Convert Flatpak application

bash
ll-pica-flatpak convert org.videolan.VLC --build

TIP

The package name for Flatpak is org.videolan.VLC. It can be found by visiting https://flathub.org/ => clicking on the app => selecting the Install drop-down menu => viewing the package name.

ll-pica-flatpak uses ostree commands to retrieve the application data of org.videolan.VLC, and generates the corresponding linyaps base environment based on the runtime defined in the metadata

The application defaults to generating a uab file. To export a layer file, you need to add the --layer parameter.

bash
ll-pica-flatpak convert org.videolan.VLC --build --layer

To specify the version of the linyaps application to be generated, you need to add the --version parameter.

bash
ll-pica-flatpak convert org.videolan.VLC --version "1.0.0.0" --build --layer

To specify the base environment and version of the linyaps application, you need to add the --base and --base-version parameters.

bash
ll-pica-flatpak convert org.videolan.VLC --base "org.deepin.base.flatpak.kde" --base-version "6.7.0.2" --build --layer

The constructed products are as follows:

bash
├── org.videolan.VLC
│   ├── org.videolan.VLC_1.0.0.0_x86_64_develop.layer
│   ├── org.videolan.VLC_1.0.0.0_x86_64_binary.layer
    or
│   ├── org.videolan.VLC_x86_64_1.0.0.0_main.uab

Layer files are divided into two categories: binary and develop. The binary includes the application's execution environment, while the develop layer, built upon the binary, retains the debugging environment.

The uab file is an offline distribution format used by the linyaps software package, which is not suitable for systems that can normally connect to the linyaps repository. Instead, one should utilize the delta transfer scheme provided by the linyaps software repository to reduce the network transmission size.
