its license is accepted

Qt6 OpenEmbedded/Yocto Project layer

This layer depends on:

URI: https://git.openembedded.org/openembedded-core/

and optionally:

URI: https://git.openembedded.org/meta-openembedded/

Yocto version support

The branching of meta-qt6 layer follows Qt branching scheme, that is dev for the development branch, 6.x for minor stabilization branches, 6.x.y for the release branches and lts-6.x.y for commercial LTS releases.

Each Qt release is tagged either as v6.x.y or v6.x.y-lts

Following table shows the Yocto branches which are used to test each Qt version (x) and any additional Yocto releases that are stated in the LAYERSERIES_COMPAT (c).

Commercial Qt

Qt is dual-licensed under commercial and open source licenses. The license can be selected using the QT_EDITION variable. commercial and opensource are valid values. The default value is opensource.

For commercial Qt users, the layer provides additional support with LTS (Long Term Support) releases for selected Qt versions and additional Qt modules licensed as commercial-only.

The LTS releases are available in branches named lts-6.x. The source code for the LTS releases and the commercial Qt modules are only available for commercial Qt license holders. They can only be built and used if you have a commercial Qt license and you have set up SSH access to Qt Gerrit (see links below).

The commercial Qt modules are included in the build if the QT_COMMERCIAL_MODULES variable is set to 1 and you are using a commercial edition of Qt.

QtWebEngine

QtWebEngine needs at least CMake 3.19, which is available starting from Hardknott. For this reason QtWebEngine is not tested on older releases.

QtMultimedia

Qt Multimedia now prefers FFmpeg as the multimedia backend instead of GStreamer. FFmpeg recipe, however, is flagged with LICENSE_FLAGS = "commercial", which means that user must accept the license before FFmpeg can be used in the build. If user accepts the license using LICENSE_FLAGS_ACCEPTED = 'commercial_ffmpeg', the FFmpeg support is enabled in Qt Multimedia. If user doesn't accept the license, Qt Multimedia only uses GStreamer.

Contributing

To contribute to this layer you should submit the patches for review using Qt Gerrit.
